How this service works
Use when an agent needs a normalized profile of a South Korean company for KYB, research or sales. Input: id (companyId from /v1/kr/company/resolve). Output: JSON profile: names, business/corporate/DART/stock ids, market, KSIC code, founding date, fiscal year end, address, homepage, KONEPS supplier registration. No CEO names. DART data is a weekly snapshot of KRX-listed companies (asOf in response). Data: OpenDART, KONEPS. Example: ?id=kr-dart-00126380
Output
Returns a JSON object containing the company's Korean and English names, address, region, homepage URL, founding date, fiscal year end month, DART corporate code, stock code, business registration number, corporate registration number, KSIC industry code, stock market listing (market and short name), procurement vendor details from KONEP (employee count, registration status, business lines), data source provenance, and attribution notes. CEO names, phone, and fax numbers are deliberately omitted.
Example use cases
Korean stock research pre-trade check
“I'm looking at investing in a Korean company with DART code kr-dart-00126380 — can you get me their full company profile including their KOSPI listing details, stock code, and fiscal year end?”
B2B supplier due diligence
“We're vetting a Korean supplier whose business registration number is 1248100998 — look them up as kr-brn-1248100998 and tell me their official company name in English, their address, and whether they're registered as a procurement vendor on KONEP.”
Regulatory filing cross-reference
“I need to cross-reference a Korean firm's identifiers — fetch the company profile for kr-dart-00126380 and give me their DART corporate code, corporate registration number, and industry KSIC code.”
Technical details
Endpoint
GEThttps://1gateway.dev/v1/kr/company?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, normalized Korean company profile data keyed by a DART code or business registration number — especially when you need both registry identifiers and stock market listing data in a single call. It is particularly useful for financial research, supplier due diligence, and regulatory cross-referencing of Korean firms. It requires no signup or API key and charges only on success.
Side effects
- Invalid or malformed company ID (must match ^kr-(dart-\d{8}|brn-\d{10})$) returns an error
- Company not found in DART or business registry returns empty or not-found response
- Upstream OpenDART or KONEP unavailability may cause transient errors (not charged on failure)
- Providing a non-Korean company ID format will be rejected by schema validation
