Chat completions - metered (pay
OpenAI-compatible chat completions priced from the request itself: the 402 quotes this exact body, from $0.001, and a buyer on the upto scheme settles the tokens actually used under that quote. Use it when an agent sends large or variable prompts and wants to pay for what it sends, not a flat tier.
