RedditAPIs

Returns the remaining credit balance and usage totals of the account behind this API key. Free: not metered, and costs no credit. A 402 from a metered call means the balance is exhausted; that response carries a top-up URL.

Returns the payment history of the account behind this API key: each top-up's amount, the credits it added, its status and when it happened, newest first. Free: not metered, and costs no credit.

Search the Reddit ads library: promoted posts advertisers run on Reddit, with advertiser, title, landing page, call to action, media, every subreddit each ad appeared in, first and last seen dates and sightings. Reddit's own house ads are excluded. Newest first; page with cursor. Billed at the read rate, the same as a post search.

Bulk-fetches posts by their t3_ fullnames in ONE call (up to 100), in place of a request per post. Takes a comma-separated list of fullnames from a search or listing. Returns posts with title, author, score, comment count, and permalink, the same post shape as the listing endpoints. The result is not necessarily one-to-one with the request, and `meta` reports which: `listing_status` is `complete` only when every fullname came back, `truncated` is a boolean, and `missing_fullnames` names exactly which ids did not come back. Example: fullnames='t3_abc123,t3_def456'.

Posts a comment on a Reddit post as the connected account. A public action on Reddit under the customer's name, marked as a write so a client can ask before it runs. The text is posted as Reddit markdown. Billed at the write rate. With no connected session it answers 400 asking for cookies.

Stores the customer's own Reddit session once, so the comment, submit, vote and DM tools in this server act as that account without cookies in later calls. The session is kept server-side, encrypted (AES-256-GCM, key held only by the API), against this API key's account, after a check with Reddit: a logged-out session is refused with SESSION_LOGGED_OUT. Takes Reddit's session and loid cookies (from the REST login endpoint or the customer's own browser), plus the CSRF cookie for voting and messaging. Connecting again replaces the stored session. Free.

Comment search that returns the ACTUAL comments whose body matches the keyword, sorted by score (highest first), with body, score, author, a comment-deep permalink, and the parent post. It fetches each matching post's comment tree and filters the comment bodies, so the results are first-hand opinions and answers rather than parent posts. Premium call (it fans out into several reads): `limit` sets how many parent POSTS to expand, 1-25 (default 5), not how many comments come back. The response's `after` cursor expands the NEXT batch of parent posts. `max_comments` optionally caps how many comments come back (the top-scored are kept). Matching is on the visible comment text at word boundaries (link URLs are ignored), so every result mentions the query where a reader can see it. Best-effort: a deleted or deeply-nested comment may be missed (meta.truncated flags when a tree was too deep). Each parent post is its own comment-tree read and one can fail while the others succeed: meta.partial is true with meta.trees_failed and meta.trees_fetched when that happened, so the result covers fewer parent posts than it scanned; the call fails only when every tree failed and at least one was refused upstream. group_by='author' switches to a research mode that returns WHO is talking about the query (distinct people ranked by matching-comment count) in place of a flat comment list, capped by max_authors. Example: q='best mechanical keyboard' sort='relevance' t='year'.

Deletes the stored Reddit session for this account. After this, the write tools answer with a request for cookies until a session is connected again. Idempotent: `deleted` is false when nothing was stored. Free.

Sends a private Reddit chat message as the connected account. A direct message to a real person under the customer's name, marked as a write so a client can ask before it runs. Messaging needs the CSRF cookie in the stored session. Billed at the DM rate.

Returns the provenance of the rows this server has already fetched in this session: per completed call, the tool that made it, the endpoint it reached, the timestamp the response arrived, how many seconds old that copy now is, the upstream request id and the response size. Provenance is recorded per call, so every row in one response shares it. The redditapis.com read path holds no response cache for customer reads, so each call is served live at the moment it runs and the age reported here is the age of this session's copy of the rows rather than the age of a stored row; `response_cache` says so in the result. The ledger holds the 20 most recent completed calls, lives in memory, starts empty, is scoped to this server and carries no other caller's calls. How long each category of data is kept is published at https://www.redditapis.com/privacy-and-data-handling.

