How this service works
Use when an agent must identify a South Korean company before looking up its profile or public-procurement record. Input: one of business_number (10 digits), dart_corp_code, stock_code (KRX, e.g. 005930) or q (company name, exact match ignoring 주식회사/(주)/spacing); first wins. Output: JSON companies with stable companyId, Korean and English names, stock code, DART code, match type, ambiguous flag. Data: OpenDART, KONEPS. Example: ?stock_code=005930
Output
A JSON object containing: the original query parameters echoed back, a count of matched companies, an ambiguous boolean flag, and an array of company records each with a stable companyId (e.g. kr-dart-00126380), Korean name, English name, KRX stock code, DART corp code, business registration number, match type (e.g. stock_code, name, business_number), and confidence score. Also includes data sources with retrieval timestamps and attribution strings from OpenDART.
Example use cases
KRX ticker to DART company profile
“I have the KRX stock code 005930 for Samsung Electronics — can you look it up and give me the DART corp code and stable company ID so I can pull its disclosure filings?”
Business number to company identity
“I've got a Korean business registration number 124-81-00998 from a vendor invoice — can you resolve that to the official company name and DART code so I can verify who it is?”
Korean company name disambiguation
“Look up the Korean company called '삼성전자' by name and tell me if the match is ambiguous or exact, and return its English name and stock code.”

Endpoint
GEThttps://1gateway.dev/v1/kr/company/resolve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify or canonicalize a South Korean company before performing downstream lookups (DART filings, KONEPS procurement records, financial data). It is the right choice when you have any one of: a KRX stock code, a DART corp code, a Korean business registration number, or a company name, and need to resolve it to a stable cross-registry identifier. Prefer this over general web search when you need a structured, machine-readable result with high confidence from authoritative Korean regulatory sources.
Side effects
- No company found for the given input — returns empty companies array with count 0

- Invalid business registration number format — 400 bad request
- Invalid stock code format (not 6 alphanumeric chars) — 400 validation error
- Company exists in KRX but not registered in DART — partial data returned
- Payment not made or x402 auth failure — 402 Payment Required
