It is the right choice for any task that requires confirming a Swiss business identifier is real and correctly formatted without needing full company profile data.

## Known failure modes

- Malformed UID format not matching CHE-xxx.xxx.xxx pattern returns validation failure
- Non-existent UID number returns ok: false
- Network or upstream registry timeout returns an error response
- Missing or empty value field returns a schema validation error
