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 OBSERVED, NOT_OBSERVED, or INCONCLUSIVE; the schema identifier (arakel.machine-evidence.v2); the source that was queried (e.g. id: 'ofac'); and a cryptographic signature block using Ed25519 algorithm — providing a tamper-evident, machine-readable compliance proof.
Example use cases
Pre-payment sanctions clearance check
“Before I wire funds to 'Meridian Exports LLC', get me a signed ARAKEL proof that they're not observed on the OFAC list — I need the machine-evidence result and signature for our compliance records.”
Automated onboarding KYC attestation
“We're onboarding a new vendor called 'BrightPath Solutions' — can you run them through ARAKEL and get a NOT_OBSERVED proof from OFAC so we have a signed attestation ready for our audit trail?”
Counterparty dossier for due diligence
“Pull an ARAKEL machine evidence check on 'Vladislav Torenko' against official watchlist sources and give me the signed result showing whether they're observed, not observed, or inconclusive.”
Technical details
Endpoint
GEThttps://proof.arakelproof.space/v1/machine/prove-not-observedWhen to prefer
Choose this endpoint when you need a cryptographically signed, machine-readable proof that a specific entity is NOT on a sanctioned or watched list — particularly for automated compliance workflows, audit trails, or agent-to-agent due diligence where human-readable reports are insufficient. Prefer it over manual screening tools when you need Ed25519-attested evidence compatible with automated verification pipelines and when OFAC or similar official-source coverage is required.
Side effects
- Entity identifier not found or ambiguous — may return INCONCLUSIVE
- Source list unavailable or temporarily offline — endpoint may return error or INCONCLUSIVE
- Invalid or missing entity parameter — HTTP 400 bad request
- Payment not settled — HTTP 402 payment required (x402 protocol)
- Rate limiting or quota exceeded — HTTP 429
- Signature verification failure on response — indicates data integrity issue
