How this service works
API Gateway: OpenAI API
Output
The standard OpenAI API JSON response for the proxied endpoint — e.g. a chat completion object with choices, usage stats, and model metadata — identical to what the OpenAI API itself would return, after deducting $0.005 USDC for the gateway call.
Example use cases
Example prompt
“Send a chat completion request to OpenAI's GPT-4o model asking 'What are the three laws of thermodynamics?' — pay per call using USDC via the httpay.xyz x402 gateway instead of using my own OpenAI API key.”
Technical details
Endpoint

Use this endpoint when you want to call the OpenAI API without managing your own OpenAI API key, when you want pure pay-per-call billing in USDC on Base, or when building an agent that needs to access OpenAI capabilities with crypto-native micropayments via the x402 protocol.

- Invalid or unsupported OpenAI path returns 404 or 400
- Malformed request body causes 400 Bad Request from upstream OpenAI
