## 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 resolve402-e-invoice-readiness-check-c85741da
```

Example prompt: Can you check if Renault (SIREN 775 700 342) can receive a Peppol electronic invoice today — I need to know which formats they support and whether the French e-invoicing mandate already applies to them?

## When to prefer this

Use this endpoint when you need to determine programmatically whether a specific European company is Peppol-capable before routing an electronic invoice, or when you need to understand which e-invoicing mandate and timeline applies to a company in France, Belgium, Netherlands, Germany, Italy, or other EU countries. Prefer this over generic company lookup endpoints when the specific question is e-invoice readiness and Peppol registration status.

## Known failure modes

- Company not found in any registry — no charge, returns not-found status
- Invalid SIREN/SIRET checksum — validation error returned
- VAT number format incorrect or country prefix missing
- Company found but not registered on Peppol — 200 with registered:false, still charged
- Peppol Directory temporarily unavailable — partial results or error
- Country not supported or outside EU/EEA scope

## How this service works

Check whether a European company can receive an electronic invoice today, through which Peppol participants and formats, and which national e-invoicing mandate applies to it from which date. Give a French SIREN or SIRET, an intra-EU VAT number, a national company number with its country (BE KBO, NL KvK, IT P.IVA, DE), or a company name and country. The Peppol Directory is queried by free text AND by exact participant on every scheme plausible for the country (FR 0002, 0009, 0225 SIREN_routing, 9957; BE 0208, 9925; NL 0106, 0190, 9944; DE 0204, 9930; IT 0211, 0210, 9906...), results are merged and unrelated hits dropped; document types are mapped to stable capabilities (Peppol BIS Billing invoice and credit note, CII, Factur-X, PINT, order) with a can_receive_einvoice verdict. Identity from Sirene/RNE (France) or VIES; obligation calendar per country with its official source. Charged only if the company is found (a company found but not on Peppol is a 200, registered:false). 20 free calls/day per IP with header X-Free-Trial: 1.

## Output

Returns a verdict on whether the company can receive e-invoices today (can_receive_einvoice boolean), the list of Peppol participant IDs and schemes they're registered under, the e-invoice document types and formats supported (BIS Billing, CII, Factur-X, PINT, order), company identity data from Sirene/RNE or VIES, and the applicable national e-invoicing mandate with its effective date and official source. A 200 response with registered:false is returned if the company is found but not on Peppol.
