# Rate limits

600 requests/minute per API key across the whole surface. Over the line:

```http theme={null}
HTTP/1.1 429 Too Many Requests
Retry-After: 37

{ "name": "rate_limited", "code": "rate_limited",
  "message": "Rate limit exceeded.", "fix": "Back off and retry." }
```

Send-heavy workloads should fan out across project-scoped keys; webhook
deliveries to *your* endpoints retry separately (Effect schedule, 5 attempts,
jittered backoff) and never consume your quota.
