# Rate limits

> Request and concurrent-job limits and retry behavior.

Rate limits apply per API key, project, and account. A separate concurrency limit caps the number of jobs that may run at once.

When a limit is exceeded, the API returns:

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

Wait for the indicated delay and retry with exponential backoff. Do not retry immediately in a tight loop.
