Method: one unpaid request per listed endpoint. A 402 with a payment payload a client could parse counts. Nothing is paid.

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 3gM4YDDP…N4ZRaM 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.

The payment ledger is not available on Solana yet.
