Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
find_templates Find a structured-data template ~217
Find published templates that parse a site into structured JSON instead of HTML. Pass the url you are about to fetch to see whether one already covers it — do this before writing your own extraction for a well-known site. Also searches by keyword or category. Each result shows the fields it returns and an example call; pass its reference as unblock_fetch's template argument. Free — no credit is charged.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Category slug, e.g. 'search-results', 'real-estate', 'business-directories'. Omit all filters to see the categories. |
| limit | integer | – | Maximum templates to return (default 25). |
| page | integer | – | Which page of `limit` results to return, from 1, when more templates match than fit. |
| search | string | – | Keyword matched against a template's name, reference, host and description (e.g. 'property', 'company'). |
| url | string | – | A URL you intend to fetch. Returns the templates built for that site, if any. |

get_build_guide How to build an app on UnblockingAPI ~229
Read this before writing code that uses UnblockingAPI - an app, script, scheduled job or backend that fetches web pages (a rank tracker, a listings aggregator, a price monitor, …). Returns the REST API reference for calling it with plain HTTP (no SDK), how to keep the key server-side on platforms like Lovable, Replit and Next.js, how to use templates, and complete recipes. Free. Start with topic 'api', then the recipe that fits.
| Name | Type | Req | Description |
|---|---|---|---|
| topic | string | yes | 'api': the REST API for apps: request, response, errors, timeouts, keeping the key server-side. 'fetch-tuning': getting complete pages: scrolling, waiting for content, consent walls, locations. 'temp… |

unblock_fetch Fetch a URL through UnblockingAPI ~963
Fetch a web page through UnblockingAPI's rotating residential proxies and a real browser. Useful for pages a plain HTTP fetch can't read: pages that need JavaScript, refuse automated requests, or show different content by country. Returns the page as Markdown (or cleaned HTML with format: 'html'); select narrows it to the part you need. If content is missing, fetch again with scroll_steps or wait_for. Picks the mode itself by default: a plain HTTP fetch first, and a real browser when the site blocks it or needs JavaScript. Pass a template reference to get structured JSON instead of HTML — call find_templates with the url first to see whether one exists. Costs 1 credit per successful fetch; failures are free.
| Name | Type | Req | Description |
|---|---|---|---|
| detect_ms | integer | – | Implies a browser. How long to probe wait_rules guards before falling back to wait_for. Default 800. |
| format | string | – | How the page comes back (template results are always JSON). "markdown" (default): text, headings, links and lists, a fraction of the size. "html": the cleaned markup, for attributes, custom elements… |
| fresh | boolean | – | Fetch again even if this exact fetch was made in the last 10 minutes (by default that copy is reused for free). |
| location | string | – | 2-letter country code to proxy through (e.g. 'us', 'gb', 'de'). Most countries are supported; an unsupported one is refused with the list. |
| max_age | integer | – | Accept a cached copy of the same request up to this many seconds old (0–300). Cache hits return in milliseconds and still cost 1 credit. Default 0 = always fetch fresh. |
| max_chars | integer | – | Cap on returned body characters (default 80000, max 140000). Longer bodies are cut with a note; select narrows a page to the part you need instead. |
| render | boolean | – | Omit to let the API decide (plain fetch first, a browser when blocked or when the page is an empty JavaScript shell; learned per site). true always renders with a real browser (slower, up to ~2 min w… |
| scroll_steps | integer | – | Implies a browser. Scroll down this many times before the readiness check, to trigger lazy-loaded sections. Bounded discovery, not a way to collect an infinite list. |
| select | string | – | CSS selector: return only the matching elements (e.g. 'article', 'table tr', 'shreddit-post'), in the chosen format. Re-reading a fetch with another select or format reuses the page already fetched -… |
| settle_ms | integer | – | Implies a browser. Ceiling (not a delay) on the settle wait, default 5000. Capture happens as soon as the DOM has been quiet for 500ms. Use wait_min_ms for a minimum delay; lower this to cap the wors… |
| template | string | – | Parse the page with a published template and return JSON instead of HTML. Takes a template reference like 'handle/name' — call find_templates with this url first to see whether one covers the site. A… |
| url | string | yes | The HTTP/HTTPS URL to fetch. Media and binary files are rejected. |
| wait_for | string | – | Implies a browser. When to capture: 'stable' (default — once the DOM stops changing), 'domcontentloaded' (immediately), 'networkidle', or any CSS selector (wait until it is visible, then settle). Pre… |
| wait_min_ms | integer | – | Implies a browser. Minimum delay after navigation before scrolling or checking readiness, for content that is absent from the first capture. |
| wait_rules | array | – | Implies a browser. Conditional waits for pages with several possible layouts (consent gate, interstitial, A/B variant). Each 'if' selector is probed in order for detect_ms; the first visible one wins… |
| wait_state | string | – | Condition for a CSS selector in wait_for (requires one): 'visible' (default), 'nonempty' (visible text, ignoring loading placeholders), 'hidden' (all matches hidden or gone — e.g. a spinner), 'stable… |
