How this service works

$0.001 OFAC destination-wallet preflight for autonomous agents, plus machine-verifiable official-source evidence over x402 USDC on Base.

Output

Returns a JSON object containing a risk_score (numeric), risk_level (e.g. 'low'), OFAC flags array, a payment decision ('VERIFIED' or otherwise), a verified boolean, and an Ed25519 signature binding the payment to the caller-supplied request/response hashes. Schema field is 'arakel.x402.payment-risk-check.v1'.

Example use cases

Preflight sanctions check for agent payment

“I'm about to have my agent send 100 USDC on Base to wallet 0x9F3...d21 — can you run an OFAC sanctions screen on that destination address first and tell me the risk level before we proceed?”

Verify completed USDC payment with signed receipt

“Can you verify that Base transaction 0x7a2...b9c sent exactly 25.50 USDC to 0x4E1...f08 with at least 2 confirmations, and give me a machine-signed receipt binding the payment to my request hash 0xabc...111 and response hash 0xdef...222?”

Compliance audit trail for autonomous agent workflow

“My agent just completed a USDC payment on Base with tx hash 0x3c8...e44 — verify it settled to the correct payee 0x6D2...a17 for 10 USDC and get me a cryptographically signed compliance attestation I can attach to the audit log.”

When to prefer

Choose this endpoint when an autonomous agent needs both a compliance sanctions screen (OFAC) AND cryptographic payment verification in a single call over the x402 micropayment protocol. Prefer it over generic blockchain explorers when you need a machine-signed, audit-ready receipt binding the payment to specific request/response hashes. Best suited for agent-to-agent payment workflows on Base where regulatory compliance evidence is required.

Side effects

Transaction hash not found or not yet confirmed on Base — returns unverified decision
Destination wallet matches OFAC sanctions list — returns high risk_level with flags populated
Insufficient confirmations — verification withheld until min_confirmations threshold met
Mismatched payee or amount — payment decision returned as unverified
Invalid or malformed wallet address input — request rejected
x402 payment not included or insufficient — endpoint returns 402 Payment Required
