Tool Tokens
add_app ~233

Add an app to the account as one of the user's own. Takes an Apptail app_id, an App Store URL, or a name — resolved and imported the way search_apps does. Tracking starts immediately (rankings, reviews, competitors); measured downloads and proceeds still require connecting App Store Connect in the console, which cannot be done from here.

NameTypeReqDescription
appstringyesThe app to claim: an Apptail app_id, a full App Store URL, or the app's name. A URL is the reliable form — a name resolves against the whole store, and two apps can share one.
countrystring–Primary storefront for this app, ISO 3166-1 alpha-2 (e.g. US, DE). Defaults to US. This is the storefront its keywords and rankings are tracked in first; more can be added in the console.
dry_runboolean–Resolve the app and report what would happen without claiming it. Worth doing when the user gave a name rather than a URL, so they can confirm it is the right app before it counts against their plan.
NameTypeReqDescription
appobject|null–The app as it now appears in the account. Null under dry_run only if nothing resolved.
apps_limitintegeryesHow many the plan allows. -1 means unlimited.
apps_usedintegeryesOwn apps in the account after this call.
connectedbooleanyesWhether App Store Connect reports for this app. False for almost every freshly added app — say so, because get_performance will return nothing for it until it is connected in the console.
console_urlstring|null–Where to open this app in the AppTail console.
countrystringyesThe storefront it was added for.
notestring|null–What happens next, when there is something the user should know.
statusstringyes`added` when it is now in the account, `already` when it was there before this call, `would_add` under dry_run.

No examples provided.

add_competitors ~316

Track one or more rival apps against one of YOUR apps. Each competitor can be given as an Apptail app_id, an App Store URL, or just a name — names and URLs are resolved and imported the way search_apps does, so you do NOT need to look up an app_id first. Returns one outcome per item: what was added, what was already tracked, and what a plan limit refused.

NameTypeReqDescription
app_idintegeryesApptail app id for one of YOUR apps — from get_account. The rivals are tracked FOR this app: competitor sets belong to an app, not to the account, so removing one later affects only this app.
competitorsarrayyesThe rivals, up to 20. Each item is an Apptail app_id, a full App Store URL, or an app name in any language. Send all of them in one call — the plan limit is checked per item, so a batch that runs out…
countrystring–Storefront to resolve names in, ISO 3166-1 alpha-2 (e.g. US, DE). Omit and it is guessed from the script the name is written in. Ignored for items given as an app_id.
dry_runboolean–Resolve every item and report what would happen, without tracking anything. Use it when the user named apps ambiguously and you want to confirm you found the right ones before changing their account.
NameTypeReqDescription
added_countintegeryesHow many are now tracked that were not before.
app_idintegeryesThe app these rivals are tracked against.
dry_runbooleanyesTrue when nothing was written. Every outcome then reads `would_add`.
outcomesarrayyesOne row per item, in the order they were sent. Read `status` per row: a batch is rarely all one thing, and reporting it as "done" when two of five were refused is the failure this shape exists to pre…
remaininginteger|null–Competitor slots left for this app on this plan after the call. Null when the plan is unlimited. Zero means the next add will be refused — say so rather than letting the user find out.
requested_countintegeryesHow many items were sent.

No examples provided.

add_keywords ~443

Start tracking search terms for one of your apps, in one storefront. Send terms, or `keyword_ids` for suggestions returned by discover_keywords — a suggestion MUST be added by id, because re-resolving its term can land on a different keyword row. Counts against the plan's per-app keyword limit; `dry_run` reports what would happen without writing anything. Terms already in the corpus come back under `already_tracked` rather than as an error — that is the state the caller asked for.

NameTypeReqDescription
app_idintegeryesApptail app id for one of YOUR apps — get it from get_account. Not the numeric id in an App Store URL (that is apple_app_id). Keywords are tracked per app.
countrystringyesStorefront to track these terms in, ISO 3166-1 alpha-2 (e.g. US, GB, DE). Required and not defaulted: a term tracked in the wrong storefront is a wasted keyword slot. Ranks are per storefront — the s…
dry_runboolean–Report what would be added, and how many slots are left, without tracking anything. Nothing is written and nothing counts against the plan.
keyword_idsarray–Apptail keyword ids to start tracking — the `keyword_id` on a discover_keywords row. Use this rather than the term whenever you have an id: a term is re-resolved and can land on a different keyword r…
keywordsarray–Search terms to start tracking, as a user would type them into the App Store (e.g. ["fitness tracker", "workout app"]). Send the whole batch in one call rather than one term per call. Terms we have n…
NameTypeReqDescription
addedarrayyesTerms now being tracked. Under `dry_run` this is what would be added and nothing was written.
added_countintegeryesSize of `added`.
already_trackedarrayyesThe subset of `skipped` that the app was already tracking. **This is the end state that was asked for, not a fault** — a term already in the corpus needs no retry and no apology. What is in `skipped`…
app_idintegeryesThe app these terms are tracked for.
countrystringyesThe storefront they were tracked in.
dry_runbooleanyesTrue when nothing was written.
limitintegeryesKeywords this plan allows per app. -1 means unlimited.
limit_reachedstring|null–Set when the account's plan limit stopped the run before the whole list was added. A ceiling, not a fault — say what was capped rather than retrying.
remaininginteger|null–Keyword slots left for this app on this plan after the call. Null when the plan is unlimited. Zero means the next add is refused.
skippedarrayyesEverything not added: the union of `already_tracked` and the terms that could not be resolved in that storefront or that ran out of plan room. Do not report this count as a failure without reading `a…
skipped_countintegeryesSize of `skipped`, both reasons together. Subtract `already_tracked` before calling anything a problem.

