Frequently asked questions
What is the Ad Library API?+
The Ad Library API is a REST API from Captapi that returns public Ad Library data as clean, structured JSON. It covers 12 endpoints — Facebook Search, Facebook Company Ads, Facebook Search Companies, Facebook Ad Details, Facebook Ad Transcript, TikTok Search, and more — behind one Bearer API key, with no OAuth flow and no scrapers to build or maintain.
What data can I get from the Ad Library API?+
Search public Meta, TikTok, Google, and LinkedIn ad libraries for competitor creative intelligence. 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 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 29 platforms Captapi supports. We handle proxies, rate limits, retries, and parsing for you.
How much does the Ad Library API cost?+
Ad Library endpoints cost between 17 and 70 credits per call, depending on the endpoint and how many results you request. New accounts start with 100 free credits (no credit card), and repeat calls are served from a 24-hour cache for 0 credits.
Can AI agents use the Ad Library API?+
Yes. Every 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 Ad Library API suitable for production use?+
Yes. It is a stable REST API with predictable JSON, automatic retries, upstream fallbacks, and a shared 24-hour cache. Only successful responses consume credits — failed or empty results are never charged.
