Verify a BlindOracle receipt against the parts a buyer cannot check alone: is the proof_id really in BlindOracle's append-only proof rail, does its payload still hash to the stored row, and does the row's HMAC-SHA256 verify against the signing key. Also recomputes content_sha256 and confirms the Base payment, so one call is a complete answer. Deterministic, no LLM. The self-checkable half is free forever in the published verify-blindoracle-receipt skill (RQ-BO-RECEIPT-VERIFY-01).

Payment shape (25 most recent sampled): 12 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 13 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified). Most of what arrives here is not x402-shaped; the figures above are gross USDC, not x402 revenue.

Peak day 2026-09-04: 48 payments. Last indexed day 2026-09-28: 2. 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 39 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
