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.

This wallet receives payments for 34 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://1gateway.dev/.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.
