## 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 maxwell-x402-swiss-commercial-register-lookup-9c3bdb6b
```

Example prompt: Can you look up the Swiss company with UID CHE-105.909.036 in the Zefix commercial register and tell me its registered name, legal form, current status, and the municipality of its registered office?

## When to prefer this

Choose this endpoint when you need authoritative, official company-level facts for Swiss legal entities registered in the Zefix commercial register — particularly when verifying company status, legal form, or registered office for due diligence, KYC, or contract validation. Prefer this over general web search when you need machine-readable, structured data directly from Switzerland's official linked-data government source. Note: does not cover sole proprietorships or individual persons.

## Known failure modes

- Company UID not found in register: returns 404, no charge
- Invalid UID format: malformed CHE number may result in error or no match
- Name search ambiguity: common names may return multiple or no results
- LINDAS/Zefix upstream unavailability: service may be temporarily unreachable
- Sole proprietorships and natural persons are explicitly excluded and will not be found

## How this service works

Swiss companies from the commercial register (Zefix via LINDAS), by UID or name: registered name, legal form (eCH-0097 code), status, municipality of the registered office, purpose and the official register link. Company-level facts only; no persons or sole proprietorships. Uncached: 404, not charged.

## Output

A JSON object containing: the company's UID in both dotted and hyphenated format, registered name, legal form as an eCH-0097 code, current status, municipality of registered office, company purpose, a link to the official Zefix register entry, country code (ch), source attribution (Zefix via LINDAS), and licence information. Returns a 404 (not charged) if the company is not found.
