Pre-payment clearance for agents. Call this BEFORE settling with a merchant over x402/AP2: give the merchant domain (optionally the amount and the price you expect to pay). Onyx assembles a single hard clearance — PROCEED / REVIEW / HOLD — from its Ed25519-signed observation log: Onyx-Verified status, live TLS/reachability/off-domain-redirect facts, domain age, and observed-vs-expected price. Facts with methods disclosed, signed and verifiable; Onyx never asserts the merchant is honest — it ensures you read real signed ground-truth before you move money. The check agents run at the payment chokepoint. (price: $0.05 USDC, tier: metered)
