This endpoint is within our automatic test budget ($0.05 per call), so we pay-test it ourselves at no cost to you. Fixed something, or think the grade is wrong? Request a free re-test: a bot replies on GitHub with the current score and queues a paid re-test.

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://utilsforagents.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.
