## 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 maritime-sanctions-vessel-search-bb826d96 -d '<json body>'
```

Example prompt: Can you run a sanctions screen on the vessel 'PETROV STAR' — try a fuzzy name match and also check IMO number 9876543 — and filter results to Russian-flagged ships?

## When to prefer this

Use this endpoint when you need maritime-specific sanctions screening with fuzzy vessel name matching, call sign lookup, or IMO number verification — especially when flag-state filtering is needed. Prefer this over generic OFAC name-batch screening (the sibling endpoint) when the entity is clearly a vessel rather than a person or company.

## Known failure modes

- No matching vessels found returns count:0 with empty vessels array
- Invalid or unrecognized IMO number format may return empty results or an error
- Overly common vessel name with fuzzy matching may return large noisy result set
- Stale source publish date if sanctions list has not been recently updated
- Missing required input fields returns a validation error

## Output

A list of matching sanctioned vessels with match scores, vessel names, associated sanctions programs, IMO numbers, detailed descriptions, and the publish date of the underlying sanctions source data.
