Example prompt: Can you look up the Swiss company with UID CHE-105.805.977 in the Zefix registry and tell me its legal name, address, and current registration status?

## When to prefer this

Use this endpoint when you need to verify or enrich data about a Swiss-registered company, confirm a CHE UID is valid, or retrieve official registration details from the Swiss Federal Commercial Registry (Zefix). Prefer over generic web search when structured, authoritative Swiss corporate data is required.

## Known failure modes

- Invalid UID format returns an error (must follow CHE-XXX.XXX.XXX pattern)
- Company name too ambiguous returns multiple or no results
- Company not found in Zefix returns empty or 404 response
- Payment not included or invalid results in 402 Payment Required
- Rate limit exceeded returns 429
