Three speeds where OpenAI offers them: Flex (half of list, default where available; may answer 429), Standard (service_tier default), Fast (service_tier fast). The quote is an upper bound from max_tokens (default 1024). Payment is taken when the first token arrives, when the answer is complete, or after 30 s if the model is still reasoning; long reasoning can take minutes after that, so use stream:true or a long client timeout. Reasoning models: temperature must be 1. Model keys take a :level suffix for reasoning_effort (levels in /x402/v1/models); reasoning tokens are billed as output, so send max_tokens >= 128 or a low level for short answers. Sheet: https://openai.mm.family/x402/pricing. Each model also has its own endpoint: POST https://openai.mm.family/x402/v1/models/<key>/chat/completions (same body, model optional).
