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-machine-evidence-network-ofac-compliance-monitor-6d586711
```

Example prompt: Before we send payment to Acme Trading LLC, can you do a sanctions check to see if they appear on any OFAC lists right now?

## When to prefer this

Choose this endpoint when an AI agent needs machine-verifiable, cryptographically signed OFAC sanctions evidence — particularly for autonomous payment workflows requiring compliance preflight checks. It is ideal when you need both a real-time screening result and an auditable signed artifact. Prefer it over generic web search or unverified lookups when you need recurring monitoring with cadence guidance and a structured, agent-consumable response.

## Known failure modes

- Missing or empty 'q' query parameter returns a 400 or validation error
- Ambiguous name with insufficient detail may return INCONCLUSIVE
- Payment not settled via x402 USDC on Base results in 402 Payment Required
- Unavailable OFAC data source may cause INCONCLUSIVE result
- Invalid date-time format for 'from' or 'to' parameters causes schema validation failure

## 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 result field of OBSERVED, NOT_OBSERVED, or INCONCLUSIVE, a list of sources checked (e.g. 'ofac'), a recommended monitoring cadence (e.g. every 6 hours with next_check_after_seconds), a list of changed sources since last check, and an Ed25519 cryptographic signature over the evidence for machine-verifiable auditability. Schema version is arakel.agent-compliance-monitor.v1.
