```

## Parameters
This endpoint requires no query parameters. Authentication is performed via the `x-api-key` header.

- `percent_used` values may exceed 100 if top-ups or overage scenarios apply.
- `rate_limit` values are `null` for plans without rate limiting.

## Main use cases
- Monitor remaining credits in real time and trigger automated top-up workflows before exhausting your quota
- Build internal dashboards that display API consumption per team or project
- Set up alerting systems that notify your team when usage exceeds a defined threshold
- Validate API key status and expiry before running batch scraping jobs
