## 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 factline-invoice-supplier-verification-b99ae4d7
```

Example prompt: Before we pay this invoice from Colruyt Group, can you run a full supplier check — their VAT number is BE0400378485, the IBAN on the invoice is BE68539007547034, the invoice came from finance@colruyt.be, and they're based in Belgium?

## When to prefer this

Choose this endpoint when an AI agent needs to vet a supplier or vendor invoice end-to-end before authorising payment — it uniquely combines sanctions/PEP screening of the full corporate hierarchy, IBAN validation with country consistency, VAT VIES verification, Polish whitelist checking, Dutch bankruptcy lookup, and email domain analysis in a single call, saving the need to orchestrate multiple specialist APIs. Prefer it over standalone IBAN or VAT validators when you want a holistic pre-payment risk signal for European suppliers.

## Known failure modes

- Invalid or unrecognized IBAN format — returns validation error
- VAT number not found in VIES (service may be temporarily unavailable)
- Company not found in any official register for the given country
- Insufficient identifying information provided (no name, VAT, IBAN or ID supplied)
- Sanctions database lookup timeout or third-party service unavailability
- Country code not supported or missing — reduces scope of checks performed

## How this service works

Supplier invoice check and vendor verification before payment: company, IBAN, VAT, sanctions. Use before an agent pays a supplier invoice: checks the supplier in official registers, screens it, its directors, owners and parent companies against EU, UN, UK and US sanctions and PEP, matches the VAT number, checks the IBAN (valid, same country as the company, registered on the Polish VAT whitelist), the sender's email domain and Dutch bankruptcy, and whether the supplier is on Peppol. One...

## Output

Returns a structured report covering: company identity confirmed in official registers, sanctions and PEP screening result for the company and its UBOs/directors/parent companies, VAT number validity and name match via VIES, IBAN validity and country consistency, Polish VAT whitelist status (if applicable), email domain vs supplier website domain comparison, Dutch bankruptcy check (if KvK provided), and Peppol network membership — all in one consolidated response.
