AgentResolver Provider Launch Check — Reference Contract
GET-first $0.05 USDC x402 seller-launch verification reference contract. Verifies a known-good x402 provider route end to end and returns a machine-readable launch report; production sellers use the same endpoint with their own provider fields.

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 8 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
