Frequently asked questions
What is the Facebook Ad Library API?+
The Facebook Ad Library API is a REST API from Captapi that returns public Facebook Ad Library data as clean, structured JSON. It covers 5 endpoints — Search, Company Ads, Search Companies, Ad Details, Ad Copy — behind one Bearer API key, with no OAuth flow and no infrastructure to build or maintain.
What data can I get from the Facebook Ad Library API?+
Search Meta Ad Library creatives, advertisers, and company ads for competitor research. Each endpoint is a single GET request that responds with predictable JSON fields, so the data is ready for dashboards, AI pipelines, and automations.
Do I need a Facebook Ad Library developer account or OAuth?+
No. You only need a Captapi key (capt_live_...), sent as an Authorization: Bearer header. The same key works across all 32 platforms Captapi supports. We handle proxies, rate limits, retries, and parsing for you.
How much does the Facebook Ad Library API cost?+
Facebook Ad Library endpoints cost between 2 and 2 credits per call, depending on the endpoint. New accounts start with 100 free credits (no credit card). Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d.
Can AI agents use the Facebook Ad Library API?+
Yes. Every Facebook Ad Library endpoint is exposed as a tool in the official MCP server (@captapi/mcp) for Claude, Cursor, and VS Code, and is also available through the @captapi/cli CLI, an n8n community node, a Make.com app, and an Apify Actor.
Is the Facebook Ad Library API suitable for production use?+
Yes. It is a stable REST API with predictable JSON, automatic retries, and upstream fallbacks. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Only successful responses consume credits — failed or empty results are never charged.
