## 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 defi-shield-hazel-vercel-app-d4234db7 -d '<json body>'
```

Example prompt: Can you run an OFAC sanctions check on the name 'Viktor Petrov' and tell me if there's a fuzzy match on the SDN list?

## When to prefer this

Use this endpoint when you need to screen a person, organization, or entity name against the US OFAC SDN sanctions list with fuzzy matching tolerance — especially useful for DeFi/Web3 compliance workflows where exact name spelling cannot be guaranteed. Prefer this over exact-match solutions when dealing with transliterated or potentially misspelled names.

## Known failure modes

- Name too short or ambiguous — low-confidence fuzzy match returned
- SDN list data may not be fully up to date — stale match results
- Common names may produce high false-positive rates
- Missing or malformed name input returns validation error
- Service unavailable or payment failure returns error response

## Output

Returns whether the provided name matches any entry on the OFAC SDN list, along with a fuzzy match score and the closest matching SDN entry details, enabling compliance decisions.
