get_circular_signal — wash / circular-settlement signal
Is the volume real? Wash/circular-settlement signal per facilitator: flagged clusters, flagged volume and share, self-funding percentage, detection date. The check sellers can't self-report; methodology public. Attributed to the facilitator only — never a seller wallet or an operator name. Cluster figures are as of detection_date, which is not the same day as the snapshot they are served beside; both dates are on the response.

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 2026-08-17: 3 payments. Last indexed day 2026-09-01: 2. Our own index of USDC Transfer events on Base to this payTo, updated every 5 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 5 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
