## When credits are charged

Credits are charged only on successful responses (HTTP 200). Failed requests, validation errors, and rate limit rejections do not consume credits.

## Monitoring your balance

Your balance and consumption history are available in your API Workspace under **Usage**. Your remaining balance is also returned in the `X-Credits-Remaining` response header on every successful request.
