53,495 paid endpoints are listed. 29,803 answered a real 402 at the last check.

Every x402 endpoint on the Coinbase Bazaar and x402scan, probed unpaid every six hours. A listing tells you the price a seller wrote down. This tells you whether the endpoint is reachable, whether it charges what it declared, and how fast it answers. Ranked by an assay score out of 100.

This is what makes stored state usable as agent MEMORY rather than as a write-once archive: each run overwrites the slot the last run parked, under a name you already wrote down.