No examples provided.

discover_keywords ~571

Terms an app could be tracking but is not, merged from every source and each labelled with where it came from: what tracked competitors rank for, what the store's similar apps rank for, what those competitors put in their own titles and subtitles, what the store's own mining surfaced, and — reading the listing cold — what the app's own title, subtitle and description suggest. The last is the only source that works on an app added minutes ago; `listing` is the only one that can surface a phrase nobody has ranked for yet, and it offers a phrase only when two or more rivals publish it and Apple reports somebody searching it. Pass `contains` to also match terms already in AppTail's database. Already-tracked and already-dismissed terms are never returned. This is a list of candidates, not a measure of coverage: for how much of a niche's vocabulary the account is missing, and which holes matter most, call get_landscape and read `term_gap`. Discovery can persist shared suggested keyword records, cache generated suggestions, and queue background popularity collection. It does not add those terms to account tracking.

NameTypeReqDescription
app_idintegeryesApptail app id to suggest for. get_account for the user's own apps. Suggestions are derived from this app's listing, its rivals and its neighbours, so they are only meaningful for the app they were a…
containsstring–Only terms containing this text. With `source: ["corpus"]` this is a search of AppTail's keyword database. Note it searches terms AppTail holds, not the App Store: a phrase nobody has ever tracked re…
countrystring–Storefront to suggest for (e.g. US, DE). Defaults to the app's primary storefront — which is only one of them: an app localized into several languages is searched for in several storefronts, so call…
limitinteger–Max suggestions, most-searched first. Default 60, capped at 200. The answer always says how many there were.
sourcearray–Which sources to read. Omit for all five that need no argument — `competitors`, `similar`, `listing`, `store`, `ai`. `corpus` is a text match against terms AppTail already holds and does nothing with…
NameTypeReqDescription
app_idintegeryesThe app these suggestions are for.
app_namestring|null–Its name.
by_sourceobjectyesHow many suggestions each source produced, keyed by source name; a source with none is absent. **Read this before reporting an empty answer.** Five of the six need something on file — rivals, the sto…
console_urlstring|null–The app's keyword screen in the console, where the same list can be reviewed and added by hand.
countintegeryesSuggestions returned.
countrystringyesThe storefront they apply to.
sourcesarrayyesSources actually read. A source not listed here was not consulted.
suggestionsarrayyesThe terms, most-searched first. Add them with add_keywords using their `keyword_id`, never their text.
totalintegeryesSuggestions found before the cap.
truncatedbooleanyesTrue when `count` is below `total`. Say the list is partial rather than presenting it as everything worth tracking.

No examples provided.

edit_market_corpus ~335

Add terms to one storefront's corpus, or take terms out of it. Add for a term the corpus SHOULD hold and does not — a rival's brand, a phrase Apple has never measured the popularity of, the term a thin storefront is really about; a pinned term is kept through every rebuild and refreshed on the same 72-hour cadence as the rest. Remove for a term that does not belong: ANY term can go, and one the heuristic found is also kept out of future rebuilds rather than returning within 72 hours. This is NOT `save_market`: seeds are what the corpus is expanded FROM and changing one re-runs the whole heuristic over that storefront, where these two writes act on single terms in the result.

