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

2324 x402-style payments from 88 distinct payers, $45.65 USDC in the last 7 days (Base, exact read)

Payments

Outside payers
88
USDC
45.65

All USDC received at this payout address: $45.66 (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.
