API 429 / rate limit exceeded

Every response carries X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset (Unix epoch).

On a 429, sleep until the Reset epoch and retry. The official SDKs handle this automatically.

If you hit the limit regularly, request a higher quota via your CSM or contact-sales. Bulk-load endpoints already have a separate (higher) limit.
