GEThttps://api.lurkapi.com/v1/facebook/adLibrary/search/ads

When to use this

Use it to see how a whole market advertises: the angles, offers and formats that keep running. For one advertiser's ads, use company ads (facebook_company_ads) instead. Stopped ads are included unless you pass status=active.

It searches every ad in Meta's Ad Library, the same as typing into the search box at facebook.com/ads/library. Filter by country, status, format, language and date range. The most-seen ads come first by default.

Pagination. The first page has up to 30 ads and searchResultsCount, the estimated total. For more, pass cursor back with the same filters. Later pages have up to 10 ads (Facebook's own page size), and searchResultsCount is null there. cursor is null on the last page.

Example request

Copy one and replace YOUR_API_KEY with your API key (get one free). The code versions read the key from the LURKAPI_API_KEY environment variable instead.

curl "https://api.lurkapi.com/v1/facebook/adLibrary/search/ads?query=running+shoes&country=US&status=active" \
  -H "x-api-key: YOUR_API_KEY"

Paste it into a terminal, with your key in place of YOUR_API_KEY.

const params = new URLSearchParams({
  query: "running shoes",
  country: "US",
  status: "active",
});
const res = await fetch(`https://api.lurkapi.com/v1/facebook/adLibrary/search/ads?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_API_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data.searchResults);

Pagination

Results come in pages. For the next page, repeat the call with the same parameters and add the response's cursor as cursor. On the last page, cursor is null. Each page costs 1 credit.

The first five pages, in JavaScript

let cursor = null;for (let page = 1; page <= 5; page++) {const params = new URLSearchParams({ query: "running shoes", country: "US", status: "active" });if (cursor) params.set("cursor", cursor);const res = await fetch(`https://api.lurkapi.com/v1/facebook/adLibrary/search/ads?${params}`, {headers: { "x-api-key": process.env.LURKAPI_API_KEY },});const data = await res.json();if (!data.success) throw new Error(`${data.code}: ${data.error}`);console.log(data.searchResults);cursor = data.cursor;if (!cursor) break; // last page}

Cost and freshness

Each call costs 1 credit. Calls turned away before they reach the platform (invalid parameters, a key or balance problem, a rate limit) are free, and so are 5xx errors. A not_found is charged, since the platform was checked. How charging works.

Answers are cached for up to 30 minutes. A repeat call within that time can return the same data, and costs the same.

Errors

A failed call returns success: false, an error message, a code your program can check, and a docs link. These are the errors this endpoint can return. All error codes.

Status	Code	Meaning
401	`missing_api_key`	No API key was sent. Put it in the `x-api-key` header.
401	`invalid_api_key`	This key doesn't exist or was revoked.
402	`insufficient_credits`	Not enough credits for this call. Buy a pack, or wait for tomorrow's free top-up.
402	`over_max_credits`	This call would cost more than the `max_credits` you set. The error says what it needs; raise `max_credits` to allow it. Not charged.
403	`account_suspended`	This account is suspended. Email support@lurkapi.com. Not charged.
405	`method_not_allowed`	Endpoints only take `GET`, with parameters in the URL.
429	`rate_limited`	Too many calls in a short time. Wait as many seconds as the `retry-after` header says, then retry.
500	`internal_error`	Something broke on our side. Retry. Not charged.
502	`upstream_error`	The platform didn't send a usable answer. Retry. Not charged.
503	`upstream_busy`	All our connections to the platform are busy. Retry in a few seconds. Not charged.
504	`upstream_timeout`	The platform took over 30 seconds to answer (90 for web pages). Retry. Not charged.

Use it in Claude

Connect LurkAPI to Claude and ask in plain English. This endpoint is the facebook_search_ads tool. For example:

Ask Claude

Use LurkAPI's facebook_search_ads tool with query "running shoes", country "US", status "active", then summarize what you find.

Claude calls facebook_search_ads with arguments like these, and each call costs 1 credit:

Tool arguments

{"query": "running shoes","country": "US","status": "active"}

To save tokens, tool results leave out empty fields, keep one URL per image or video, and give transcripts as plain text unless you pass timestamps=true. A result over 45,000 characters comes in parts. Its _note gives the offset for the next part, and later parts are free for 15 minutes. Pass trim=false for the full response.
