Run this endpoint? Get it tested

This endpoint answers our paid call with a sign-in requirement (no money taken), so it stays C with a "needs its own sign-in" note until a test gets in. That isn't counted as a failure.

  1. Let our tester in: give it a test account (a short private form; results are labeled "tested with a seller-provided account"), or set up a wallet sign-in (it signs in with its own wallet, like any agent).
  2. Then check your setup: we re-read your paycheck.json and queue a paid re-test.

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.

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

Buyers reviewed 2026-10-24: 86% of the volume comes from independent buyers. We group buyer wallets by the wallets that funded them; payments from groups of 3+ wallets funded by one source, or by the seller itself, aren't counted as independent. We count customers, not wallets.

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://agents.chain.link/.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.
