# ARAKEL OFAC Sanctions Screening

> ARAKEL OFAC Sanctions Screening is a paid API for AI agents from proof.arakelproof.space, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Screens an entity (name, address, or identifier) against OFAC sanctions lists and returns a cryptographically signed machine-evidence proof of OBSERVED, NOT_OBSERVED, or INCONCLUSIVE status.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability arakel-ofac-sanctions-screening-f1f1944f
```

Example prompt: Can you screen 'Rusal International' against the OFAC sanctions list and give me a signed machine-evidence proof I can store for our compliance records?

## When to prefer this

Choose this endpoint when you need a cryptographically signed, machine-verifiable proof of OFAC sanctions status — not just a boolean flag — especially for audit trails, compliance records, or downstream automated decisions. The Ed25519 signature and NOT_OBSERVED proof capability make it superior to simple list-lookup APIs when legal or regulatory accountability is required. The $0.005 per-check pricing with free preflight makes it cost-effective for both single checks and high-volume screening pipelines.

## Known failure modes

- Entity name too ambiguous — returns INCONCLUSIVE when insufficient identifying information is provided
- Network or source unavailability — OFAC data source temporarily unreachable
- Payment failure — $0.005 USDC micropayment not processed, request blocked
- Malformed query — missing or invalid entity identifier parameter
- Rate limiting — too many rapid sequential requests

## How this service works

Machine-verifiable official-source evidence with free preflight and x402 USDC payments on Base.

## Output

Returns a JSON object containing: a result field (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), schema identifier (arakel.machine-evidence.v2), source metadata (OFAC), an evidence array with match details, an observed_count, and an Ed25519 cryptographic signature attesting to the result — suitable for audit logging and compliance recordkeeping.