NameTypeReqDescription
addarray–Terms to pin, as somebody would type them into the App Store. Send the batch in one call. Terms already in the corpus come back under `already_present` rather than as an error.
countrystringyesWhich storefront's corpus, ISO 3166-1 alpha-2 (e.g. US, DE). Required and not defaulted: a corpus belongs to one storefront, and there is no market-wide term list to add to.
market_idintegeryesApptail market id — from list_markets or save_market.
removearray–Keyword ids to take out of the corpus — the `keyword_id` on ANY get_market corpus row. A term the heuristic found is also recorded as excluded so rebuilds do not re-derive it; `add` on the same term…
NameTypeReqDescription
already_presentarrayyesTerms that were already in this corpus, and where they came from. Not an error — it is the state the caller asked for, and a `competitor` term is NOT re-recorded as `manual`, because the origin says…
capintegeryesThe most terms this storefront may hold, from the account's plan. A market's storefronts each get their own — the cap is per storefront, not shared across the market.
caveatsarrayyesWhat the caller needs to hear before reporting success — that ranks are not in yet, or that the cap cut the list.
console_urlstring|null–This market's corpus in the console.
countrystringyesThe storefront that was edited. A corpus belongs to one storefront and is never shared between them.
excludedarrayyesThe subset of `removed` that will ALSO be kept out of every future rebuild. A term the heuristic found is re-derived from the seeds every 72 hours, so removing it has to be recorded outside the corpu…
market_idintegeryesThe market this corpus belongs to.
not_removedarrayyesIds that were sent to `remove` and are still in the corpus, each with the reason.
pinnedarrayyesTerms added to the corpus by this call, with `origin: "manual"`. A term Apptail has never seen is created and queued for crawling, so its ranks appear within minutes rather than immediately.
refusedarrayyesTerms not added because the storefront is at `cap`. Unpin something or drop a storefront; the account's plan sets the number.
removedarrayyesKeyword ids taken out of the corpus by this call.
termsintegeryesHow many terms this storefront's corpus holds now.

No examples provided.

explain_period ~394

Return an account or owned-app summary for a requested period: available measured App Store Connect performance, storefront changes, tracked keyword movements, recorded signals, review volume and the last sent digest. Returns comparison data, coverage and caveats identifying unavailable sections. Reads account data without changing tracking or publishing content.

NameTypeReqDescription
app_idinteger–Narrow to one of the account's own apps — get_account lists them. Omit for the whole portfolio, which excludes apps the owner has hidden.
comparestring–What to read the period against. `previous` (the default) is the period immediately before — for a calendar month, the calendar month before. `year_ago` is the same dates a year earlier, for comparis…
countrystring–Storefront for the keyword half only; the money is reported across all of them with a per-storefront split. Defaults to the app's primary storefront. Ranks only exist per storefront.
fromstring–Start date, `YYYY-MM-DD`, inclusive. Overrides `period` when both are sent. Send it alone and the window runs to today.
periodstring–The window to report on. A calendar month as `2026-07`, a calendar year as `2026`, `last_month`, `this_month`, `last_year`, or a trailing window: `today`, `7d`, `14d`, `30d`, `90d`, `180d`, `365d`, `…
tostring–End date, `YYYY-MM-DD`, inclusive. Send it alone and the window is the three years before it.
NameTypeReqDescription
app_idsarrayyesThe apps this covers.
caveatsarrayyesEverything the reader has to hear before this reads as a complete picture: apps with no connection, a window shortened to the last day Apple reported, a corpus larger than the movers shown. **Pass th…
comparison_windowobject|null–What everything here is read against. Null when `compare` was `none`.
digestobject|null–**What the customer was last mailed** — the weekly digest, sent Wednesdays, that leads with the measured week and at most three moves. Null when none has gone out yet. Anything here is breakfast read…
headlinearrayyesThe two or three sentences a person would open with, each carrying its own figures. Lead with these; everything below is the evidence for them.
keywordsobject|null–The keyword half. Null when the account tracks no apps.
performanceobject|null–The measured half. **Null when the account has no apps at all**, and present with null figures when it has apps but no App Store Connect connection — those are different answers, and the caveats say…
reviewsobjectyesReview arrivals — a flow, counted over the period. Not the backlog of unanswered reviews, which has no window and is on the console's reviews screen.
signalsobjectyesWhat the product itself detected. A stored record, not a reconstruction — quote these sentences rather than re-deriving them from the numbers.
windowobjectyesThe window actually read, which is not always the one asked for: an inverted range is swapped, a range past three years is shortened, and first-party figures are pulled back to the last day App Store…

No examples provided.

get_account ~212

The account: its apps with Apptail ids, its plan and the limits that can refuse a write, App Store Connect health per app, how fresh the first-party data is, and the storefronts it focuses on. Call this first whenever the request is about "my app" or "my keywords" — every other tool needs an app_id, and the focus countries and hidden apps here are what keep your answer agreeing with what the customer sees in the console.

NameTypeReqDescription
include_competitorsboolean–Also return the rival apps tracked under this account's apps, each marked `is_competitor`. Default false: including them makes any portfolio total wrong, and get_competitors is the tool that answers…
include_hiddenboolean–Also return apps the owner has set aside. Default true, because they are still tracked and still answerable — each one is marked `hidden: true`, and they must be left out of portfolio totals. Set fal…
NameTypeReqDescription
appsarrayyesThe account's apps. `app_id` here is what every other tool takes; the numeric id in an App Store URL is `apple_app_id` and will not work.
connectionobjectyesApp Store Connect health for the account. A `failed` or `stale` connection looks exactly like a quiet fortnight in the numbers, which is why it is stated separately rather than left to be inferred. `…
countintegeryesNumber of apps returned.
data_throughstring|null–Most recent day App Store Connect reported anywhere in the account. Per-app dates are on each app, and they differ — one healthy app keeps this recent while another has been silent for weeks.
focus_countriesarrayyesThe storefronts this account actually watches, in its own order. Every console screen narrows to these. Narrow your answers to them too unless the user asks otherwise — an answer across all 122 store…
planobjectyesThe plan and its ceilings, read from the services that enforce them — so a refusal cannot disagree with this. Tell the user what was capped rather than working around a limit.

