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, $36,727 settled on Base and $96,320 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 ranks money, not quality. Services are ordered by USDC actually received, so appearing at the top says a service is busy, not that it is good. Grades come from buying, and a dash simply means we have not bought from that one yet.

Demand is the shape of the money, not its size. broad means 20 or more buyers with no single one above 35% of the dollars. one wallet means a single wallet holds 90% or more. thin means five buyers or fewer. Hover a label for the top buyer’s exact share. This is a flag, not an accusation: one large genuine customer looks identical to a wallet paying itself, and this measurement cannot tell them apart. These are counts of wallets, not of people or companies: one wallet may be one customer, a fleet, or a seller paying itself.

Organic Demand Score is that shape as one number from 0 to 100, built from three things and nothing else: breadth, how many distinct wallets paid, up to 40 points on a log scale that tops out at 100 wallets; spread, how evenly the dollars fell across them, up to 40 points from the Herfindahl index; and repeat, what share of buyers came back, up to 20 points, topping out at 30%. Hover any score to see the three parts and how much data stands behind it. Revenue is deliberately excluded, because a large number is not evidence that anyone wanted the product. So is outflow, because money leaving a wallet is as often cost of goods or a treasury sweep as it is recycling, and nothing on chain tells them apart. A high score is not a clean bill of health. These are the exact quantities a wash trader would optimise, so read it next to Demand, never on its own: a perfect score built on a single wallet is a loop, not a market.

Revenue is USDC that actually landed on Base and Solana at the address each service asks buyers to pay, swept daily. Tape covers 50 days between 2026-08-04 and 2026-09-22. Every grade shown anywhere on this site was earned by paying the service and recording what happened; nothing here is scored by an automated probe.
