One seller wallet, each chain read on its own. We never send a payment, so we never observe what a paid call returns. Unknown means we hold no reading, not that anything failed.
Pricing
The price each endpoint registered in the x402 catalogue. A listed price is a registration, not an observed charge.
Claim this merchant
Sign a message from the payout address 0xabf4fa…e2a9d0 to claim this page or download its payment ledger. 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.