Returns the status of a feedback report this account sent earlier, by its server id: status new, triaged, shipped or declined, the team's response text if any, and updated_at, which moves only when the team acts on it. Free per call. 404 if the id is not on this account.

Lists the feedback reports this account has sent, newest first, with each one's current status. The server id is returned only once, when a report is sent, so this listing is how a report whose id was not kept is found again; it also shows whether a report landed and whether the team has acted on it. Optional filters by status or type; paging uses the cursor from a previous response. Free per call, not metered. Returns {feedback: [...], count, limit, next_cursor}; pages continue while next_cursor is non-null, and an account that has filed nothing gets an empty list and a 200, not an error. It lists SENT reports on the server, which differ from the unsent local drafts on this machine.

Reports a product problem or gap in redditapis.com to its team, through a local draft queue. action "draft" (the default) writes a report to a queue on this machine and sends nothing; it makes no network call. action "list" returns the pending drafts with their ids. action "send" posts the named draft ids to POST /feedback (free, not metered) and returns a server id per report. action "discard" drops the named drafts. The queue holds at most 10 drafts; a draft past that is refused. A draft takes `type`, a one-line `title` (at most 120 characters), `details` (at most 8000 characters) and optional `area` and `evidence`; evidence keys left out (tool, endpoint, HTTP status, request id) are filled from the last failing call in this session, and the MCP version and client name are attached to every report.

Reads the caller's own Reddit home feed, the front page their subscriptions produce. The other read tools are served from a shared pool of accounts and so cannot return a personal feed; this one sends the caller's session. Requires the caller's Reddit session cookies (session and loid) from POST /api/reddit/login on the REST API, which is not an MCP tool. Without them it returns 400, because Reddit's logged-out front page is a different feed belonging to nobody rather than a thinner version of the caller's. Same post shape and `after` cursor as the subreddit listing. Example: sort='best' limit=25.

Creates a Reddit monitor: watches one or more subreddits, or ALL of Reddit, for new posts (or comments, via `kind`) matching a filter, and delivers every match to the account's registered webhooks. With `subreddit` absent and `q` set, it is a sitewide keyword monitor covering every subreddit at once (posts only). By default matches go to EVERY active webhook on the account; `webhook_ids` routes this monitor's matches to specific webhooks. Every redditapis.com account holds a free entitlement of ONE all-of-Reddit post watch at a 60s cadence (up to 10,000 deliveries a day), so that monitor needs no subscription. Naming a `subreddit`, matching comments, a faster cadence and any additional watch require a paid plan. Needs at least one free monitor slot (the `slots` object in the monitor list). Forward-looking only, from the moment of creation or from `baseline_item_id` if given; posts that already existed are not backfilled. Returns the created monitor (with its `id`) on success, or `subscription_required` (402) if the account holds no recognised entitlement at all, `subreddit_scope_requires_paid_plan` (402) if a free account named a `subreddit`, `monitor_slots_exhausted` (402) if the plan's slot limit is reached, `sitewide_slots_exhausted` (402) if the plan's separate sitewide cap is reached, `distinct_subreddit_limit_reached` (402) if the account already watches as many DIFFERENT subreddits as the plan covers (the limit counts distinct subreddits across all the account's monitors, not monitors, and the same subreddit in two monitors counts once; `slots.distinct_subreddits_total` in the monitor list), `sitewide_comment_monitoring_not_available` (501) if a sitewide monitor asks for comments, `subreddit_reserved` (400) if `subreddit` names 'all', `subreddit_not_found` (400) if a named subreddit does not exist, or `webhook_not_found` (400) if a `webhook_ids` entry is not on this account.