No examples provided.

get_app ~570

Everything AppTail holds about one app, at the depth you ask for. The base answer is the store listing **in one storefront** — the localised title and subtitle a shopper in `country` actually reads, the price and its currency, version, category, release dates, the publisher's ids. `include` adds sections: `prices` (what it costs in every storefront), `ratings` (every storefront's rating and vote count, pooled honestly, plus a daily series and per-storefront movement with `history_days`), `charts` (the charts it currently ranks in), `popularity` (organic reach), `developer` (the publisher and its portfolio), `versions` (release cadence) and `screenshots`. Works for ANY app in the store, not only the user's own. It does NOT return impressions, downloads or revenue — get_performance does, and only for the user's own connected apps.

NameTypeReqDescription
app_idintegeryesApptail app id. get_account for the user's own apps, search_apps for any other app in the store. Not the numeric id in an App Store URL (that is apple_app_id).
countrystring–Storefront to read the listing in (e.g. US, GB, DE). Defaults to the app's primary storefront. Title, subtitle, price, rating and screenshots all differ per storefront, so this changes the answer rat…
history_daysinteger–With `include: ["ratings"]`, also return the rating and the vote count day by day, this many days back from today, **and how each storefront moved over that window** — `ratings_gained` and `rating_ch…
includearray–Extra sections to read. Omit for the listing alone, which is the cheap answer. `ratings`, `charts` and `popularity` need a Starter or Pro plan and are refused by name without one — the rest are free.…
NameTypeReqDescription
app_idintegeryesApptail app ID. This is the `app_id` every other tool expects.
apple_app_idinteger|null–Apple's own numeric app ID, as it appears in App Store URLs. Not interchangeable with `app_id`.
bundle_idstring|null–Store bundle identifier, e.g. "com.burbn.instagram".
chartsarray–Charts the app currently ranks in, across all countries and categories. Present only with `include: ["charts"]`; empty means it charts nowhere.
console_urlstring|null–Where to open this app in the AppTail console — the owner's own dashboard when `is_mine`, the research view otherwise. Null where this environment serves no console. End an answer about an app with i…
countrystring|null–Storefront the metrics below were read from. Defaults to `primary_country`.
currencystring|null–ISO code of the currency `price` is in, derived from `country`. A price without it is a number, not an amount — several storefronts print a "$" and mean different money.
current_version_release_datestring|null–Date the current version shipped (YYYY-MM-DD). Useful as an update-cadence signal.
developerobject|null–The publisher and its portfolio — with the cap on `top_apps` declared. Present only with `include: ["developer"]`; null there when AppTail holds no profile for the publisher.
developer_idinteger|null–Apptail developer ID. Pass this as `developer_id` to get_developer_info. Null if we hold no profile for the publisher.
has_inappsboolean|null–Whether the app offers in-app purchases.
iconstring|null–Absolute URL of the app icon.
includesarrayyesThe sections actually read. A section absent from this list is absent from the answer because nobody asked for it — which is not the same as it being empty.
is_mineboolean|null–True when this is one of the asking account's own apps. Null when the call carried no account — get_top_charts answers without a token — which is "not known here", not "no".
is_tracked_competitorboolean|null–True when the account already tracks this app as a competitor of one of theirs. False on a high-ranking rival is a suggestion worth making: add_competitors starts watching it. Null when the call carr…
listing_storefrontsarray–One storefront per language the listing is localized in, `primary_country` first, e.g. ["ru", "us"]. An app published in two languages is searched for in two storefronts; keyword discovery and tracki…
namestring|null–The app's title **as published in `country`** — the string a shopper in that storefront reads, which is also the string Apple indexes. It is not a translation of one canonical name: an app localised…
popularityobject|null–Organic reach in `country`. Present only with `include: ["popularity"]`, and **null there when no storefront could be resolved** — a key that is present and null means "asked for, nothing to read", w…
pricenumber|null–Download price in `country`, in that storefront's own currency and in major units — 9.99, never 999. 0 means free, which is what most apps are; `currency` names the money. Null when this storefront h…
pricesobject|null–What the app costs to download, per storefront. Present only with `include: ["prices"]`. This is the download price alone: `has_inapps` says whether there is more to pay after that, and get_app does…
primary_categoryinteger|null–Store category ID. Pass this as `category` to get_top_charts.
primary_category_namestring|null–Human-readable name of `primary_category`, e.g. "Health Fitness".
primary_countrystring|null–Lowercase ISO country code of the app's main storefront, e.g. "us".
privacy_policy_urlstring|null–Privacy policy URL.
rating_averagenumber|null–Mean star rating (1-5) in `country`. Null if the app has no ratings there yet.
rating_countinteger|null–Number of ratings in `country`.
ratingsobject|null–Present only when `ratings` is in `include` — a section you did not ask for is absent from the answer entirely, which is not the same as it being empty.
release_datestring|null–Date the app first appeared in the store (YYYY-MM-DD).
screenshotsobject|null–Present only with `include: ["screenshots"]`, and null there when no storefront could be resolved.
seller_urlstring|null–Publisher's marketing website.
storestring|null–Which store the app belongs to.
store_developer_idinteger|null–The store's own publisher ID, as it appears in store URLs. Not interchangeable with `developer_id`.
subtitlestring|null–The subtitle under the title in `country` — thirty characters Apple indexes as heavily as the title, and the field most competitors leave generic. Null when the storefront listing has none, which is…
support_urlstring|null–Support page URL.
tierinteger|null–Apptail activity tier for `country`: 1 = currently charting, 2 = shipped more than two updates in the last 180 days.
versionstring|null–Latest published version string.
versionsobject|null–Release history. Present only with `include: ["versions"]`. Cadence is the one competitor signal readable straight off the store: four releases in six weeks then eight months of nothing is a team tha…

