OpenAI gpt-6.1-sol and 25 more models via openai.mm.family
OpenAI gpt-6.1-sol and 25 more models via openai.mm.family
POST /x402/v1/chat/completions with a standard OpenAI chat-completions JSON body; pick model from GET /x402/v1/models. Each model has its own endpoint too: POST /x402/v1/models/<key>/chat/completions with the same body (model optional). The first unpaid call returns 402 with the exact USDC quote - pay via x402 and retry with the same body. The quote charges the input plus 10% of max_tokens as output; the model may use all of max_tokens. Tiers: omit service_tier for the model's default (Flex where available, else Standard); send default for Standard or fast for OpenAI Fast mode; GET /x402/v1/models lists each model's tiers. On reasoning models, temperature must be 1. Append :<level> to a model key to pin reasoning_effort, e.g. gpt-6-sol:high; levels per model are in GET /x402/v1/models. Reasoning tokens are billed as output and are spent before visible text: for short answers send max_tokens of at least 128, or use a low level (gpt-5-mini:minimal, otherwise :low); an answer with no visible output is not charged. Non-chat: POST /x402/v1/embeddings, /x402/v1/images/generations and /x402/v1/audio/speech with standard OpenAI bodies (per-model paths under /x402/v1/models/<key>/...); images need explicit size and quality; see modalities in GET /x402/pricing. See GET /x402/pricing for rates and rules.
