Korea DART Shareholders covers who owns a Korean-listed company. Two endpoints serve it. The ownership endpoint returns insider and 5%-holder filings as they are made. The shareholders endpoint returns the register printed in the company’s DART periodic report. Coverage runs from 2022 onward, and every row links back to the original DART document.

​
What You Can Use Korea Shareholders For

Follow insider buying and selling at a Korean company filing by filing. Track a 5% holder’s stake as it builds or unwinds. Read the controlling shareholder and its related parties from the annual register. See how much of the company minority shareholders hold.

​
Two Endpoints, Two Grains

/kr/ownership is event-based. Each row is one filing, dated by report_dt, and you filter it with date_gte and date_lte. It has no year or report_period. /kr/shareholders is per periodic report. Each row belongs to one report for one business year, and you filter it with year. It does not accept date_gte or date_lte; passing them returns 400.

​
Ownership Kinds

kind separates the two filing types behind /kr/ownership. They follow different reporting rules and carry different fields. major_5pct is a 5%-holder report. It carries reporter, report_type, report_reason, the block in shares and ownership_pct, the change in shares_change and ownership_pct_change, and any shares under contract in contract_shares and contract_ownership_pct. insider is an executive or major-shareholder ownership report. It carries reporter, executive_position, is_registered_executive, is_major_shareholder, the holding in owned_shares and owned_pct, and the change in owned_shares_change and owned_pct_change. Fields that belong to the other kind are null.

​
Shareholder Register Kinds

kind separates the three tables behind /kr/shareholders. major is the largest shareholder and its related parties. Each row names the shareholder_name, its relationship to the largest shareholder and the stock_class, with holdings at the start and end of the period in beginning_shares, beginning_pct, ending_shares and ending_pct. minority is the minority-shareholder summary: shareholder_count against total_shareholder_count, and held_shares against total_shares, each with its percentage. major_change lists changes of the largest shareholder, with change_date and change_cause. A row of - values means the filer reported no change.

​
Filter to One Kind Before Summing

Rows of different kinds are not comparable and must not be summed together.Some rows are also the filer’s own subtotal lines, with shareholder_name of 계 or 합계. Samsung Electronics’ 2025 major table, in the example below, carries one 계 row per share class. Drop those before adding up a table, or the total is counted twice.

​
Key Korea Shareholder Fields

Share counts are counts, not money. Percentages are on a 0-to-100 scale. Numbers arrive as strings, exactly as filed. Text fields such as shareholder_name, relationship, stock_class and executive_position are the filing’s own Korean and are not translated. stock_class is 보통주 for common shares and 우선주 for preferred shares. Every row carries rcept_no, the DART receipt number, and filing_url, the original DART document. Cite that when quoting a number.

​
Korea Shareholders Date Convention

Ownership rows are dated by report_dt, the date the filing was made. date_gte and date_lte bound it. Register rows carry bsns_year, report_period and settlement_date, the balance date the register describes. report_period is annual, half, q1 or q3. There is no report_period filter, so read it on each row. Rows are returned newest filing first.

​
Korea Shareholders Coverage

Coverage is 2022 onward and is still backfilling, newest year and largest cap first. A missing older year for a small company means not yet loaded, not not filed.

​
Page Through One Kind at a Time

Pass next_cursor back as cursor to get the next page. Rows of different kinds can share a position inside one filing, so a page boundary can drop rows when you page through several kinds together. Filter to one kind, or ask for a limit large enough to take a year’s register in one page.
