  description: Machine evidence with free preflight, $0.005 quick checks, NOT_OBSERVED proofs, batch checks, and counterparty dossiers across enabled official sources.
  x-guidance: For crypto wallet sanctions screening, first use the free /v1/machine/lookup-quote endpoint with type=ofac-wallet and q set to the destination wallet address; if payment_recommended is true, call /v1/ofac-wallet-screen for $0.005. For simple OFAC, FDA, USAspending federal-award, or Federal Register lookups, first use the free /v1/machine/lookup-quote endpoint with type and q. If payment_recommended is true, call the returned lookup_path; these buyer-intent lookups normally cost $0.005 via x402. Use /v1/machine/quote for advanced source-specific checks, signed proofs, NOT_OBSERVED proofs, change detection, or bundles. Never pay when a free preflight returns payment_recommended=false or predicts INCONCLUSIVE.
