## 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`):

Example prompt: Before we wire payment to this Korean supplier, can you verify their business registration number 123-45-67890 matches CEO Kim Cheol-su with an opening date of 2015-03-22 using live NTS data?

## When to prefer this

Choose this endpoint when you need to verify Korean businesses specifically against live government (NTS) source data rather than commercial databases. Ideal for KYB compliance, vendor onboarding, or pre-payment due diligence involving Korean counterparties where you need to confirm the business number matches both the CEO name and founding date.

## Known failure modes

- Invalid or malformed 10-digit business registration number returns validation error
- Business number not found in NTS records returns no-match or not-found result
- Representative name mismatch returns failed verification
- Opening date mismatch returns failed verification
- NTS data source temporarily unavailable returns service error
- Payment not provided returns 402 Payment Required

## Output
