The Problem

Every year thousands of companies expanding into Korea hit the same wall: Korean business data is locked behind a language barrier.

Government registries: Korean only
No English-language API for company verification
Manual research: 30+ minutes per company at $25+/lookup
Existing tools: Korean UI only

The Solution

One API call → verified Korean business data in clean English JSON.

curl -X POST 'https://api.apify.com/v2/acts/lazymac~korean-business-data/run-sync-get-dataset-items?token=$APIFY_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{"brn": "124-86-62507"}'

{
  "valid": true,
  "formatted": "124-86-62507",
  "regionCode": "124",
  "region": "Seongdong (Seoul)",
  "entityType": "Corporation (법인)",
  "taxOffice": "Seongdong Tax Office",
  "checksumOK": true
}

Pricing

Pay-per-event (effective 2026-05-11):

$0.10 per actor run start
$0.05 per validated record

Cheaper than 1 minute of analyst time. Zero language friction.

Use Cases

M&A research — verify any Korean target company in seconds
Korean market entry — supplier/distributor due diligence
K-content sourcing — K-pop production company verification
Cross-border KYC — Korean entity validation in your onboarding
Equity research — KOSDAQ/KOSPI ticker lookup with English metadata

Why now?

The global English market for Korean business data has zero direct competitors on Apify Store, RapidAPI, or any major API marketplace. Korea is the world's 13th largest economy with ~9 million registered businesses — and yet there's been no English programmatic interface.

This actor solves that.
