# Rate limits

> 120 requests per minute per key, RateLimit and Retry-After headers.

**120 requests per minute per key.** Every response announces them, errors included:

```
RateLimit-Policy: "cle";q=120;w=60
RateLimit: "cle";r=117;t=42
```

IETF draft format `draft-ietf-httpapi-ratelimit-headers-11`: `q` the quota, `w` the window (seconds), `r` what remains, `t` seconds until reset. The older `RateLimit-Limit`, `RateLimit-Remaining` and `RateLimit-Reset` are still sent.

Beyond that: `429` with `Retry-After` (in seconds). Wait that long before retrying.
