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.

Is the demand real?

spread30.8/40

Organic Demand Score measures the shape of the money and not its size or its honesty: how many distinct wallets paid, how evenly the dollars fell across them, and how many came back. Revenue is excluded on purpose, because a big number is not evidence anyone wanted the product. These are also the exact quantities a wash trader would optimise, so it is a starting point and not a verdict.

What it sells

31 endpoints listed, priced $0.0100 to $0.0500, settling on BNB Chain, Base, Solana, eip155:143, eip155:196.

Daily USDC into this address across the tape, 2026-08-04 to 2026-10-02. It shrank over that window. A missing day is a day the sweep did not run, not a day with no revenue.

Registry claim against the chain

The directory credits this service with 3,400 calls over 30 days. The chain shows 216 settled payments in the last 24 hours alone. Registry counters are not demand and can be bought, so they are shown here for contrast rather than as a measurement.

First seen in the registry on 2026-08-04; paid at 0x93053f1e…a0f13f.

Grades here come from paying this service and recording what happened, or from calling it where it is free. Settlement figures are swept daily from Base USDC Transfer logs. Nothing on this page is sponsored.