List tracked competitor apps for one of your apps, with how many more the plan allows — and `suggested`: up to ten rivals the account does not track yet, ranked by how many of the app's own search terms they sit in the top ten for. Works on an app with no keywords: its listing is read for terms and the store is crawled for them. Read `suggested_basis.terms_pending` before calling a short list complete. Suggestions can persist shared keyword records and queue background crawls. Suggested apps are not added to your competitor watchlist.

NameTypeReqDescription
app_idintegeryesApptail app id for one of YOUR apps — get it from get_account. Not the numeric id in an App Store URL (that is apple_app_id).

suggested_basisobject|null–What the suggestions were derived from. Null when the app is not one of the account's own — a suggestion needs your terms to read.

get_keyword_serp ~518

The App Store search results for one term in one storefront, on one day: who ranked, in what order, with their names, subtitles and ratings. This is how you find out WHO took the places an app lost — a rank that fell is a fact, and the results page on the day it fell is the reason. Works for ANY term in the store, tracked or not, known to us or not: pass `keyword_id` for a term you already have an id for, or `keyword` + `country` for words a user typed, which resolves the term and crawls the storefront live when what we hold is over a day old. Omit the date for the most recent crawl. A lookup can persist a new shared keyword record and queue a background crawl that updates stored search observations. It does not track the keyword for your account.

NameTypeReqDescription
countrystring–Storefront for `keyword`, e.g. "us", "jp". Required with `keyword` and ignored with `keyword_id`, because a keyword already names its storefront. There is no worldwide search results page — every App…
datestring–The day to read, `YYYY-MM-DD`. Omit for the most recent crawl, which is the only mode that ever crawls live — naming a day is a question about the past and is answered from what was recorded. A day n…
keywordstring–The search term itself, for words a user typed rather than an id — "sleep tracker", "заметки". Needs `country`. A term nobody has ever looked up is created and the storefront is read live, so this an…

limitinteger–How deep to read. Default 25, capped at 50. Below about 25 nobody is competing with you for the term.
NameTypeReqDescription
appsarrayyesThe results in rank order, best first. `is_mine` marks the account's own apps and `is_tracked_competitor` marks rivals it already watches — a high-ranking app that is neither is worth suggesting they…

countintegeryesApps returned.

crawledbooleanyesWhether that day had a crawl at all. False with an empty list means nobody measured, **not** that nobody ranked.
crawled_daysarrayyesDays in the last 30 that were crawled, newest first. Name one in `date` to see how the results looked then — comparing two days is what shows who took a place.

results_countinteger|null–How many apps the store returns for this term in total. The results below are the top of that.

No examples provided.

get_keywords ~1,078

The account's tracked keywords for an app — or across the whole portfolio — over any window: where each term ranked at the start and end, how far it moved, how many days it held and how many days it was measured, and optionally its day-by-day history, the same terms measured for named competitors, Search Visibility (a 0–100 score per storefront with the terms that moved it), and the terms two of your own apps are both on. Sorted worst movement first by default, so "what dropped" is at the top of a 300-term corpus — which also makes the returned rows a selection rather than a sample: `movers` and `coverage` are counted over the whole corpus and are what a summary comes from. Filter by `contains` to ask about one term by name. This is the tool for every question about tracked terms; it replaces get_tracked_keywords, get_keyword_positions and compare_keyword_positions.

