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 with a result field of OBSERVED, NOT_OBSERVED, or INCONCLUSIVE indicating whether the queried wallet address appears in OFAC sanctions data, along with a structured evidence array from the official OFAC source, an Ed25519 cryptographic signature for machine-verifiability, and a count of observed matches. Schema version arakel.machine-evidence.v2.
Example use cases
Pre-transfer compliance check for DeFi app
“I'm about to send 500 USDC to wallet 0x1a2b3c4d5e6f... — can you screen it against OFAC sanctions data first so I know it's safe to proceed?”
Agent fleet payment gating
“Before any of our agents execute a payment to an external wallet, I want them to check that address against official U.S. Treasury OFAC data and block the transfer if it shows up as sanctioned.”
Historical sanctions status audit
“Can you check whether wallet 0xDeAdBeEf... appeared on the OFAC sanctions list at any point between January 1, 2024 and March 31, 2024?”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/agent/wallet-preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or application needs machine-verifiable, cryptographically signed evidence of OFAC sanctions status for a wallet address prior to executing a crypto transfer. The free preflight tier makes it ideal as a low-cost compliance gate before committing to a payment. Prefer this over generic blockchain analytics services when you need official U.S. Treasury OFAC sourcing and a signed evidence record for auditability.
Side effects
- Missing required 'q' query parameter returns validation error
- Invalid date-time format for 'from' or 'to' parameters causes schema rejection
- Wallet address not recognized or malformed may return INCONCLUSIVE
- Network or upstream OFAC data source unavailability may produce error or INCONCLUSIVE result
- Rate limiting or payment failure on paid endpoints blocks access
