FactGrid's data is freely available under the CC BY 4.0 license. Use our API to build comparison tools, dashboards, or analyses — attribution required. Rate-limited and cached at the Cloudflare edge for performance.
Entity Catalog Endpoint
Returns a catalog of all independently audited entities — slugs and names. Use this to discover available entities.
Returns a minimal catalog of all independently audited entities in the archive.
No authentication required. Use the returned slugs to fetch detailed data from the
/api/v1/entities/{slug} detail endpoint.

}Rate Limiting & Caching
Responses are cached at the Cloudflare edge for 1 hour with a 24-hour stale-while-revalidate window. There is no hard rate limit enforced via API keys — Cloudflare's built-in DDoS protection and edge caching absorb the load.

| 400 Bad Request | Malformed request or missing slug. |
