How this service works
Machine-verifiable official-source evidence with free preflight and x402 USDC payments on Base.
Output
A JSON object conforming to arakel.machine-evidence.v2 schema containing: a result field ('OBSERVED', 'NOT_OBSERVED', or 'INCONCLUSIVE'), the OFAC source identifier, an evidence array with supporting detail, an Ed25519 cryptographic signature over the response, and an observed_count. The signed payload allows downstream verification of the evidence without re-querying.
Example use cases
Pre-transfer sanctions compliance check
“I'm about to send USDC to wallet 0xAbc123...def456 — can you run an OFAC sanctions screen on it and tell me if it's flagged, along with the cryptographic proof?”
Counterparty due diligence before onboarding
“We're onboarding a new partner who gave us their crypto wallet bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq — can you check it against OFAC and get me a signed NOT_OBSERVED certificate if it's clean?”
Automated compliance audit of received payment
“Someone just sent funds to our treasury from wallet 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf — pull the OFAC sanctions evidence for that address so I can log it for our compliance records.”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/ofac-wallet-screenWhen to prefer
Choose this endpoint when you need cryptographically signed, machine-verifiable OFAC sanctions evidence for a specific wallet address — not just a pass/fail flag. Particularly valuable when you need NOT_OBSERVED proofs for audit trails, when compliance records require a verifiable signature, or when building automated AML pipelines that must produce tamper-evident compliance artifacts. The $0.005 per-call pricing and free preflight make it cost-effective for high-volume screening.
Side effects
- Invalid or malformed wallet address returns an error before billing
- Address format not recognized for a given chain returns INCONCLUSIVE
- OFAC data source temporarily unavailable returns INCONCLUSIVE with source error
- Rate limit exceeded returns 429
- Payment not included or insufficient returns 402 with payment requirements