NameTypeReqDescription
app_idinteger–Apptail app id for one of YOUR apps — get_account lists them. Required for `scope: "app"`. Not the numeric id in an App Store URL (that is apple_app_id).

get_landscape ~412

Who the App Store shows beside one of your apps for the terms it competes on, in one storefront: every app in the niche with how many of your terms it ranks for and owns the top 10 for, its ratings, its review flow and its size, plus which apps arrived or fell out this window — and `term_gap`, how much of the niche's own vocabulary you do not track yet, with the biggest holes ready for add_keywords. This is the niche, not your watchlist: most rows are apps nobody added, and get_competitors answers the other question.

get_market ~871

Read iOS App Store niche data by saved market_id or by query and countries. Returns storefront competition, search visibility, app membership and optional corpus or movement data. Phrase research can create shared keyword records and persist crawled search observations; it does not save an account market. Downloads and revenue are labelled third-party rolling 30-day estimates. Reports per-storefront values, coverage and caveats.

get_performance ~598

Read measured App Store Connect impressions, store views, downloads, sales and proceeds for apps connected to the authenticated account. Supports an owned app or portfolio, documented time windows, period comparisons and breakdowns by storefront or traffic source. Returns the actual reporting window, connection coverage and caveats. Does not provide private analytics for apps outside the account.

get_reviews ~792

Reviews for any app over a window, filtered by storefront, star rating, text, or whether the developer has replied — plus the shape of the period: how many arrived per bucket, what they averaged, and where the app's pooled store rating stood while they did. Reviews exist for every app whether or not App Store Connect is connected, because they are read from the public store. This is the tool for "what are people complaining about": filter it and read the reviews yourself rather than asking for a summary. Every review says whether it can be answered (`can_reply`) and where an existing reply stands (`reply_state`); `reply_to_reviews` is what answers them.

get_signals ~601

What actually happened, from the record the product keeps: rank moves on tracked terms, chart entries, review spikes, competitor releases and price changes, plus — for the user's own apps only — week-over-week traffic and conversion shifts, download collapses, new reviews and rating moves. Each carries the two numbers behind it and the sentence that states the finding. This is a stored table read, not a reconstruction, so it is both cheaper and more reliable than diffing rank histories yourself. Covers the user's own apps and the competitors tracked under them; a rival's finding never `asks_action`.

by_typeobjectyesHow many of each kind the window holds — the shape of the period, counted over everything rather than over the capped list. A key is absent when there were none.
countintegeryesFindings returned.
digestobject|null–What the product has already told this person, when `include_sent` was set. Null otherwise, which means "not asked" rather than "never mailed".
signalsarrayyesThe findings, newest first. Each carries the sentence that states it and the two numbers behind it. Empty is a real answer: it means nothing crossed a detector's threshold, which is the only way a th…
totalintegeryesFindings the window holds in total. Larger than `count` when the list was capped.
truncatedbooleanyesTrue when `count` is below `total`. Say the list is partial rather than presenting it as everything that happened.
windowobjectyesThe window actually read, which is not always the one asked for: an inverted range is swapped, a range past three years is shortened, and first-party figures are pulled back to the last day App Store…

get_top_charts ~262

Get top app charts (free, paid, or grossing) for a store, country, and category.

NameTypeReqDescription
categorystring–Apple category id as a number, e.g. 6014 Games, 6015 Finance, 6017 Education, 6023 Food & Drink, 6013 Health & Fitness, 6012 Lifestyle. Omit for the overall chart across all categories. An id we do n…
chart_typestring–Which chart. Default free. Use grossing for revenue questions — top free ranks by downloads and says nothing about money. An unrecognised value falls back to free and the reply says which chart it re…
countrystring–Storefront to read the chart for (e.g. US, GB, JP). Defaults to US. An unrecognised code falls back to US rather than failing — the reply echoes the storefront actually used, so check it.
limitinteger–How deep to read the chart. Default 25, capped at 100.
storestring–Only the App Store is covered. Google Play is in the data model but nothing is crawled for it, so omit this.
NameTypeReqDescription
appsarrayyesChart entries, rank 1 first. Empty when no chart data exists for this country/category combination.
chart_typestringyesWhich chart was read.
countintegeryesNumber of entries returned.
countrystringyesStorefront the chart was read from.

No examples provided.

list_markets ~247

List markets saved by the authenticated account, including market ids, storefronts, competition ranges, app counts and observed changes for the requested period. Reads saved account configuration and market observations without creating, updating or deleting markets. Returned ids can be used with get_market.

NameTypeReqDescription
fromstring–Start date, `YYYY-MM-DD`, inclusive. Overrides `period` when both are sent. Send it alone and the window runs to today.
periodstring–The window to report on. A calendar month as `2026-07`, a calendar year as `2026`, `last_month`, `this_month`, `last_year`, or a trailing window: `today`, `7d`, `14d`, `30d`, `90d`, `180d`, `365d`, `…
tostring–End date, `YYYY-MM-DD`, inclusive. Send it alone and the window is the three years before it.
NameTypeReqDescription
countintegeryesMarkets this account keeps.
limitintegeryesHow many its plan allows. Equal to `count` means the next save is refused; say so before the user tries.
marketsarrayyesOne entry per market, newest first. Pass a `market_id` to get_market with include: ["members"] for the leaderboard behind any of them.
windowobjectyesThe window every change figure below is measured over.

