## 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 nexari-german-company-search-323335a5
```

Example prompt: Can you search for the German company 'Siemens AG' and tell me their Handelsregister number and which court they're registered at?

## When to prefer this

Use this endpoint when you need to quickly identify German companies by name and retrieve their commercial register number and court, especially for KYB (Know Your Business) workflows, due diligence, or business partner verification. Prefer this over the live register endpoint when real-time freshness is not required and cost efficiency matters. Prefer over general web search when structured, machine-readable register data is needed.

## Known failure modes

- Company name not found in register — returns empty results or 404
- Missing or invalid accept_terms_hash causes request rejection
- Ambiguous company name returns multiple matches requiring further filtering
- Data may be outdated as this is not a live registry pull
- Missing required query parameter 'q' causes validation error

## How this service works

Firmenauskunft DE: Unternehmen nach Namen suchen, liefert Firmen-ID, Registernummer, Gericht. German Company Lookup: search German companies by name. Quelle: Registerdaten via OpenRegister, kein amtlicher Auszug. Source: German register data via OpenRegister, not an official extract.

## Output

Returns structured data including the company's internal ID, Handelsregisternummer (commercial register number), and the name of the registering court (Registergericht) for matching German companies. This is sourced from OpenRegister and is not an official certified extract (kein amtlicher Auszug).