Delivery history: the actual Reddit posts a monitor's webhook has received (or attempted), newest first, including the real post content (title, subreddit, permalink, author). It records what was sent, not only how many (the counts are in monitor health). Every delivered item also carries `payload.items[].enrichment`: a `relevance.score` (0-1, how much of THIS monitor's own keyword criteria the item matched; not a model's confidence), a `sentiment` (`polarity` -1 to 1 plus a positive/negative/mixed/neutral `label`), and an `intent.tag` (question, recommendation_request, complaint, promotion, praise, or discussion). All three are deterministic keyword, lexicon and rule heuristics computed at no extra cost; each carries its own `method` field and none of them is a machine-learning or LLM call. Without `id`, the history aggregates across every monitor on the account.

Per-monitor health: active state, poll cadence, when it last matched something, and delivery counts for the last 24h (`delivered_24h`, `failed_24h`, `suppressed_24h`), plus whether its delivery ceiling has been hit (`ceiling_reached`) and what that ceiling is (`daily_delivery_ceiling`). `suppressed_24h` COUNTS TWO DIFFERENT THINGS AND `suppressed_breakdown` SPLITS THEM: `ceiling` (the monitor's daily cap was reached) and `stale` (the item was already older than the freshness window when first seen, so it was withheld rather than delivered as if it were new). A stale withhold is the usual reason a monitor's delivered count sits far below its matched count with no error anywhere; it is the freshness gate working as intended, not a failure or a plan limit, and retrying cannot recover the items. `ceiling_reached` is the field that indicates the daily cap was hit, and a stale withhold does not set it. When `suppressed_breakdown.resolved` is false the split does not add up to the total and `unresolved_reason` says why; `ceiling_reached` stays conservative in that case rather than being cleared. THOSE COUNTS COVER ONLY POSTS THAT WERE FETCHED. A post that was not fetched was not matched and leaves no row behind, so it is absent from all three counters; zeros there mean no matches were recorded, not that nothing was missed. `coverage_24h` is the separate field that speaks to fetching. Its `status` is `complete` (every poll reached the point where the previous poll finished), `degraded` (at least one poll was truncated and posts were lost unrecoverably; detail in `gaps[]`, `posts_in_window_at_least` and the estimated `posts_missed_estimate`), `partial` (nothing found, but not every kind of loss was checked; detail in `unobserved_events`), or `unknown` (the check could not be run at all; detail in `reason`). `unknown`, `partial` and a null count each mean the question went unanswered. `coverage_24h` is fed by the poll log and covers BOTH ways a poll loses posts unrecoverably…

Lists every monitor on the caller's account, with each one's filter, active state, and cadence, plus a `slots` object ({used, total, tier}) showing how many monitor slots are purchased vs in use. Reading the list requires no active plan (a lapsed subscription shows an empty or paused list, not an error). A null `webhook_ids` is the default and means matches go to EVERY active webhook on the account, the normal healthy state, not a monitor without a destination; a non-empty array narrows delivery to those webhook ids. Where a monitor's matches actually went is recorded per delivery, as the resolved `webhook_id` on each delivery row.

Deletes a monitor. There is no undo endpoint: it stops matching immediately, its slot is freed for a new monitor, and it disappears from the monitor list. Its past deliveries are NOT erased; they remain queryable in the delivery history (both by monitor id and in the aggregate, no-id view) indefinitely. Returns 404 `monitor_not_found` if the id does not exist or is not on this account.

Updates an existing monitor: pauses or resumes it (`active`), changes its poll interval (`cadence_s`), switches between posts and comments (`kind`), replaces its filter entirely, or re-targets which webhooks it delivers to (`webhook_ids`). Any filter field (subreddit, q, kind, domain, etc.) REPLACES the whole filter: it does not merge with the existing one, so a field absent from the request is cleared, and a request without `kind` reverts the monitor to posts-only. `webhook_ids` likewise REPLACES the monitor's targeting outright (an empty array clears back to every active webhook); a request without it leaves the existing targeting untouched. A request with only `active` and/or `cadence_s` changes only those. Returns 404 `monitor_not_found` if the id does not exist or is not on this account, or 400 `webhook_not_found` if a `webhook_ids` entry is not on this account.

Registers a delivery target for monitors to send matches to. Requires an active monitoring plan (a webhook with no plan could not receive anything). Returns the webhook with its signing `secret` SHOWN ONCE: the webhook list does not return it again. HTTPS only; the URL is re-validated (including a fresh DNS check) at every delivery, not just at creation.

