How this service works
Machine-verifiable official-source evidence with free preflight and x402 USDC payments on Base.
Output
Returns a JSON object containing: a result field (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), schema identifier (arakel.machine-evidence.v2), source metadata (OFAC), an evidence array with match details, an observed_count, and an Ed25519 cryptographic signature attesting to the result — suitable for audit logging and compliance recordkeeping.
Example use cases
Pre-payment counterparty sanctions check
“Before we wire $50,000 to Novex Trading LLC, can you check if they're on the OFAC sanctions list and get me a signed proof of the result?”
Crypto wallet OFAC screening
“Screen this wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE against OFAC sanctions and return a cryptographic NOT_OBSERVED proof if it's clean.”
Onboarding compliance verification
“We're onboarding a new vendor called 'Mahan Air' — can you run an OFAC sanctions check and give me the machine-evidence result with signature so we have an audit trail?”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/ofac-sanctions-screeningWhen to prefer
Choose this endpoint when you need a cryptographically signed, machine-verifiable proof of OFAC sanctions status — not just a boolean flag — especially for audit trails, compliance records, or downstream automated decisions. The Ed25519 signature and NOT_OBSERVED proof capability make it superior to simple list-lookup APIs when legal or regulatory accountability is required. The $0.005 per-check pricing with free preflight makes it cost-effective for both single checks and high-volume screening pipelines.
Side effects
- Entity name too ambiguous — returns INCONCLUSIVE when insufficient identifying information is provided
- Network or source unavailability — OFAC data source temporarily unreachable
- Payment failure — $0.005 USDC micropayment not processed, request blocked
- Malformed query — missing or invalid entity identifier parameter
- Rate limiting — too many rapid sequential requests
