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.

Measured 2026-08-17 by paying this seller and comparing the number it returned with a source it cannot resell. A dated sample, not a live guarantee. Full corpus at /categories.

Verifiable receipts

1 paid call to this host are recorded as tamper-evident receipts, all delivered or graded accurate. Each can be re-verified independently, from the archived bytes up.

Evidence and how to verify it yourself

Graded against a source that cannot be a reseller: Coinbase/Kraken median. Returned 64262.0 versus a truth of 64269.8475.

Three independent checks, none needing trust in this site: integrity recomputes the id as a hash of the evidence, so any edit shows; verdict re-derives the result offline; raw re-reads the untouched bytes archived at pay time and reproduces the shape.
