## 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 sanctioned-wallet-check-a1968696
```

Example prompt: Before I send this payment, screen these wallet addresses for OFAC sanctions and tell me if any are blocked: 0x1234abcd..., bc1qxyz..., TRX9abc...

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call OFAC sanctions screen for crypto addresses across multiple chains (ETH, BTC, TRX, SOL, USDT, etc.) without maintaining your own SDN list integration. Ideal as a pre-payment AML gate in agent workflows processing crypto transactions, or for compliance checks during user onboarding on crypto platforms. Supports batch screening of up to 50 addresses per call, making it efficient for bulk use cases.

## Known failure modes

- Invalid or malformed address format causes rejection
- Exceeding 50 addresses per request returns an error
- Unsupported blockchain network address types may not be recognized
- Network timeout from the hosted render.com service under load
- OFAC SDN list may have a slight update lag vs. the official database

## How this service works

Check up to 50 crypto addresses (ETH, BTC, TRX, USDT, SOL and more) against the OFAC SDN list's digital currency addresses: PASS or BLOCK with the sanctioned party and program. Use as a pre-payment AML gate.

## Output

For each submitted address, the endpoint returns a PASS or BLOCK verdict. For blocked addresses, it includes the name of the sanctioned party and the specific OFAC program (e.g., UKRAINE-EO13685, CYBER2) associated with the address. Clean addresses receive a simple PASS.
