• assess_counterparty

  Assess the risk of an x402 counterparty (a payTo address) BEFORE paying. Returns a 0-100 risk_score, an allow/review/block decision, honest confidence/coverage, and a ready-to-apply recommended_policy (per-counterparty caps + approval/denylist), scored from on-chain settlement behaviour on Base + a delivery-outcome flywheel. Call before authorizing any x402 payment above your risk threshold. Costs $0.002 (paid automatically in USDC).

• assess_counterparty_deep

  Like assess_counterparty but scans more on-chain settlement history for a higher-confidence read. Use for larger or higher-stakes payments. Costs $0.02 (paid automatically in USDC).

• assess_rwa

  RWA risk gate — score a TOKENIZED ASSET (tokenized treasury/stock/credit) BEFORE buying it. Detects PERMISSIONED securities an agent can buy but NOT transfer/redeem (= trapped funds): proxy-aware transfer-restriction scan (resolves the EIP-1967 implementation; ERC-1404/ERC-3643/allowlist/freeze/pause), a behavioral transfer simulation (on-chain revert = the gate is live), live pause state, token identity (symbol/name/supply), and issuer/admin identity + issuer OFAC screening. Returns risk_score 0-100 + allow/review/block + is_permissioned_security + honest not_checked gaps (backing/peg/holder …

• compliance_check

  Pre-pay COMPLIANCE screen for regulated-money x402 flows. Returns compliance_decision (pass/flag/block), diligence_tier, obligations, and checks: OFAC sanctions (hit = hard block), counterparty due-diligence tier from the on-chain risk engine, structuring/smurfing detection (many sub-threshold payments to one counterparty aggregating to a reportable sum in 24h — pass target.agent_id, e.g. your wallet, to enable it), and the FATF Travel-Rule threshold reported as informational. Screening support for compliance workflows — not legal advice. Costs $0.02 (paid automatically in USDC).

• firewall

  Buyer-side payment firewall: should YOUR agent make THIS payment now? Where assess_counterparty vets the seller, this vets the payment instruction in the context of your agent's own history + provenance. Returns allow/hold/block + signals: routing_anomaly (payTo swapped vs the address you usually pay = fraudulent routing), velocity_anomaly (drain), amount_anomaly (overcharge), provenance_flag, counterparty_risk, injection_destination (if the payTo appears in the untrusted page/tool-output you're acting on, the destination was injected — pass it as context.untrusted_text), intent_mismatch (pass…

• firewall_outcome

  FREE. After a firewall verdict, report what actually happened so 402Sentinel learns which signals are predictive and downweights noisy ones (hard-block safety signals stay deterministic). Pass the assessment_id (fw_…) from a prior firewall call.

• firewall_record

  FREE. Seed your agent's payment history so the firewall has a behavioural baseline (record past/known-good payments). agent_id and the wallet-ownership signature are attached automatically from your configured wallet, so the seeded history is trusted.

• recommend_policy

  Turn a counterparty's risk into an enforceable spending policy you can apply to your agent wallet. Returns an allow/limit/deny decision plus recommended_policy: max_payment_usdc (per-counterparty cap), daily_cap_usdc, add_to_denylist, require_human_approval. Costs $0.002 (paid automatically in USDC).

• report_outcome

  FREE. After you pay a counterparty, report whether they delivered so 402Sentinel's settlement-reliability flywheel can learn. Pass the assessment_id returned by a prior assessment.

• verify_service

  402Sentinel Verified (opt-in badge): submit YOUR OWN service's payTo for a deep settlement-graph audit (facilitator-aware, multi-hop, exchange-labelled). If it passes (organic, sufficient confidence), a signed time-boxed (30d) credential is issued and your service joins the public allow-list at /api/verified. Positive-only: failing audits are returned privately, never published. SLOW (deep on-chain scan, up to ~3 minutes). Costs $0.02 (paid automatically in USDC).
