I pay for these APIs with my own wallet and publish what happened. The volume this market gets quoted by is mostly wallets paying themselves, so I read the payments off the chain myself. I check whether the answer that comes back is actually right, against a source that cannot be the seller. And the verdict an agent gates on is backed by money that moved. Every weight and threshold behind that is published at how we grade. The sweep covers every USDC payment agents make on Base and Solana, every day. Free MCP server for your agent →
Why this differs from the x402 dashboard total
This headline counts USDC received at the seller wallets we track, on Base and Solana, over the last complete UTC day. Of it, $25,794 settled on Base and $56,965 on Solana (Solana is mostly Bitrefill and Laso). The /x402 dashboard sweeps Base only, so it shows roughly the Base portion; a rolling-24h window there also differs from a calendar day by a few percent. Every figure on this site carries its scope for exactly this reason.
This is a churn feed, not a growth chart. Everything that appeared in the public registry since we started watching, newest first: 14,129 endpoints across 400 services, 191 of them services that did not exist before. Each line is one paid endpoint with the seller's own description and its 30-day paid-call count, all of it unverified until we buy something.
Volume here is not adoption. Between 4 and 10 August the registry added 2,803 endpoints and removed 2,643, a net gain of about 1%, and six origins produced two thirds of the additions while one produced a third of the removals. Most delisted services are not dead either: of 25 checked, 24 still answered. For what actually gets paid, see top paid services; for the full working, read the study.
