## 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-sdn-wallet-screening-abc038ba
```

Example prompt: Before we send that USDC payment, screen the recipient wallet address 0x1234abcd5678efgh for OFAC sanctions — I need to know if it's a hit or clear, which sanctions programs it's tied to, and whether it needs manual review.

## When to prefer this

Use this endpoint when you need exact-match OFAC SDN screening for a specific cryptocurrency wallet address before executing an on-chain payment, onboarding a user, or for real-time treasury compliance checks. Prefer this over manual SDN lookups or batch compliance tools when you need fast, per-address, structured results with sanctions program metadata programmatically accessible to an AI agent or payment pipeline.

## Known failure modes

- Invalid or malformed wallet address returns an error or unexpected result
- OFAC SDN XML source temporarily unavailable may cause stale or failed lookups
- Address format mismatch (e.g. wrong chain encoding) may not match SDN entries correctly
- Payment failure (insufficient USDC balance) results in 402 response with no screening data
- Network timeout on downstream Treasury XML fetch

## How this service works

Exact-match OFAC SDN wallet screening for sanctioned digital currency addresses. Screens one wallet address against Treasury's public SDN advanced XML and returns hit or clear status, asset coverage, sanctioned entity metadata, sanctions programs, list source, listing date, and a manual-review signal for onchain payment and treasury controls

## Output

Returns a hit or clear status for the queried wallet address, along with asset coverage (which digital currencies are covered), sanctioned entity name and metadata, applicable sanctions programs (e.g. SDGT, CYBER2), the SDN list source, the listing date, and a boolean or signal indicating whether manual review is recommended.
