## 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-entity-trust-check-faf4dab6 -d '<json body>'
```

Example prompt: Before we pay this invoice, can you run a full trust check on 'Acme Corp BV' based in the Netherlands — their KVK number is 12345678, VAT number NL123456789B01, and domain is acmecorp.nl — and tell me whether we should approve the transaction?

## When to prefer this

Use this endpoint when you need the most comprehensive single-call trust assessment of a business entity, combining registry verification, sanctions screening, financial validation, domain analysis, and wallet screening in one response. Prefer it over the quick risk score endpoint when you need a defensible, multi-source compliance decision — especially before executing a payment, onboarding a new vendor, or entering a business relationship. Ideal when you have partial or full identifying information (KVK, CBE, VAT, IBAN, or wallet) to maximize source coverage.

## Known failure modes

- Entity name or country not provided — returns 400 validation error
- KVK or CBE number format invalid — returns 400 with field-level error
- IBAN checksum fails validation — returns 400 with IBAN error
- Entity not found in any registry — returns low trust score with empty risk_factors
- External data source (e.g. OpenSanctions, VIES) temporarily unavailable — reduced sources_checked count with partial score
- Wallet address malformed or unsupported chain — returns 400 or ignores wallet check
- Rate limit or payment failure — returns 402 or 429

## How this service works

Full entity trust check across multiple verification layers: KVK/CBE registry, OpenSanctions, country risk (CPI/FATF), domain WHOIS, IBAN validation, EU VAT/VIES, wallet screening, and x402 payment history. Returns trust score 0-100 with cluster and recommendation.

## Output

Returns a JSON object with a numeric trust score (0-100), a cluster label (e.g. 'verified'), a recommendation string (APPROVE/REVIEW/REJECT), an array of risk factors, the number of sources checked, and the entity's country code.
