Overview
x402 listing doctor for sellers: why a paid endpoint gets no buyers. Runs the x402 preflight, Coinbase's CDP validator, and presence checks in the CDP Bazaar and 402index, then returns concrete fixes: 402 before input validation, Bazaar metadata, description over 500 chars or instruction-like, slow or sleeping host, no settled sale yet. Input: endpoint URL, optionally 'POST <url>'. Deterministic, no LLM.
