Overview
Which x402 API should I call? Give need=<task>; get the top-k paid endpoints: url, method, price, network, 30-day on-chain buyers, live-402 probe, risk flags and score, ranked by relevance x log(1+buyers) x recency x liveness over the x402-list.com catalog (CC BY 4.0) and sellers' own 402s. Own listings use the same formula. No match = 404, not charged.
