Answers HTTP 402
2 of 2 probed endpoints answered HTTP 402 with a parseable payment payload
checked 2026-10-03
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)
unknown. not measured
window ended 2026-10-05
All USDC received at this payout address: $0.17 (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.
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.
