## 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-counterparty-government-check-7a36baea
```

Example prompt: Can you screen 'Meridian Global Logistics' against government watchlists and get me a signed machine-evidence proof of whether they appear in any official sources like OFAC?

## When to prefer this

Choose this endpoint when you need a cryptographically signed, machine-verifiable proof of a sanctions or government watchlist check — particularly when OBSERVED/NOT_OBSERVED evidence needs to be stored for compliance, audit trails, or regulatory reporting. Prefer it over informal lookups when the result must be non-repudiable and carry a digital signature. Best suited for counterparty onboarding, AML/KYC workflows, and vendor due diligence where structured evidence is required.

## Known failure modes

- Missing required 'q' query parameter returns an error
- Invalid date-time format for 'from' or 'to' parameters causes a parsing error
- Entity name too ambiguous to match any source may return INCONCLUSIVE
- Source unavailability may result in partial source coverage or INCONCLUSIVE result
- Payment failure or insufficient USDC balance blocks the check

## 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 (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), a schema identifier (arakel.counterparty-government-check.v1), a per-source breakdown (e.g. OFAC result), and an Ed25519 digital signature attesting to the authenticity of the check.