Permanently deletes a webhook. A monitor still pointing at it fails to deliver until it is repointed at a different webhook: deletion does NOT cascade-delete or pause the monitors using it. Cannot be undone. Returns 404 `webhook_not_found` if the id does not exist or is not on this account.

Lists every webhook registered on the caller's account. The signing secret is not included; it is shown once, at creation.

Sends a one-off test delivery to a registered webhook (rate-limited to 10/min), confirming it is wired up correctly before a real match arrives. The test payload is formatted by the webhook's `kind`, the same way a real delivery would be. On failure the response carries `reason` and `status`, plus `hint`, a sentence naming the fix (most often that the target's `kind` does not match its host, which no test can succeed through), and `detail`, a bounded, sanitised copy of what the destination itself replied. `hint` carries the remedy; a bare `reason` such as `http_error` with a 400 names no field, no value and no remedy. Returns 404 `webhook_not_found` if the id does not exist or is not on this account, or `webhook_url_rejected` if the URL fails re-validation (e.g. now resolves to a private address).

Fetches a single Reddit post by its id. Returns the full post object (title, author, score, text, permalink, subreddit, url). Example: id='abc123' (the base-36 id, no t3_ prefix).

Fetches a single post and its comment tree by permalink. Returns the post plus threaded comments (author, body, score, replies) and an `after` cursor. The `permalink` is the one carried by any post result. Size a big thread with the three knobs: `limit` caps top-level comments (1-500, default 100), `depth` caps reply depth (1-10; `depth=1` is top-level only; absent is the full tree) and `sort` orders them (confidence = Reddit's best, top, new, controversial, old, qa). `limit=20, depth=1, sort='top'` reads the twenty best top-level comments and nothing below them, which keeps a 2,700-comment thread readable. `meta` echoes limit_used, depth_used and sort_used.

Every other Reddit post that shares this post's link: the list Reddit shows on a post's "other discussions" tab, across all subreddits, so every conversation about one article, video or product page can be read, not only the first thread found. Returns the original `post`, `duplicates` (up to 100 in one read, not paged, `after` is null) and `available` (how many Reddit returned). A made-up or removed post id is a 404 NOT_FOUND. A text post usually has none.

Is a post still publicly visible, or did it quietly stop being so? A removed Reddit post still returns when fetched by id, so the post alone does not answer this. This fetches the post and then one page of its author's submitted listing and compares them. Returns a verdict of live, not_visible or undecidable, a plain-language reason, and a confident flag. By design it does not say WHY a post is not visible: a moderator removal, an admin removal, a spam filter and an author who has hidden their history are indistinguishable from outside. undecidable is a real answer, not a failure. When the post resolves but the author listing read fails, the answer is still returned as undecidable with checked.author_listing false and checked.listing_error naming why (upstream_unavailable or upstream_timeout: our read was refused, not billed; listing_unavailable: Reddit answered the listing with 403 or 404, billed). Two upstream calls, billed as one $0.004 dual read.

Cancels a scheduled post or comment by its id, while it has not run yet. Returns `cancelled`, the `action` and a `message`. An action that was still scheduled comes back with cancelled true: it will not run and is not charged. An action that already ran, or is running, comes back with cancelled false and its current status, and nothing changes. 404 NOT_FOUND when the id is not a scheduled action on this account. Free.

Schedules a Reddit post or comment to be made later as the connected account, at `run_at` (60 seconds to 30 days ahead). At that time the stored request runs through the same path a live post submission or comment takes, as the Reddit session connected when it runs, so a session logged out in between makes the run fail without a charge. A public action on Reddit under the customer's name, marked as a write so a client can ask before it runs; a subreddit's rules decide whether a post stays up. Due actions are picked up every 30 seconds and run one at a time, normally within about a minute of `run_at`. A failed run is not retried: it is recorded as failed with Reddit's reason. Up to 100 actions can wait per account (409 SCHEDULE_LIMIT_REACHED past that). Scheduling is free; a run that succeeds is billed at the write rate to this API key, and a failed or cancelled one is not charged. With no connected session it answers 400 SESSION_NOT_CONNECTED. Returns 201 with `action`: `id`, `type`, `status` (scheduled), `run_at`, the stored `request`, `created_at`, `finished_at`, `result`, `error` and `billed`.

