## How to call it through Zero

```sh
zero fetch --capability johto-sanctions-screen-api-0c92e3f8
```

Example prompt: Can you run a sanctions screen on 'Bank Rossiya' as an entity against OFAC and UK lists, with a match threshold of 0.85 and return the top 5 results?

## When to prefer this

Use this endpoint when you need a fast, low-cost automated sanctions pre-screen against OFAC SDN and UK Sanctions List with fuzzy matching and a configurable confidence threshold. It is pay-per-call in USDC with no charge on failed or empty fetches, making it cost-efficient for high-volume compliance pipelines. Prefer it over manual lookups or heavier KYB workflows when you just need a quick watchlist verdict during customer onboarding, transaction monitoring, or counterparty checks.

## Known failure modes

- No name provided — returns 400 validation error
- Threshold outside 0.70–1.00 range — rejected by schema
- Limit value outside 1–20 — rejected by schema
- Country code not valid ISO-2 — rejected
- Upstream sanctions list fetch failure — call not charged
- Name too short (under 2 chars) or too long (over 200 chars) — rejected
- No matches found — returns empty matches array with NO_MATCH verdict and rows:0, not charged

## How this service works
