## 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-entity-resolver-kr-entity-resolve-65c8282d -d '<json body>'
```

Example prompt: Can you resolve 'Samsung Electronics' to its official Korean company identifiers — I need the LEI, business registration number, DART corp code, and stock code?

## When to prefer this

Choose this endpoint when you need to resolve a Korean company name or partial identifier (stock code, bizr_no, etc.) to a complete, authoritative set of Korean corporate identifiers including LEI, DART corp_code, business registration number, and stock code. Prefer this over general company search APIs when the target entity is Korean and you need cross-registry ID reconciliation without requiring an account or API key — paying per call in USDC via x402.

## Known failure modes

- Low-confidence match when company name is ambiguous or abbreviated — returns multiple candidates with lower scores
- No match found if the entity does not appear in Korean registries or is too obscure
- Input array exceeds maxItems:100 limit — request rejected
- Malformed input items — returns validation error
- Slight name spelling errors may reduce match confidence or return wrong entity

## How this service works

Pay-per-call Korean company due diligence, company ID crosswalk, sanctions screening with Korean name variants, Upbit/Bithumb risk events, HWP to Markdown, business status, business-day calendar, address normalisation, law, rates, filings and more. No account or API key: pay each call in USDC on Base via x402.

## Output

Returns an array of matched entity results, each containing a cross-walked set of Korean company identifiers (LEI, bizr_no, jurir_no, corp_code, stock_code), canonical English company name, and a confidence score indicating match quality.
