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.
