Find the Facebook Pages that advertise under a brand or advertiser name in the Ad Library, up to 15 per call. Each Page has its ID, name, username, category, verification flag, Page likes, and the linked Instagram account with its follower count. A search for nike puts Nike (Page ID 15087023444) first. There is no paging.

Price $0.88 per 1,000 requests ($0.000875 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

AI prompt

Please help me write a data collection script with the EveryInfra Facebook Advertiser search endpoint (facebook/advertiser_search).

How the endpoint works:
- Request: POST https://api.everyinfra.com/api/v1/social with the header Authorization: Bearer <API key>. Read the key from the EVERYINFRA_API_KEY environment variable and never hard-code it.
- In the request body, set platform to facebook and action to advertiser_search, and put the parameters inside params.
- Required parameters:
  - keyword: A brand or advertiser name, such as nike. Returns the Pages that advertise under that name in the Ad Library; each id is a Page ID.
- Optional parameters:
  - limit: The most rows to return in this call, an integer from 1 to 15. The default applies when you leave it out, and a call can return fewer rows. Larger values are accepted and capped at the maximum. (default: 15)
- Returns a list of records. Main fields of each record: id, name, username, url, category, avatar_url, page_like_count, is_verified, instagram_username, instagram_follower_count, instagram_verified, country.
- Example request body:
{
  "platform": "facebook",
  "action": "advertiser_search",
  "params": {
    "keyword": "nike"
  }
}
- Price: $0.88 per 1,000 requests; failed and empty results are not charged.
- For dozens or hundreds of targets, add "mode": "async" to the body: you get a job_id at once and poll GET https://api.everyinfra.com/api/v1/jobs/{job_id} for the result.
- On 422, fix the request using the suggested parameter names and allowed values in the error; on 429 or 503, wait for Retry-After and try again.

Before writing code, ask me which targets I need, how many, which fields, and what output format I want; then confirm the plan and the rough cost with me.
