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 one of three verdicts (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), a schema identifier (arakel.quick-check.v1), a source object identifying which official source was queried (e.g. OFAC), and a cryptographic Ed25519 signature attesting the machine-generated evidence.
Example use cases
Onboarding vendor sanctions screening
“Before we onboard this new supplier, can you check whether 'Caspian Freight Group' appears on the OFAC sanctions list and get me a signed machine proof of the result?”
Wallet address compliance check
“I need a signed compliance check on wallet address 0xABCD1234 against OFAC — run it through ARAKEL and tell me if it's observed, not observed, or inconclusive.”
Automated NOT_OBSERVED proof for audit
“Generate a machine-signed NOT_OBSERVED proof for 'Novara Capital Ltd' from ARAKEL so I can attach it to our due-diligence file as evidence they're clear of sanctions.”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/machine/quick-checkWhen to prefer
Use this endpoint when you need a fast, cheap ($0.005), cryptographically signed machine-evidence verdict from official sources — especially when you need a legally defensible NOT_OBSERVED proof, when you are building automated AML/KYC pipelines that require auditable attestations, or when you want per-check pay-as-you-go compliance screening without subscribing to a full sanctions database. Prefer this over batch endpoints for single-subject real-time checks where latency matters.
Side effects
- Subject identifier not recognized or malformed — returns INCONCLUSIVE or error
- Payment of $0.005 USDC not received — request rejected before check is run
- Queried official source temporarily unavailable — INCONCLUSIVE result returned
- Rate limiting if too many quick checks are submitted in rapid succession
- Invalid source ID provided — source not found or not enabled error
