## 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 korean-company-name-to-registration-number-lookup-b3029f3f
```

Example prompt: What's the corporate registration number (crno) and business registration number for 삼성전자 (Samsung Electronics)? I need to look up their official Korean company IDs.

## When to prefer this

Use this endpoint when you have a Korean company name and need its official corporate registration number (crno) or business registration number to pass to downstream Korean business data APIs. It is specifically designed for Korean companies and handles legal suffix variants automatically, making it preferable to manual registry searches or generic business lookup tools.

## Known failure modes

- Company name not found in registry — returns empty or error result
- Ambiguous company name matching multiple entities — may return wrong or multiple results
- Non-Korean company names will not resolve
- Network or upstream registry unavailability may cause timeouts
- Unusual or very new company names may not yet be indexed

## Output

Returns the corporate registration number (crno) and business registration number for the matched Korean company, handling legal suffix variants such as (주) automatically. These identifiers can then be used as inputs to other Korean business data endpoints.
