## 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 sirenic-belgian-company-registry-lookup-kbo-bce-d536c965
```

Example prompt: Can you pull up the official KBO/BCE registry details for Belgian company number 0403199702 — I need the legal name, status, registered address, VAT number, and NACEBEL activities?

## When to prefer this

Use this endpoint when you specifically need official Belgian company data from the KBO/BCE register, including legal form, NACEBEL sector codes, establishment units, VAT number, or LEI. Prefer this over generic EU company search when you already have the Belgian enterprise number and need authoritative, daily-refreshed government data for compliance, KYC, or supplier verification purposes.

## Known failure modes

- Invalid or malformed enterprise number (not 10 digits, contains dots/spaces) — returns 400 or validation error
- Enterprise number not found in KBO/BCE — returns 404
- KBO/BCE data source temporarily unavailable — returns 503
- Number format includes dots or spaces instead of plain digits — rejected by path parameter validation

## How this service works

Official Belgian company registry lookup (KBO/BCE, Banque-Carrefour des Entreprises / Kruispuntbank van Ondernemingen). Query: /v1/eu/entreprise/BE/0403199702 (10-digit enterprise number, with or without dots). Returns legal name, legal form, normalized status, incorporation date, registered office, NACEBEL activities with French labels, the establishment-unit list, VAT number and LEI, plus a link to the official register entry — Belgian company data from KBO/BCE open data, refreshed daily.