Lists this account's scheduled posts and comments, newest first. Returns `actions` and `count`. Each action carries `id`, `type`, `status` (scheduled, running, succeeded, failed or cancelled), `run_at`, the stored `request`, `created_at`, `finished_at`, `result` (what the post or comment returned, when the run succeeded), `error` (`code`, `message` and `http_status`, when the run failed) and `billed`: true for a run that succeeded, false for one that failed with an answer or was cancelled, null when the outcome was not confirmed (error EXECUTION_UNCONFIRMED or EXECUTION_INTERRUPTED, where the post or comment may still have been made and charged). Free.

Searches Reddit posts across all of Reddit or within one subreddit. Returns matching posts with author, score, comments, permalink, and an `after` cursor. `subreddit` scopes the search to one community. Optional advanced filters narrow the results by minimum/maximum score, comment count, media type, and post flags, with an optional re-sort of the page. Filters apply to the returned page, so a filtered response carries a `meta` object with page-completeness counts, and the next page comes from `after`. SORT BEHAVIOUR, measured 2026-09-11: `top`, `new` and `comments` order the MATCHING set by score, date or comment count alone, and Reddit matches loosely (image OCR, comments, and the word 'reddit' is in almost every big post), so a generic multi-word query with sort='top' and no subreddit returns the site-wide viral listing, not the topic. Even a distinctive term is ranked by score alone (q='pgvector' sort='top': 1 of 5 results was about pgvector, the rest were large posts that mention it once). Best match then highest score comes from sort='relevance' with a large `limit`, where sort_type='score' re-orders that returned page (it does not reach past the page); a quoted phrase (q='"rust vs go"') or a `subreddit` scope also narrows the matching set. Example: q='rust vs go' sort='relevance' t='year' limit=100 sort_type='score'.

Searches Reddit by COMMENT text. Reddit's comment search matches the keyword against comment bodies but returns the PARENT POSTS, not the individual comments, so each result is a post whose discussion mentions the query, carrying that post's title, selftext, score, and comment count. It surfaces threads where a topic comes up in the replies, which a post-title search misses. Reddit does not expose which specific comment matched or its text, so the results are posts, not comment bodies. Example: q='best mechanical keyboard' sort='relevance' t='year'.

Searches for subreddits (communities) by name or topic. Returns matching subreddits with title, subscriber count, description, and NSFW flag. Example: q='machine learning'.

Searches Reddit posts filtered to media (images, video, gifs). Returns media posts with the media URL/type, author, score, and the post url. `kind` narrows the results to one media type. Example: q='aurora borealis' kind='image'.

Searches for Reddit users (redditors) by name or keyword. Returns matching accounts with username, karma, and account age. Example: q='spez'.

Whether a Reddit session is connected for this account: `connected`, the Reddit username, `status` (active, or dead after Reddit rejected it), and when it was first stored, last updated and last used. The cookies are not returned. Free.

Creates a Reddit watch from a plain-words description in one call: the description is compiled into a monitor filter, the account's own plan capabilities are read, the monitor is created, and an HTTPS delivery target given in `deliver_to` is registered, pointed at this monitor and test-fired. The compiler reads subreddit names written as r/Name, quoted phrases as keyword terms (two or more become an any-of set), 'comments' or 'posts and comments' as the match kind, terms after 'except' or 'ignoring' as exclusions, and 'at least N upvotes' as a score floor; everything it derived comes back in `understood` and `compiled_filter`. A description naming neither a subreddit nor a keyword is refused before any request is sent, because a monitor is anchored by one or the other. On an account whose plan carries no subreddit-scoped watches, a description that names subreddits and also carries a keyword is built over every subreddit instead, and the swap is reported in `notes`. Monitor and webhook calls are not metered. The result carries the created monitor, the delivery target and its test outcome, and the account's current slot and capability figures.

