How this service works
Machine-verifiable official-source evidence with free preflight and x402 USDC payments on Base.
Output
A JSON object containing: a `result` field with value OBSERVED, NOT_OBSERVED, or INCONCLUSIVE; a `schema` identifier (arakel.machine-evidence.v2); a `source` object identifying the official data source checked (e.g. OFAC); and a `signature` object with an Ed25519 cryptographic signature attesting to the result's authenticity.
Example use cases
Sanctions check before crypto payment
“I'm about to wire USDC to a new vendor — can you run their company name 'Meridian Trading LLC' through OFAC and other official sources and get me a signed machine proof of the result?”
Onboarding compliance screen
“We're onboarding a new business partner called 'Novex Capital Group' — screen them against all available official watchlists and give me a full counterparty dossier with a cryptographic proof I can attach to the compliance file.”
Wallet address watchlist verification
“Check wallet address 0xDeadBeef99 against OFAC sanctions and any other enabled official sources — I need a signed OBSERVED or NOT_OBSERVED proof returned in machine-readable format.”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/machine/proveWhen to prefer
Choose this endpoint when you need machine-readable, cryptographically signed compliance evidence — particularly NOT_OBSERVED proofs — from official sources like OFAC, suitable for automated compliance workflows, audit trails, or counterparty due diligence before financial transactions. Prefer it over generic sanctions databases when you need an Ed25519-signed proof artifact rather than a human-readable report.
Side effects
- Entity not found in any enabled source → returns INCONCLUSIVE
- Invalid or malformed entity identifier → 400 bad request
- Source temporarily unavailable → may return INCONCLUSIVE or error
- Payment not received or insufficient → 402 Payment Required
- Rate limit exceeded → 429 Too Many Requests
