For the seller: make it payable from browser agents
- The 402 response has no Access-Control-Allow-Origin header, so a browser can't read the price quote. Fix: send Access-Control-Allow-Origin: * on 402 responses.
- The quote is in the PAYMENT-REQUIRED header, but it isn't listed in Access-Control-Expose-Headers, so browser code can't see it. Fix: Access-Control-Expose-Headers: PAYMENT-REQUIRED, PAYMENT-RESPONSE.
- The CORS preflight (OPTIONS) has no Access-Control-Allow-Origin, so a browser can't send the paid retry. Fix: Access-Control-Allow-Origin: * on OPTIONS too.
- The CORS preflight doesn't allow the PAYMENT-SIGNATURE header, so a browser can't send the payment. Fix: Access-Control-Allow-Headers: PAYMENT-SIGNATURE, Content-Type.

Recent paid tests
No paid tests in our recent history. Delivery isn't confirmed yet, so the grade is C at best.
Each paid test sends your listing's own example input (or your declared test request). Fixed something? Use the Get it tested box above.
Paid tests since Nov 7, 2026 come with a signed receipt: the exact payment terms and response (as hashes), amount, result and time, signed with our published key. How to check a receipt · All receipts for this endpoint (JSON)

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://scorestatus.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.
