Run this endpoint? Get it tested

This endpoint is within our automatic test budget ($0.05 per call), but our automatic paid tests are paused for now, so it's waiting for its next one. Don't want to wait? Verify your endpoint: you fund one test at your own price, our tester pays your endpoint that same amount (so it goes back to your payout wallet), anything unspent is refunded, and the grade comes only from what the test finds. Or request a free re-test; it runs when automatic tests resume.

This wallet receives payments for 1196 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://api.fadeandco.workers.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.
