How the paid API works

How to read these numbers

Source: the public x402 discovery registry, photographed once a day. A seller missing from that registry is missing here; that is not the same as not selling.
“Payers” are endpoint counts summed: a wallet paying two endpoints counts twice. A wallet is not an agent.
“Money” is paid calls times list price. It is an estimate, not settled revenue, and it misleads for sellers whose price varies per call.
Where a seller lists several prices, the page shows the range. A single over/under verdict against the going rate is given only when it holds for every endpoint the seller lists.
Movement is the change in a rolling 30-day total between stored days, not a daily count.
Self-dealing is not filtered. A seller can pay its own endpoint, and those calls count here like any others. A high rank is a count of paid calls, not a judgement that a service is good, safe or real.
“Who actually paid” is read straight off Base: x402 payments are the transfers a facilitator settled on a buyer’s signature, in the last day only. A wallet is not a person, and one operator can hold many. “One payer” means every x402 payment came from one wallet; “concentrated” means ten or more payments with the busiest three wallets sending 80% or more. Both are facts about the payers, not verdicts on the seller. Hosts paid into one wallet are grouped: usually one operator, sometimes a platform collecting for several.
