Solana · payout u5zcwMcmrn7qAN4zUJzLhpLDQv81qtFDfZR1ohCrMs9
Answers HTTP 402
1 of 1 probed endpoints answered HTTP 402 with a parseable payment payload
checked 2026-09-28
Method: one unpaid request per listed endpoint. A 402 with a payment payload a client could parse counts. Nothing is paid.
x402-style payments, last 7 days (Base)
unknown. not measured on this chain yet
no reading date
Method: counted when the transaction carries a signed USDC authorization (EIP-3009), the settlement x402's exact scheme uses. Some non-x402 gasless sends use it too.
Delivery is not measured. We never send a payment, so we never observe what a paid call returns. Unknown means we hold no reading, not that anything failed.

Claim this merchant
Sign a message from the payout address u5zcwMcm…hCrMs9 to claim this page. Claiming proves control of the payout key. It says nothing about the service behind the address, and it does not change how this merchant is ranked. No email, no account: the signature is the whole credential, and signing a message costs no gas and moves nothing.
