TL;DR

Find Meta Ad Library pages by brand — name-matched, pageId for company-ads (not profileId). The Facebook Ad Library Search Companies API (Facebook Ad Library) is a single authenticated GET request to /v1/ad-library/facebook/search-companies that responds with clean JSON and costs 2 credits. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the Facebook Ad Library Search Companies API?

Search Meta Ad Library advertisers/pages by brand name. Results are relevance-filtered so query tokens must appear in the page name — off-brand pages that merely appeared near the keyword (e.g. Sukeban for q=nike) are dropped; empty beats spam. Each company returns id = pageId = advertiserId (pass to /facebook/company-ads), profileId when the facebook.com/{digits}/ URL uses a different numeric identity, vanity or numeric url, logo, and libraryUrl (ready view_all_page_id link). Chain: search-companies → companies[0].pageId → company-ads?url=. Flat 2 credits.

What you get

Name-matched ranking (exact brand first)
pageId / advertiserId for company-ads (view_all_page_id)
profileId when facebook.com/{digits}/ ≠ pageId
libraryUrl ready for Ad Library page view
Empty beats off-brand spam
