AgentResolver x402 Settlement Verify — Base USDC Receipt
$0.001 GET-first post-payment verification for autonomous agents. Given a Base transaction hash, independently checks the public Base receipt, exact USDC EIP-3009 payment shape, Transfer logs, confirmation depth, and optional expected recipient/amount assertions. Settlement evidence only; not provider identity or fulfillment verification.

On-chain payments
Peak day 2026-09-17: 3 payments. Last indexed day 2026-09-17: 3. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-09-16; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 5 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
