# ARAKEL Sanctions Watch – OFAC Monitoring Endpoint

> ARAKEL Sanctions Watch – OFAC Monitoring Endpoint is a paid API for AI agents from proof.arakelproof.space, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-10).

Monitors and screens entities against U.S. Treasury OFAC sanctions lists, returning machine-verifiable signed evidence of whether a person, company, vessel, or wallet was observed in new sanctions listings within a given time window.

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-sanctions-watch-ofac-monitoring-endpoint-132ecfb7
```

Example prompt: Screen 'Novaya Shipping LLC' for any newly observed OFAC sanctions listings over the past 24 hours and give me a signed, machine-verifiable result I can use for compliance records.

## When to prefer this

Choose this endpoint when you need cryptographically signed, machine-verifiable sanctions evidence sourced directly from U.S. Treasury OFAC — especially for autonomous agents performing compliance workflows, recurring monitoring, or audit-trail generation. Prefer this over generic sanctions databases when cryptographic proof of the result is required (e.g. for automated deal approval pipelines or regulatory filings). The x402 micropayment model ($0.005/call) makes it cost-effective for high-frequency monitoring without subscription overhead.

## Known failure modes

- Missing required 'q' query parameter returns a 400 or validation error
- Invalid date-time format for 'from' or 'to' returns a schema validation error
- Payment not provided or insufficient USDC results in 402 Payment Required response
- Ambiguous entity name with no matching records returns INCONCLUSIVE result
- Rate limiting or network issues may produce transient 5xx errors
- Very recent sanctions additions may not yet be indexed, producing false NOT_OBSERVED results

## 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 top-level 'result' field (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), an array of evidence records sourced from OFAC, a schema identifier ('arakel.machine-evidence.v2'), the source ID ('ofac'), an observed count, and an Ed25519 cryptographic signature enabling machine verification of the evidence's authenticity and origin.
