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
A JSON object containing: a result field with one of OBSERVED, NOT_OBSERVED, or INCONCLUSIVE; a schema version identifier (arakel.machine-evidence.v2); source metadata (OFAC); an array of evidence objects; an Ed25519 digital signature for machine verification; and an observed_count integer indicating how many matches were found.
Example use cases
Pre-payment sanctions check for DeFi app
“I'm about to send crypto to 0xabc123...def789 — can you run an OFAC preflight screen on that wallet address so I have evidence it's clean before I execute the transfer?”
Compliance audit for received funds
“We just received a payment from wallet 0x9f8e7d...6c5b4a and I need to verify it's not on the OFAC sanctions list with a signed, machine-verifiable evidence record for our compliance files.”
Automated KYC gating for crypto onboarding
“A new user wants to connect their wallet 0x3344aabb...ccdd to our platform — screen it against OFAC sanctions right now and give me a signed result I can store for regulatory audit purposes.”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/ofac-wallet-preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need machine-verifiable, cryptographically signed evidence of OFAC sanctions status for a specific crypto wallet address — especially in automated compliance workflows where human-readable reports are insufficient and auditable, tamper-evident records are required. Prefer this over manual OFAC list lookups when you need a programmatic, repeatable pre-transfer check at $0.005 per call scale, and when your workflow requires Ed25519-signed evidence bundles for regulatory audit trails.
Side effects
- Missing required 'q' query parameter returns a 400 error
- Invalid wallet address format may return INCONCLUSIVE result
- Payment not completed via x402 USDC returns 402 Payment Required
- OFAC source temporarily unavailable may return INCONCLUSIVE
- Date range parameters in wrong format return validation error
- Rate limiting may occur on repeated rapid calls
