Rate limits for the FastPix API

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 for the full reference, including best practices for handling 429 responses.
