x402 Payment Endpoint Registry Has 14,085 Listings, but 10,508 Are From One Suspended Domain

A cataloguing effort tracking x402 payment endpoints found that 10,508 of the 14,085 registered endpoints belong to a single suspended provider, leaving just 3,577 genuine entries as of July 2026. Of those, only 2,131 pass verification checks, while 1,446 — roughly two in five — fail. The catalogue probes each endpoint every 10 minutes via automated checks, testing for responsiveness, valid 402 responses, well-formed payment challenges, and price accuracy. The verification is considered critical because x402 requires an AI agent to pay before confirming whether a response is useful, meaning a dead endpoint costs real money with no recourse. Testnet endpoints, which return valid responses but cannot process real transactions, are kept in the catalogue but excluded from discovery results to prevent misdirected payments.
