## 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 sanctions-check-ofac-sdn-list-screening-9d8c821e
```

Example prompt: Can you check if the wallet address bc1qv7k70u2zynvem59u88ctdlaw7hc735d8xep9rqq is on the OFAC sanctions list before I send funds to it?

## When to prefer this

Use this endpoint when you need a fast, pay-per-use OFAC SDN sanctions screen for any blockchain address (EVM, Bitcoin, Solana, Tron, etc.) without requiring sign-up or a subscription. It is ideal for agent workflows that need on-demand compliance checks before executing transactions, and supports multiple chain formats in a single API. Prefer this over subscription-based compliance services when volume is low or usage is sporadic.

## Known failure modes

- Invalid or malformed address format (fails regex pattern ^[A-Za-z0-9:]{20,120}$)
- Address parameter missing from query string
- Payment not completed (x402 payment required, 0.002 USDC)
- Sanctions list data temporarily unavailable or stale
- Network timeout fetching OFAC list from upstream source
- Address is valid but on an unsupported chain format

## How this service works

Is this wallet on the OFAC sanctions list? Screens an address (EVM, Bitcoin, Tron, Solana) against the Treasury SDN list (about 1,060 digital currency addresses) and reads live USDC and USDT freeze status on chain. Sanctions check for a wallet address on any chain: is it on the OFAC SDN list (read from Treasury's official SDN.XML, about 1,060 digital currency addresses: Bitcoin, Tron, Ethereum, USDT, Solana and more), under which entry and programs, with the list's publication date.

## Output

Returns a JSON object with: a boolean 'onSdnList' indicating whether the address is sanctioned, a 'summary' string describing the match status, a list of 'sdnMatches' with entity details (UID, name, type, currency, programs), the sanctions list metadata (name, source URL, fetchedAt, publishDate, number of addresses on list), 'frozenAnywhere' flag, 'stablecoinFreezes' info, and a legal disclaimer.
