get_circular_signal — wash / circular-settlement signal
Agent payments have no chargeback. Paddock is pre-payment verification for AI agents. Screens an x402 service for circular, self-paid settlement volume, dated to the run that produced it.
Endpoint
https://paddock.finance/api/paddock/mcp/circular-signal?window=30d
Verification
Sustained protocol conformance over many checks from our infrastructure. Says nothing about content accuracy.
On-chain payments
Payment shape (8 most recent sampled): 8 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-09-29: 9 payments. Last indexed day 2026-10-08: 7. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 6 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
last 30 probes, oldest → newest · 100% pass · re-probed on its probe tier's interval (next_check_by on the record) from nohumans infrastructure — never self-reported
Payment protocols
x402 · MPP: This endpoint's 402 also offers payment over MPP (the "Payment" HTTP authentication scheme): stripe, tempo, as the endpoint names them. Read from our unpaid probes; mpp_offers lists each offer. Our paid verification and on-chain figures cover x402 on Base only.
Paid verification
Not yet paid-verified. Probe-based status above is liveness only.
