## 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 korea-business-verify-kbv-company-name-search-149aa8e3
```

Example prompt: I need to find the Korean business registration number for a company called 'Samsung C&T' — search the Korean business registry by name and give me the top candidates with their confidence scores.

## When to prefer this

Use this endpoint when you know a Korean company's name (in English or Korean) but do not yet have its business registration number, which is required by sibling endpoints for status checks and KYB verification. Prefer this as the first step in any Korean company due diligence workflow.

## Known failure modes

- No matching company found for the given name — returns empty candidates list
- Ambiguous name matching multiple companies — returns multiple low-confidence candidates requiring manual selection
- Non-Korean company name with no registry match — returns empty results
- Misspelled or transliterated name not recognized — returns no results or low-confidence matches
- Service unavailability or payment failure — returns HTTP error

## How this service works

Search for a Korean company by name and get its business registration number. Use this when you only know what a company is called — in English or Korean — and need the 10-digit number that other lookups require. Returns ranked candidates with a confidence score and the evidence that tells similarly named companies apart: registration status, tax type and region.

## Output

Returns a ranked list of matching Korean companies, each with the 10-digit business registration number, a confidence score indicating match quality, registration status (active/suspended/closed), tax type, and region — providing the evidence needed to distinguish similarly named companies.
