## Headers

Every keyed answer carries:

```
X-RateLimit-Limit: 600
X-RateLimit-Remaining: 587
X-RateLimit-Reset: 1763237040
```

`X-RateLimit-Reset` is a Unix time in seconds. Over a limit, the answer is `429` with `Retry-After` in seconds.

## Staying under

- Use the [registry](/developers/guides/registry) cursor instead of re-reading `/coins`.
- Send `If-None-Match` (see [Freshness and caching](/developers/principles/caching)).
- Batch: one `/coins/check` call answers for 500 mints.
