Rate limits

How public API request limits, headers, and retries work.

View as Markdown

Authenticated public API requests are rate limited per workspace. Requests made with any valid key for the same workspace share the same bucket, so creating more keys does not increase the limit. The public OpenAPI schema at /api/v1/openapi.json is not rate limited.

Current default limits:

WindowLimit
Per minute60 requests
Per day1,000 requests

Response headers

Successful limited requests include headers for the currently binding window:

HeaderMeaning
X-RateLimit-LimitThe request limit for the active window
X-RateLimit-RemainingRequests remaining in that window
X-RateLimit-ResetUnix timestamp when the window resets

When you hit the limit

If either the minute or day window is exhausted, the API returns 429 TOO_MANY_REQUESTS:

json
{
  "error": {
    "code": "TOO_MANY_REQUESTS",
    "message": "Rate limit exceeded"
  }
}

The response also includes Retry-After, in seconds. Wait at least that long before retrying.

Client guidance

  • Treat Retry-After as authoritative for 429 responses.
  • Add backoff and jitter when retrying automated jobs.
  • Cache stable reads, especially project configuration and metadata lists.
  • Paginate list requests instead of making many narrow repeated calls.
