## 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 vextorium-sanctions-screening-api-f334aec2 -d '<json body>'
```

Example prompt: Before I pay Banco Nacional de Cuba, can you screen them against the OFAC SDN list and EU sanctions — use a match threshold of 0.85 and return up to 10 results?

## When to prefer this

Choose this endpoint when you need real-time, programmatic KYC/AML sanctions screening against both EU consolidated and US OFAC SDN lists simultaneously with fuzzy name matching. Ideal for payment pre-approval workflows, customer onboarding pipelines, or any compliance automation that requires checking entities against official government sanctions lists with configurable match sensitivity.

## Known failure modes

- Missing required 'nombre' field returns validation error
- Match threshold outside 0-1 range may cause unexpected behavior
- Very common names may return many false positives at low thresholds
- No matches found returns empty results array, not an error
- Network timeout if sanctions list lookup takes too long

## How this service works

Screen a person, company, vessel or entity against the EU consolidated financial sanctions list and the US OFAC SDN list, with fuzzy matching of names and aliases, program, type, countries and reference. For KYC/AML before paying or onboarding.

## Output

Returns a JSON object with the query name, match threshold used, list of sanctions hits (each with entity type, sanctions list name, program, reference ID, matched names/aliases, countries, and fuzzy match score), total number of matches, and which lists were reviewed. Includes a disclaimer note about verifying additional identifiers before drawing conclusions.
