Make your first request

Use any OpenAI-compatible SDK. Change the base URL, keep everything else. Responses include a receipt with the exact cost.

No account: send the same request to /x402/v1/chat/completions without credentials and the gateway answers 402 with the quote. Pay per request.

This model has no enabled route right now, so the request below is refused with model_unavailable until a route is enabled. Nothing is charged for a refused request.
