Published 2026-09-28. Full catalogue scan of 2026-09-27: 17,513 x402 resources across 2,023 hosts.
17,513 pay per call resources across 2,023 hosts. 16,487 return a well formed 402 that could settle, 895 cannot be paid with either GET or POST, 73 are malformed, 52 were unreachable. 16,488 carry a price in this scan, median 0.01 USDC. A PAYABLE verdict means the challenge is well formed and, on Solana, the destination account exists. It is not a claim about delivery, quality or honesty.
Base carries 16,273 payable resources, Solana 5,375, then Polygon 2,545 and Arbitrum 2,279.
Against the 20 September scan, 4,173 resources appear and 1,603 are absent. Of the 4,173, 528 had been seen in an earlier scan and came back, 3,645 are seen for the first time. Absent does not mean dead: the endpoint may simply not be in this scan. 420 resources kept their URL and changed verdict, and 231 of those sit on a single host.
A seller showed us that our index kept an old verdict for URLs that had dropped out of our scan, with nothing saying how old it was. payability_verdict, find_endpoints and host_summary now return verdict_age_days with every endpoint verdict, and payability_verdict states the date an old negative verdict was observed.
Still zero across the scanned catalogue.
