Api x402 offerings

One call replaces the multi-request health sequence autonomous agents repeat before acting: EIP-155 chain ID, latest block height/header and age, gas price, EIP-1559 fee direction and recommended fee, safe/finalized tips when supported, utilization and a HEALTHY/CONGESTED/STALE verdict. Covers Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis and the newly live Robinhood Chain (chain ID 4663). Live public RPC, explicit capability gaps, no guessed values.

LLM completion per call, no account and no API key: POST a prompt (or a messages array) and get the model answer as JSON. Hard caps disclosed in every response (6,000 UTF-8 bytes in, 750 tokens out on this tier). Fixed price per call, signed receipt included so the answer stays auditable. Larger tier at /x402/chat-plus.

LLM completion per call on a stronger model, no account needed: POST a prompt or messages array, get the answer as JSON. 6,000 UTF-8 bytes in, 1,200 tokens out, fixed price per call, hard caps disclosed in every response, signed receipt included. Smaller and cheaper tier at /x402/chat.

OpenAI-compatible chat completions with the model chosen server-side: omit model and the gateway routes the prompt to the top-ranked model for its task (code, reasoning, long-context, general) from a fixed eval-derived ranking, failing over automatically on provider errors. Flat price per call, 16k chars in, 1024 tokens out, streaming supported. Use it as a drop-in OpenAI base_url when you want good answers without picking a model.

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.
