## 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-fuzzy-sanctions-screener-7f415c1e -d '<json body>'
```

Example prompt: Screen these names against the OFAC SDN sanctions list and tell me if any come back as matches: 'Viktor Bout', 'Reza Zarrab', 'Glencore Ltd'.

## When to prefer this

Choose this endpoint when you need fast, fuzzy sanctions screening specifically against the US OFAC SDN list — especially for batch checks of up to 50 names at once. It is ideal for KYC/AML workflows, counterparty due diligence, and automated compliance pipelines where the OFAC SDN list is the required data source. If you need screening against other sanctions lists (EU, UN, UK OFSI), this endpoint is not appropriate.

## Known failure modes

- Batch exceeds 50 names — request rejected
- Name input is empty or malformed — validation error
- Daily SDN refresh temporarily unavailable — stale or error response
- Very short or ambiguous name fragments may produce low-quality fuzzy matches
- Non-English character sets may reduce matching accuracy

## How this service works

Fuzzy sanctions screening against the US OFAC SDN list (public-domain source, refreshed daily): name in, scored matches with programs and aliases out. Batches up to 50. Coverage is OFAC SDN only — stated in every response.

## Output

Returns scored match results for each input name, including the matched SDN name, similarity score, associated sanctions programs, and any known aliases. Coverage is explicitly scoped to OFAC SDN only, as stated in every response.
