Relationships

x402 payments on Base · 13 October 2026 – 20 October 2026 · 8 days

No x402 payment reached this seller’s wallet on Base in the window, so it has no buyers to read relationships from.

Relationships are patterns in the x402 payments we observe on Base over the window: a buyer is a wallet that paid this seller’s payTo wallet, and came back means it paid on two or more different days. A wallet is not an agent, and a relationship is a pattern of payments, not a claim about who anyone is or who runs a wallet. Bought alongside and the switches leave out wallets that paid more than 30 sellers in the window: a wallet that pays everyone says nothing about what goes together.

Going rate, the median of the 25 matched sellers with a listed price (of 25 matched): $0.01 a call. This seller’s endpoints run $0.001–$0.1, and the going rate falls inside that range — so no single over/under verdict is fair. Compare per endpoint.

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.
