# Rate limits for the FastPix API

> The FastPix API enforces per-endpoint rate limits at the workspace and organization level, returns X-RateLimit headers, and responds with HTTP 429 when you exceed a limit.

The FastPix API rate limits are now documented. Each request is counted against two limits at once, your workspace and your organization, and is tracked per endpoint, so a burst on one endpoint does not use up another's allowance.

What's new for customers:

* **Per-endpoint limits:** by default, each endpoint allows a burst of 100 read (`GET`) and 20 write (`POST`, `PUT`, `PATCH`, `DELETE`) requests per workspace, with an organization-wide ceiling of 250 reads and 50 writes. Each bucket refills at a sustained 1 request per second.
* **Rate-limit headers:** successful responses include `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset`, so you can slow down before you hit a limit.
* **Clear 429 responses:** when you exceed a limit, the API returns HTTP 429 with a `Retry-After` header and a structured error body.

See [Rate limits](/docs/api-reference/rate-limits) for the full reference, including best practices for handling 429 responses.
