Answers HTTP 402

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

unknown

unknown. We hold no reading for this seller's endpoints.

x402-style payments, last 7 days (Base)

x402-style paymentsMethod: 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.

This window shows the pattern of machine noise (few payers, dust amounts), so it does not count toward the evidence ranking.

All USDC received at this payout address: $0.00 (includes payments that are not x402)

Reading: x402-style payments to this payout address on Base, exact read of the 7 days to 2026-11-02, every block of the window: 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; Sato Hub's own payer wallets are left out

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.

Claim this merchant

Sign a message from the payout address 0xdcbf15…352ec0 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.
