What Agents Buy.

Independent reviews of the x402 APIs behind agentic commerce. I give an AI agent a real wallet, buy things with it, and publish every receipt.

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.

Grades

No purchase-based grade yet. Everything below was measured, by paying this seller or by sweeping the chain, and none of it is editorial.

Accuracy against a primary source

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.

Did it deliver what it promised?

4 of 4 endpoints we paid returned everything their own published schema promised.

This is a paid delivery check: we called the endpoint with its own advertised input and compared the response against its own advertised output. It is the one thing free probing cannot see.

Verifiable receipts

6 paid calls 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.
