## 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 eu-e-invoice-routing-check-vies-peppol-mandate-57fd8d97
```

Example prompt: Can I e-invoice the company with VAT number DE123456789 — are they on Peppol, is their VAT active in VIES, and what format should I use?

## When to prefer this

Use this endpoint when you need a single-call answer to 'can and should I e-invoice this company?' before generating or sending an invoice. It combines VIES VAT validation, Peppol Directory lookup, country mandate rules, and format recommendation in one call — avoiding the need to query multiple APIs separately. Prefer it over raw VIES or Peppol lookups alone when you need actionable routing guidance, not just validation.

## Known failure modes

- Invalid or malformed VAT number / Peppol ID returns an error or empty result
- VIES service temporarily unavailable causing lookup failure
- Company not found in Peppol Directory (no Peppol endpoint registered)
- Country mandate data may lag behind recent regulatory changes
- Non-EU VAT numbers not supported

## How this service works

Can I e-invoice this company? EU VAT (VIES) + Peppol Directory registration + country B2B e-invoice mandate + recommended format

## Output

Returns a structured response indicating: whether the EU VAT number is valid in VIES, whether the company is registered in the Peppol Directory, the country-level B2B e-invoice mandate status, and the recommended e-invoice format (e.g. Peppol BIS 3, FatturaPA, XRechnung) for that counterparty.
