How this service works
RWA risk gate: score a TOKENIZED ASSET (treasury, stock, credit) BEFORE an agent buys it. POST {target:{payto_address:<token contract>, network:eip155:1|eip155:8453}} returns 0-100 risk, allow/review/block, is_permissioned_security and signals: proxy-aware transfer-restriction scan (ERC-1404/3643/allowlist/pause) with a behavioral transfer simulation, live pause state, issuer identity and issuer OFAC screening. Not investment advice.
Output
Returns a 0-100 risk score and an allow/review/block decision based on the payee address's on-chain settlement history, including signals like address age, facilitator-aware payer diversity, and settlement maturity, along with a confidence value for the assessment.
Example use cases
Automated payment firewall for agent swarms
“Set up a payment guard that screens every x402 recipient my agents hit before sending USDC—block anything scoring above 60, auto-approve under 40, and queue the middle ones for me to review in batches.”
Compliance-first treasury for RWA transfers
“I'm building a tokenized real estate settlement layer on Base—before my agent transfers any RWA to a buyer wallet, check if that address passes OFAC and Travel-Rule screening, and reject anything that doesn't get an allow decision.”
Scam-endpoint detection for API marketplace
“My agent pulls API endpoints from a marketplace contract and pays them for data via x402—run 402Sentinel on each payee wallet before it sends payment so we don't accidentally fund a prompt-injection attack or honeypot.”
Technical details
Endpoint
POSThttps://402sentinel.com/api/assess/rwaWhen to prefer
Use this endpoint when an AI agent is about to make an x402 pay-per-call payment and needs pre-payment counterparty risk screening based purely on on-chain settlement behaviour. Prefer it over generic blockchain analytics when you specifically need an allow/review/block policy decision tailored to x402 micropayment flows on Base.
Side effects
- Target payto_address missing or malformed — returns 400 validation error
- Address has no on-chain history — low confidence score returned with review/block decision
- Unsupported network specified — returns error or falls back to default
- The x402 payment for the API call itself fails — endpoint inaccessible without valid payment
- Insufficient on-chain data for meaningful scoring — low confidence indicated in response
