## 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 ofac-wallet-sanctions-screening-6a300e57
```

Example prompt: Before I send payment, can you screen the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 against OFAC and other sanctions lists — check it on both Ethereum and Base chains and give me a signed compliance receipt?

## When to prefer this

Use this endpoint when an AI agent needs a real-time, official sanctions compliance check on a crypto wallet before executing a payment, onboarding a counterparty, or logging a compliance decision. Preferred over manual checks because it returns a cryptographically signed machine-readable receipt suitable for audit trails, covers multi-chain mixer exposure, and checks official OFAC SDN crypto addresses rather than names only. Choose this over generic wallet analytics tools when you need a structured PASS/FAIL verdict with a verifiable compliance signature.

## Known failure modes

- Missing required 'wallet' query parameter returns validation error
- Unsupported wallet format returns error
- Network timeout from on-chain data providers may delay response
- Payment not made or x402 payment rejected results in 402 response
- Invalid chain name in 'chains' parameter may be ignored or cause partial results
- Cached result returned if recently screened (cached:true flag)

## How this service works

Crypto wallet sanctions & compliance screening (AML/KYT): screen any EVM/Solana/Bitcoin/Tron/XRP wallet against the official OFAC SDN crypto list (UN/UK declared) with mixer (Tornado Cash) exposure and wallet age, returning PASS/WARN/BLOCK and a cryptographically SIGNED compliance receipt (list-version-pinned, verifiable offline) for audit. OFAC wallet check, travel-rule / KYT counterparty screening with an auditable attestation an agent can keep.

## Output

Returns a JSON object containing: verdict (PASS/FAIL/REVIEW), confidence score (0–1), which sanctions lists were checked (OFAC SDN crypto addresses, UN Security Council, UK OFSI/FCDO), any matched lists, reasons with codes and weights, mixer/tornado cash exposure hits on specified chains, wallet first-seen age, data freshness metadata including OFAC list fingerprint, and an ed25519-signed compliance receipt with verifiable claims.
