# Rate limits

Per-key request buckets and the RateLimit headers.

| Bucket                     | Limit          |
| -------------------------- | -------------- |
| Requests per key           | 600 per minute |
| Money-moving POSTs per key | 60 per minute  |

Every response carries `RateLimit-Limit`, `RateLimit-Remaining` and `RateLimit-Reset` (seconds) for the tightest bucket; `429` [`rate-limited`](/errors#rate-limited) adds `Retry-After`. Back off exponentially with jitter and honour `Retry-After`. Each key has its own buckets; rate-limit hits per key are visible in the console ([Integration and usage](/docs/integration-usage)).