No examples provided.

remove_competitors ~179

Remove one or more competitor tracking relationships for an app owned by the authenticated account. Accepts AppTail app ids, App Store URLs or names. Name and URL resolution can query the public App Store and import shared app records. Removes the selected pairing only; public apps and pairings for other apps remain. Requires write authorisation and returns one outcome per item.

NameTypeReqDescription
app_idintegeryesApptail app id for one of YOUR apps — from get_account. Only this app's competitor set is touched.
competitorsarrayyesThe rivals to stop tracking, up to 20. Each item is an Apptail app_id (as returned by get_competitors), a store URL, or a name. Ids are the reliable form here — a name is resolved against the whole s…
NameTypeReqDescription
app_idintegeryesThe app these rivals were tracked against.
outcomesarrayyesOne row per item. `not_tracked` means it was not a competitor of this app to begin with — the end state is what was asked for, but do not report it as a removal.
remainingintegeryesHow many competitors this app still tracks.
removed_countintegeryesHow many pairings were actually removed.
requested_countintegeryesHow many items were sent.

No examples provided.

remove_keywords ~151

Remove tracked keywords from an app. Frees the slots against the plan limit; position history is kept, so re-adding a term later does not start from nothing.

NameTypeReqDescription
app_idintegeryesApptail app id for one of YOUR apps — get it from get_account. Not the numeric id in an App Store URL (that is apple_app_id).
keyword_idsarrayyesApptail keyword ids to stop tracking, as returned by get_keywords. Ids, not terms — two apps can track the same word and only these rows are removed. Frees the slots against your plan limit. Position…
NameTypeReqDescription
app_idintegeryesThe app these terms were tracked for.
remainingintegeryesHow many keywords this app still tracks, across every storefront.
removed_countintegeryesHow many keywords were actually untracked. Lower than `requested_count` when some IDs were not tracked for this app.
requested_countintegeryesHow many keyword IDs were passed in.

No examples provided.

remove_market ~153

Delete a saved market, or just one of its storefronts. Pass `store` to drop a single storefront and leave the rest of the market with its corpora and its build clocks untouched; omit it to delete the whole market. Deleting frees a slot on the account's plan. The terms themselves are not deleted — they are shared with any other market or tracked app using them.

NameTypeReqDescription
market_idintegeryesApptail market id — from list_markets.
storestring–Drop only this storefront, ISO 3166-1 alpha-2. Omit to delete the whole market. Dropping the last storefront deletes the market too, because a market asked nowhere is not a market.
NameTypeReqDescription
deletedbooleanyesTrue when the whole market is gone. False when only a storefront was dropped and the market remains.
market_idintegeryes–
markets_remainingintegeryesMarkets left on the account after this call.
namestringyes–
remaining_storefrontsarrayyesWhat the market is still asked in.
removed_storefrontsarrayyesWhat this call removed.

No examples provided.

reply_to_reviews ~205

Create, update or remove public App Store review responses for apps owned by the authenticated account, using its connected App Store Connect API key. Requires write authorisation and eligible review ids. Submitted text is sent verbatim under the developer's name. Obtain approval for the exact text or requested removal before submitting. dry_run validates without publication. Accepts up to ten items and returns per-item outcomes; pending means Apple has accepted a response but has not published it.

NameTypeReqDescription
dry_runboolean–Check every item and report what would happen, without publishing anything. **Worth using by default here** — it confirms the reviews resolve, the account's key reaches their apps and the text fits,…
repliesarrayyesThe replies, up to 10 per call. Send them in one call rather than one at a time: each is answered separately, so a batch where one app is not covered still posts the rest and says which it did not.
NameTypeReqDescription
dry_runbooleanyesTrue when nothing was sent to Apple. Every outcome is then what *would* have happened.
failed_countintegeryesHow many did not do what was asked. Never report a batch as done while this is above zero — say which ones and why.
max_itemsintegeryesThe per-call cap. A request above it is refused as a whole rather than silently trimmed.
outcomesarrayyesOne row per item, in the order they were sent. Read `status` per row, then `state` on the ones that posted.
posted_countintegeryesHow many replies Apple took. Read each one's `state` before calling any of them published.
removed_countintegeryesHow many replies were taken down.
requested_countintegeryesHow many items were sent.

No examples provided.

save_market ~342

Create or update a saved market in the authenticated account from a query, countries and optional per-storefront seed terms. An existing name updates that market, adding storefronts or replacing seed configuration and rebuilding requested storefronts. Persists account configuration and queues background corpus collection using public App Store data. Requires write authorisation. Returns market_id, build status, affected storefronts and caveats; collection may still be pending.

