## 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 chainanalyzer-ofac-fatf-jfsa-sanctions-screening-for-blockchain-4248e18d
```

Example prompt: Can you check if the Ethereum address 0x1234...abcd is on any sanctions list — OFAC, FATF, or JFSA — and tell me which programs it's flagged under and when it was designated?

## When to prefer this

Use this endpoint when you need structured, multi-jurisdiction sanctions screening (OFAC, FATF, JFSA) for a specific blockchain address with machine-readable output including program codes and designation dates. Prefer this over generic AML risk scoring when you specifically need sanctions list compliance data for regulatory or KYC/KYB workflows.

## Known failure modes

- Invalid or malformed blockchain address format returns an error
- Address not found on any supported chain may return empty results rather than an error
- Rate limiting or payment failure (x402) blocks the request
- Unsupported blockchain network returns an error or empty result
- Sanctions list data may have a freshness lag if not updated in real time

## How this service works

OFAC / FATF / JFSA sanctions screening for any blockchain address. Returns hit list with sanction list source, designation date, and program code.

## Output

Returns a hit list of sanctions matches for the queried blockchain address, including the sanction list source (OFAC, FATF, or JFSA), the designation date, and the program code for each hit. Returns an empty list if no sanctions matches are found.
