Answers HTTP 402

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)
231 x402-style payments from 9 distinct payers, $3.39 USDC in the last 7 days (Base, exact read)
window ended 2026-10-05
- Payments
- 231
- Outside payers
- 9
- USDC
- 3.39
All USDC received at this payout address: $3.39 (includes payments that are not x402)
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.
Reading: x402-style payments to this payout address on Base, exact read of the 7 days to 2026-10-05, 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
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 0x2c871c…27735f 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.