NameTypeReqDescription
countriesarrayyesStorefronts to ask it in, ISO 3166-1 alpha-2 (e.g. ["US","DE"]). Each keeps its own corpus; nothing is blended across them.
namestring–What to call it. Defaults to `query`. Passing the name of a market this account already has ADDS the new storefronts to it rather than creating a second one.
querystringyesThe phrase to build the market from, e.g. "AI calorie tracking". Used as the seed in every storefront unless `seeds` overrides it.
seedsobject–Per-storefront seed terms, keyed by country code: {"de": ["kalorienzähler"]}. OPTIONAL, and optional per storefront. A storefront you leave out is not seeded from `query`: its terms are read off the…
NameTypeReqDescription
added_storefrontsarrayyesThe ones this call added or rebuilt.
caveatsarrayyesWhat the caller needs to hear — that the build is not finished, or that a storefront was seeded from an English phrase.
console_urlstring|null–The market in the console.
createdbooleanyesTrue for a new market, false when storefronts were added to one that already existed.
market_idintegeryesPass it to get_market to read the market once it has built.
namestringyes–
slugstringyesIts address in the console.
statusstringyes`building` immediately after a save. A market is building while ANY storefront is; each one lands separately. A build that dies leaves the storefront `failed` (or `ready` with `failed_at` set when a…
storefrontsarrayyesEvery storefront this market is now asked in, including ones it already had.

No examples provided.

search_apps ~300

Search for iOS apps by name, bundle ID, or App Store URL. Supports all languages including Cyrillic, Chinese, etc. If the app is not in our database, it will be fetched from the App Store, persisted as a shared public app record, and queued for enrichment. This does not add the app to your account or competitor watchlist. Auto-detects the likely App Store region from the query language (e.g. Cyrillic → Russia, Chinese → China). To add what you find, add_competitors and add_app take the same name or URL directly — you do not have to look up an app_id first.

NameTypeReqDescription
countrystring–Storefront to search (e.g. "us", "ru"). Omit and it is guessed from the script the query is written in — Cyrillic implies ru, and so on. Pass it explicitly when the user names a market, because the g…
limitinteger–Max results. Default 10, capped at 25.
querystringyesApp name in any language, a bundle id (com.example.app), or a full App Store URL. Searches Apptail first and falls back to the App Store, importing anything it finds — so this returns a usable app_id…
NameTypeReqDescription
appsarrayyesMatching apps, best match first. Empty when nothing was found.
countintegeryesNumber of apps returned.
countrystring|null–Storefront that was searched. Null when answered from the local database, which is not country-specific.
hintstring|null–Present when nothing was found: suggests how to retry.
notestring|null–Present when the results need a caveat, e.g. data still being fetched in the background.
sourcestringyesWhere the results came from. "app_store" means they were just imported and are still being enriched.

No examples provided.

tag_keywords ~479

Put tracked keywords under a tag, in bulk — or clear their tag — and/or say whether they are brand terms for Search Visibility. The tag is named, not looked up: a name that does not exist yet is created. A keyword carries at most one tag, so assigning replaces whatever it had. `brand` is separate from tags: `own` (your app's name) and `competitor` (a rival's name) leave the terms out of the visibility score, `none` counts them whatever detection says, `auto` hands them back to detection. Send `brand` without `tag` to change only that — the tags stay as they are. This is the tool for organising a large corpus after reading it with get_keywords, which is drudgery in the console and one call here.

NameTypeReqDescription
app_idintegeryesApptail app id for one of YOUR apps — from get_account. Tags belong to an app.
brandstring–Whether these terms are somebody's name, for Search Visibility (get_keywords `include: ["visibility"]`). `own` = your app's name, `competitor` = a rival's: both are listed and left out of the score,…
colorstring–Hex colour for a tag being created, e.g. "#2563eb". Ignored when the tag already exists. Omit and one is picked from the palette that the app is not already using.
keyword_idsarrayyesApptail keyword ids to tag, as returned by get_keywords. Ids, not terms. Up to 500 in one call. A keyword the app does not track is reported back rather than silently ignored.
tagstring–The tag name to put them under. Created if it does not exist. Omit — or send null — to clear the tag off these keywords instead.
NameTypeReqDescription
actionstringyes`assigned` when a tag was set, `cleared` when the tag was taken off, `untouched` when only `brand` was sent and the tags were left as they were.
app_idintegeryesThe app whose corpus was changed.
brandstring|null–The brand decision applied (`own`, `competitor`, `none`, `auto`), or null when none was sent. Search Visibility recomputes on the next get_keywords read.
brand_changed_countintegeryesHow many keywords took the brand decision. 0 when `brand` was not sent.
changed_countintegeryesHow many keywords had their tag changed. 0 on a brand-only call.
requested_countintegeryesHow many keyword ids were sent.
tagobject|null–The tag the keywords now carry. Null when the action was `cleared`.
tag_createdbooleanyesTrue when this call created the tag rather than reusing one. Worth mentioning: a typo makes a second tag rather than an error.
tagsarrayyesEvery tag this app now has, so a follow-up call does not have to guess at names.
unknown_idsarrayyesIds this app does not track, so nothing was changed for them. Empty on a clean run. Never present these as tagged.
