Which x402 API should I call?
Which x402 API should I call? API recommender / discovery for agents: describe the need in plain words; get the best x402 endpoints from the WHOLE Bazaar (36k+ endpoints, re-indexed every 6 h) ranked by relevance, real 30-day demand (unique payers, calls), recent use and price, with method, price, networks and a ready-to-send example call. Max 2 per seller, dead tunnel URLs removed. Filters: max_price, network.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
