Search the Meta Ad Library for a company's ads through Facebook's sanctioned Graph API and return ONE FLAT ROW PER AD with creative text, headline, delivery dates, the Meta surfaces it ran on and Meta's permanent snapshot URL for the rendered ad. COVERAGE IS NOT UNIVERSAL: the Ad Library holds all ads only in the EU and only political and issue ads elsewhere, so a commercial advertiser outside the EU is legitimately absent and every row carries a coverage note saying what the search could have found. Requires the CALLER's own Meta app access token. Impressions and spend exist for political ads only and arrive as bands, so a null there is not zero spend. Read only; requires an APIFY_TOKEN and consumes Apify credits per call.
