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.

Recent failed checks

The free checks we run every 30 minutes: uptime and a valid payment quote. Paid tests are in the section above.

1 check didn't pass in the last 7 days, and none of them count against this endpoint. It was on our side (our monitor being rate-limited, blocked, or having a problem), not the endpoint.

Time (UTC)What happenedWhat it meansAffects score?
2026-11-03 20:56:33 Monitor problem Our monitor had a network problem during this check. Not the endpoint's fault. No
What each result means
Blocked
The endpoint's protection (such as Cloudflare) rate-limited or challenged our monitor. That's about our monitor, not the endpoint, so it never affects the score.
Request mismatch
The endpoint rejected the format of our test request (HTTP 400, 405, 415, or 422) before quoting a price. That's about our request, so it never affects the score.
Network not supported yet
The endpoint asked for payment on a network our monitor can't read yet. That's our limitation, so it never affects the score.
Monitor problem
Our own network had an issue during that check. Never affects the score.
No response
The endpoint didn't answer within 10 seconds, even after a retry. Counts as downtime.
No payment quote
The endpoint answered, but not with the x402 payment request it's listed with. Counts as downtime.
Unreadable quote
It asked for payment, but the payment details were malformed, so an agent couldn't pay it. Counts as downtime.

Think this grade is wrong? Dispute it on GitHub. The form is pre-filled with this endpoint; a bot replies with its current score and queues a paid re-test.

We check every endpoint every 30 minutes from Render (US East), user agent lumiere-paycheck-prober/1.0 (+https://lumierepaycheck.org). Operators can allowlist it. Raw data: /v1/failures

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://xhagents.xyz/.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.
