Pre-signature x402 payment-risk oracle. AI agents call forecast_payment before paying a counterparty and get a GO / HOLD / STOP verdict from settlement reputation, price-anomaly (quoted vs the payee's own median), and OFAC sanctions screening — plus a third-party-verifiable Ed25519 signed receipt. Verdict only; never takes custody. Free under $10 at risk; returns an x402 payment challenge over that.
Pay less for x402 APIs: free pre-payment checks, cheapest working service finder, web/PDF reader.
Indicative pricing, coverage and stack design for high-risk and crypto payment infrastructure.
