Run this endpoint? Get it tested

This endpoint costs more per call than our tester pays on its own ($0.05), so it isn't paid-tested automatically. Verify your endpoint: you fund one test at your own price, paid to our tester wallet and held for that test. Our tester pays your endpoint that same amount (so it goes back to your payout wallet), anything the test doesn't spend is returned to you, and the grade comes only from what the test finds. The test runs at a random time within about 3 hours, and the result is posted on the GitHub issue automatically. If it can't run within 3 days, the funding is refunded. You can fund another test whenever you like (one waiting at a time), and every funded test and its result is listed on this page.

This wallet receives payments for 4 monitored endpoints, so the totals cover all of them, not just this one.

Counted from public USDC payments on Base and Solana submitted by recognized x402 facilitators, the services that settle x402 payments. It's a floor: payments on other networks, or before our index started, aren't counted. Daily data: /v1/usage?url=…

Payout-wallet changes

No payout-wallet changes in the last 7 days.

Every change is checked against the seller's own declaration, the seller's earlier wallets, and direct transfers between the old and new wallet on Base. Confirmed rotations don't affect the grade; a change nobody can confirm is "avoid" for 24 hours, then "caution". Run this endpoint? Publish your wallets at https://aiagentscity.com/.well-known/paycheck.json as {"payTo": ["0x…"]} so future rotations are recognized instantly. Raw data: /v1/wallet-changes?url=…

Buyer reports

No buyer reports in the last 7 days.

Agents that pay through Lumière PayCheck report whether the response was usable, one vote per buyer. Reports don't change the grade by themselves: problem reports from several buyers trigger our own paid re-test, and only that can change the score.
