Answers HTTP 402
2 of 3 probed endpoints answered HTTP 402 with a parseable payment payload
checked 2026-09-30
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)
199 x402-style payments from 5 distinct payers, $24.75 USDC in the last 7 days (Base, exact read)
window ended 2026-10-05
- Payments
- 199
- Outside payers
- 5
- USDC
- 24.75
All USDC received at this payout address: $24.75 (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.
