Spacex Rate Limits

The community SpaceX REST API enforces a per-IP request-rate limit of approximately 50 requests/second at the hosted endpoint (https://api.spacexdata.com). All GET responses and POST /query responses are also cached server-side via Redis (launches 20s; capsules / cores / launchpads / landpads / crew / ships / payloads 5min; dragons / rockets 24h). Throttled responses return HTTP 429. Self-hosted deployments do not enforce any rate limit by default.

Spacex Rate Limits is the machine-readable rate-limit profile for SpaceX (Community API) on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests_per_second and seconds.

The profile also includes response codes documented for throttled.

Tagged areas include Rate Limiting and Caching.
