## 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 limitguard-kyb-sanctions-screening-api-6ad1e60c -d '<json body>'
```

Example prompt: Can you run a KYB and sanctions check on Acme Corp BV in the Netherlands — their KVK number is 12345678 and their website is acme.example.com? I need to know if they're on any sanctions list, whether there's PEP exposure, and what their overall trust score is.

## When to prefer this

Choose this endpoint when you need comprehensive, multi-source KYB and sanctions screening for European businesses (especially Dutch KVK or Belgian CBE registered entities), EU VAT validation, or PEP exposure checks — particularly in agentic workflows requiring pay-per-call pricing via x402 or API key, with cryptographic audit trails. Prefer this over generic company data APIs when compliance-grade sanctions screening against OpenSanctions lists and trust scoring are required in the same call.

## Known failure modes

- Missing required input fields returns validation error
- Unknown or unregistered KVK/CBE number returns not-found result
- VIES VAT lookup may fail if EU VAT registry is temporarily unavailable
- Ambiguous entity name without country code may return low-confidence results
- Insufficient prepaid balance triggers payment required response
- Cached check_id lookup returns stale data if entity status has changed

## How this service works

Per-entity report built from one real check's signals: identity, sanctions and PEP screening, domain signals, trust score (risk.trust_score, 0-100, 100 = best), correlations with the caller's earlier reports, sources and an evidence hash. A source that did not answer is shown unavailable, never clean.

## Output

Returns a structured report including: entity details (name, country), sanctions screening result (match/no_match with threshold), PEP exposure status, domain age and status, risk cluster label (e.g. 'verified'), numeric trust score (0-100), trust level (high/medium/low), recommendation (APPROVE/REVIEW/REJECT), list of sources checked, a unique check_id and report_id, and a cryptographic report hash for auditability.
