Use OpenDART from your AI
Search corporate disclosures filed with Korea's DART system via the official OpenDART API: resolve a company name or stock code to its corp_code, list annual/quarterly and major-issues filings, pull company profiles and key financials (revenue, operating profit, net income). The Korean counterpart of EDINET and SEC EDGAR. Requires a free OpenDART API key.
This server connects your AI client to OpenDART, the Financial Supervisory Service's official API over DART - Korea's electronic disclosure system where listed companies file their reports. For anyone tracking Korean competitors (semiconductors, batteries, autos, chemicals), this is the primary source.
Key features:
- resolve_company: turn a company name (Korean or English) or 6-digit stock code into the 8-digit corp_code that the other tools take. The corp-code master is a 100k-company archive, cached server-side so lookups stay fast.
- list_disclosures: filings by company, date range and type - periodic reports (annual 사업보고서, quarterly 분기보고서), major issues reports, ownership disclosures - each with a direct DART viewer link.
- get_company: profile with official names, market (KOSPI/KOSDAQ/KONEX), CEO, registration numbers, industry and fiscal year end.
- get_financials: key accounts (revenue, operating profit, net income, total assets/liabilities/equity) from a chosen year and period, consolidated by default, with two prior periods for comparison.
Report names and account names come back in Korean; the tool notes explain the common ones (매출액 = revenue, 영업이익 = operating profit).
Using the API requires a free 40-character key issued at opendart.fss.or.kr (English portal: engopendart.fss.or.kr) - email verification only, roughly 20,000 requests/day. Set it as DART_API_KEY in your Arlet environment variables.
