# LimitGuard Entity Trust Check

> LimitGuard Entity Trust Check is a paid API for AI agents from api.limitguard.ai, paid per call via x402, $0.85/call, status unknown (last checked 2026-10-09).

Performs a full entity trust assessment across 8 verified data sources (KVK/CBE registry, sanctions, country risk, WHOIS, IBAN, VAT/VIES, wallet screening, x402 history) and returns a 0-100 trust score with cluster and recommendation.

## 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-3c082e09 -d '<json body>'
```

Example prompt: Can you run a full trust check on 'Acme Corp BV' in the Netherlands — I have their KVK number 12345678 and domain acmecorp.nl — and tell me their trust score and whether I should approve transacting with them?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-source trust assessment of a business entity before initiating a transaction, contract, or automated payment. Prefer this over the lightweight quick-check endpoint when you need full due diligence across all 8 data sources. Choose this when KYB depth, sanctions screening, VAT validation, and wallet risk all matter simultaneously.

## Known failure modes

- Missing required fields (entity_name or country) returns 400 validation error
- Unknown or unsupported country code returns error or degraded score with fewer sources checked
- Entity not found in any registry returns low trust score with risk flags
- Invalid IBAN or VAT number format causes validation source to fail gracefully
- Sanctions database timeout may reduce sources_checked count
- Wallet address on unsupported chain returns partial result

## How this service works

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

## Output

Returns a JSON object with: trust_score (0-100), cluster label (e.g. 'verified'), recommendation (e.g. 'APPROVE'), list of risk_factors, country, entity_name, and number of sources_checked (up to 8). Aggregates results from KVK/CBE registry, OpenSanctions, CPI/FATF country risk, WHOIS, IBAN validation, EU VAT/VIES, wallet screening, and x402 payment history.
