## 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-sanctions-batch-address-screener-83f8d821 -d '<json body>'
```

Example prompt: Can you check these crypto wallet addresses against the OFAC sanctions list to make sure none of them are blacklisted before we process payments: 0xABCD1234..., 0xEF567890..., and 0x99AABB11...?

## When to prefer this

Choose this endpoint when you need to screen multiple crypto wallet addresses (up to 100) against the OFAC SDN list in a single API call for compliance, AML, or pre-transaction vetting workflows. It's ideal for batch use cases like exchange onboarding, DeFi protocol risk checks, or payment processor compliance pipelines. Prefer it over single-address lookup when processing lists of wallets, and over building your own SDN parser when you need a maintained, daily-updated feed via a simple POST call.

## Known failure modes

- Empty or missing addresses array returns validation error
- More than 100 addresses in a single call exceeds the batch limit
- Malformed or non-string address entries may cause parsing errors
- Stale data risk: list is updated daily so very recent OFAC additions may not be reflected immediately
- Payment failure via x402 if USDC balance on Base is insufficient
- Rate limiting after 3 free daily calls without payment

## How this service works

Are any of these crypto addresses on OFAC’s SDN sanctions list? Up to 100 addresses screened in one call, checked by Distill against OFAC’s own SDN file. Updated daily. $0.05 per call (x402, USDC on Base); 3 free calls a day.

## Output

Returns a result for each submitted crypto address indicating whether it appears on OFAC's SDN sanctions list, based on a daily-updated copy of the official OFAC SDN file maintained by Distill. Up to 100 addresses are screened per call.
