# Rate limits

Requests are limited per partner key and per user. Defaults are 6,000 requests per minute per
partner key and 300 per minute per user; deployment configuration can change those values.
Inspect the response's rate-limit headers and honor `Retry-After` on `429`.

Streams also have per-user and per-replica socket limits; reaching them returns
`429 stream_capacity`. Reconnect with backoff. Request limits, execution capacity and user spend
budget are separate constraints. Read the error's `reason` to distinguish them.
