live

OpenAI-compatible chat completions gateway — standard /v1/chat/completions path and request shape, model chosen in the body: any gpt-* chat model (not Claude/embeddings), each at its own price. Priced per model, $0.005–$0.65 per call in USDC via x402, no API key: POST unpaid and the 402 quotes your model's exact price. Supports response_format json_object. GET /v1/models (free) lists every model …

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