Submits a new post to a subreddit as the connected account: a text post (kind self) or a link post (kind link). A public action on Reddit under the customer's name, marked as a write so a client can ask before it runs; a subreddit's rules decide whether the post stays up. Billed at the write rate.

Fetches a subreddit's public metadata by name (Reddit's /r/<name>/about data). Returns the subreddit's title, public description, subscriber count, active-user count, creation timestamp, type, and NSFW flag. Example: name='python'.

Streams the NEWEST comments across an entire subreddit (Reddit's /r/<name>/comments feed), not one post's thread. Returns comments with body, author, score, subreddit, the parent post link, and timestamp, plus an `after` cursor. Repeated calls surface new comments in a community as they are posted. Example: name='python'.

Lists a subreddit's post (link) flair templates by name: the flairs a new post in that community can carry. Returns `subreddit`, `count` and `flairs`, each with `id` (the value a post submission takes as flair_id), `text`, `editable` (true when a custom flair_text is accepted with that id), `type` (text or richtext), `background_color`, `text_color`, `css_class`, `mod_only`, `max_emojis`, `allowable_content` and `richtext`. Many subreddits remove a post that has no flair. Reddit lists flairs only to signed-in accounts, so the read runs as the Reddit session connected for this API key; with none connected it answers 503 SESSION_REQUIRED before Reddit is asked, and that answer is not charged. A moderator's session sees every template, mod-only ones included; any other account sees the templates it can post with, listed with mod_only false. A subreddit with no post flairs returns an empty list. Billed at the read rate, including a 403 or 404 from Reddit. Example: name='SaaS'.

Fetches a subreddit's moderator team by name (Reddit's /r/<name>/about/moderators data). Returns a `moderators` list, each with `name`, `id`, `mod_permissions`, `flair_text`, and `added` (when they joined the mod team). Example: name='python'.

Lists posts from a subreddit by sort order: newest, hot, top of a time window, rising, controversial or best. Returns post title, author, score, comment count, and permalink, plus an `after` cursor for paging. When `after` comes back null the response carries `listing_status`: `complete` means no older posts and is only claimed when the whole run came back in under one page, `truncated` means Reddit's cap cut the listing off, and `unknown` means completeness could not be established. A busy feed that Reddit stops serving reports `unknown`, not `complete`. Example: subreddit='programming' sort='top' t='week'.

Fetches a subreddit's posting rules by name (Reddit's /r/<name>/about/rules data). Returns a `rules` list, each with name, description, what it applies to (posts, comments, or all), violation reason, priority, and creation date, plus a `site_rules` list of Reddit's site-wide rules. Example: name='python'.

Gets the TOP posts of a subreddit for a time window, the highest-scoring posts of a community. Returns posts with score, author, comments, and permalink plus an `after` cursor. Example: name='science' t='month'.

Fetches a subreddit's wiki page by name and page (Reddit's /r/<name>/wiki/<page> data). Returns a single object with `content_md` and `content_html`, a `may_revise` flag, and the last revision (`revision_id`, `revision_date`, `revised_by`, `reason`). A wiki commonly holds a community's rules or FAQ. The page may be multi-segment, for example index, rules, or config/sidebar. Example: name='python', page='index'.

Browses Reddit's default front-page set of subreddits, with no keyword. Returns a `subreddits` list (each with name, title, subscriber count, description, type, and NSFW flag) plus an `after` cursor for paging.

Browses the newest subreddits, the communities most recently created, with no keyword. Returns a `subreddits` list (each with name, title, subscriber count, description, type, and NSFW flag) plus an `after` cursor for paging.

Browses the most-subscribed, trending subreddits right now, with no keyword. Returns a `subreddits` list (each with name, title, subscriber count, description, type, and NSFW flag) plus an `after` cursor for paging.
