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

x402-style payments, last 7 days (Base)

1outside payer

53 x402-style payments from 1 distinct payer, $0.34 USDC in the last 7 days (Base, exact read)

window ended 2026-10-28

Payments: 53
Payers: 1
USDC: 0.34

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: $0.34 (includes payments that are not x402)

Reading: x402-style payments to this payout address on Base, exact read of the 7 days to 2026-10-28, 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

By chain

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.

It says nothing about the service behind the address, and it does not change how this merchant is ranked.
