# Balance

Check your available credits and rate limits.

Returns the available and reserved credits plus the account's rate-limit and concurrency allowance.

### Credits and limits

`available` is what you can spend, `reserved` is what in-flight solves hold, and `total_consumed` is what the account has spent. `rate_limit_per_second` and `max_concurrent_solves` cap how fast and how many solves can run at once.

### Errors

A missing or invalid API key returns `401 invalid_api_key`; an account that does not exist returns `404 resource_not_found`.
