# Rate limits

> How often you can call each route.

Each API key may call each route **10 times a minute**. The allowance refills evenly: one call every 6 seconds, up to 10 saved.

Every answer says where you stand:

| Header | Meaning |
| - | - |
| `X-RateLimit-Limit` | Calls allowed per window: `10`. |
| `X-RateLimit-Remaining` | Calls left now. |
| `X-RateLimit-Window` | The window, in seconds: `60`. |

Past the limit, the API answers `429` with a `Retry-After` header, in seconds:

```json theme={null}
{
  "statusCode": 429,
  "message": "RATE_LIMIT_EXCEEDED",
  "limit": 10,
  "windowSeconds": 60,
  "retryAfterSeconds": 6,
  "traceId": "…",
  "timestamp": "2026-11-03T09:41:12.000Z",
  "path": "/v1/find-email"
}
```

Wait `retryAfterSeconds`, then try again. Each route has its own allowance, so a busy `find-email` doesn't slow `verify-email`.
