## 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-nts-business-registration-status-lookup-sample-f7f17be9
```

Example prompt: Can you check the business registration status for a Korean company using the National Tax Service sample lookup — I want to see what fields come back like business status code, tax type, and whether they can issue invoices?

## When to prefer this

Use this endpoint when you need to verify the registration status or tax type of a Korean business entity via the National Tax Service (국세청), particularly for vendor onboarding, KYB compliance, invoice verification, or pre-payment due diligence. This is a sample endpoint, so prefer it for testing integration logic or validating response schema before using a production equivalent.

## Known failure modes

- No matching business found — returns empty data array with match_cnt of 0
- Invalid or malformed business registration number — may return no results
- Sample endpoint may return static/mock data rather than live NTS data
- API unavailable or payment not processed — 402 or 5xx error
