When to use this

Typeahead search over advertisers in the Ad Library, like the search box on facebook.com/ads/library. Returns up to about 15 matches, no pagination.

Parameters

All parameters go in the query string.

Example request

curl "https://api.lurkapi.com/v1/facebook/adLibrary/search/companies?query=nike" \
  -H "x-api-key: YOUR_API_KEY"

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

import os
import requests

res = requests.get(
    "https://api.lurkapi.com/v1/facebook/adLibrary/search/companies",
    params={
        "query": "nike",
    },
    headers={"x-api-key": os.environ["LURKAPI_KEY"]},
    timeout=60,
)
data = res.json()
if not data["success"]:
    raise RuntimeError(f"{data['code']}: {data['error']}")
print(data["searchResults"])

Example response

A real response from this endpoint, captured from the live API and trimmed to a couple of items. Strings over 96 characters (mostly signed media URLs) are cut short and end in ….

{
  "success": true,
  "credits_remaining": 996,
  "credits_charged": 1,
  "searchResults": [
    {
      "category": "Sportswear Store",
      "country": null,
      "entity_type": "PERSON_PROFILE",

Response fields

Every field of a successful response. [] marks a list: a[].b is the b of each item in a. nullable fields can be null; optional fields can be missing.

Caching and freshness

Responses are cached for up to 1 day, so a repeat call within that window can return the same data. It still costs 1 credit.

Errors

Errors return { success: false, error, code, docs } with the HTTP status below. Validation errors, 401/402/429 rejections and 5xx failures are free; not_found is charged (how charging works). All error codes.

Use it in Claude

Once LurkAPI is connected to Claude, this endpoint is the facebook_search_companies tool. Ask in plain English, for example:

Use LurkAPI's facebook_search_companies with query "nike" and summarize what you find.

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

{
  "query": "nike"
}

Tool results skip nulls and empty lists to save tokens.
