Does Facebook have an API?
Yes. Meta provides Graph API, Marketing API, and related products for Pages, ads accounts, and assets you manage or that grant your app permission. Public-data APIs cover public pages, posts, groups, Marketplace helpers, and Ad Library results for research and enrichment.
Official Meta / Facebook APIs
Graph API and Marketing API are built around Facebook Login, app review, and tokens for assets you own or administer. Typical uses: publishing, insights for your Pages, messaging, and ads reporting.
They are a poor fit when the job is competitor page monitoring, public group research, or Ad Library creative pulls for advertisers that never connected to you. Owner tokens do not turn into a general competitor research feed.
Public-data Facebook APIs
Social Fetch includes Facebook in the same 17-platform catalog (137 marketplace ops). Routes cover public profiles and pages, posts and reels, group content, Marketplace helpers, transcripts where supported, and Ad Library search.
You authenticate with an API key and get the shared Social Fetch envelope, so Facebook rows sit next to Instagram in the same warehouse schema.
Ad Library without owning the Page
Facebook's distinctive public surface is Ad Library. Competitor creative monitoring usually needs advertiser and ad lookups without admins access to anyone's ads account. Social Fetch Ad Library routes cover that research path; Marketing API still owns ads account management and owner insights.
Try a search on /tools/facebook-ad-library before you integrate. Managing content, insights, or ads for assets you control? Use Meta's official APIs. Research, group samples, Marketplace helpers, or Ad Library monitoring? Use a public-data API such as Social Fetch. Ad Library and list routes may differ in credits from a single page GET.
FAQ
Can Graph API look up any public Facebook page?
Access is scoped to permissions and assets your app is authorized for. Arbitrary public enrichment is not the primary design of Graph API.
Does Social Fetch replace Marketing API?
No. It covers public lookups and Ad Library-style research. If you need ads account management or owner insights, keep Meta's APIs.
Where do I try Facebook Ad Library without code?
Use /tools/facebook-ad-library, then /platforms/facebook and the API docs for production.
Do Facebook lookups cost credits?
Yes on Social Fetch metered routes. Ad Library and list routes may differ from a single page GET. Check each docs page.
