## 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 sitecheck-crypto-address-ofac-sanctions-screener-7ee531cc
```

Example prompt: Can you check if these crypto addresses are on the OFAC sanctions list: 0x0330070FD38Ec3bB94F58FA55D40368271E9e54A and 0x1234567890abcdef1234567890abcdef12345678?

## When to prefer this

Use this endpoint when you need a fast, low-cost OFAC SDN sanctions check specifically for cryptocurrency wallet addresses (up to 20 at a time). Prefer this over manual OFAC lookups when building compliance workflows, KYC/AML pipelines, or pre-transaction screening into an AI agent. It covers multiple chains (ETH, ARB, BCH, BSC, and more). Note: a clean result is not a legal clearance — always confirm hits on the official OFAC portal.

## Known failure modes

- Missing 'addresses' query parameter returns an error
- More than 20 addresses submitted may be rejected or silently truncated
- An address not on the list does NOT confirm it is safe — only that it wasn't found on OFAC's SDN list
- Stale data risk if OFAC updates the list intra-day before the daily extract refreshes
- False negatives possible for newly sanctioned addresses not yet in the daily extract

## How this service works

Screens up to 20 crypto addresses (EVM chains, Bitcoin, Solana, Tron, Litecoin, Monero, XRP, Zcash and more; 18 currencies) against the US Treasury OFAC Specially Designated Nationals (SDN) digital currency address list. Reports sanction status, list name, SDN program, and source link. Never declares an address clean: reports 'not on the checked lists'. Information only, not financial advice.

## Output

Returns a JSON object with per-address results indicating whether each address is sanctioned, its status label, the list name it was found on (or null), and the currencies it is listed under. Also includes metadata: which sanction lists were checked, total screened count, total sanctioned count, the timestamp of the check, the data source attribution, and a disclaimer.
