Reported financials
Eleven verified DART values: revenue, operating income, pretax income, net income, assets, liabilities, equity, cash, and operating, investing, and financing cash flows.
Standard API brings DART financials, company records, and filing source links into one English JSON API for 313 Korean companies.
Public subscriptions are coming soon. We are preparing checkout and account activation. Explore the API now and leave your email to hear when it launches. No launch date has been announced.
Eleven verified DART values: revenue, operating income, pretax income, net income, assets, liabilities, equity, cash, and operating, investing, and financing cash flows.
Operating margin, net margin, liabilities/equity, quick ratio, and annual total-equity ROE. Each includes its formula and source inputs; missing inputs remain null.
DART statement lines and filing records, with fiscal period, statement scope, receipt number, source account, units, and collection timestamps where applicable.
Find the 313 covered companies, then check each company's reporting periods, data availability, and source timestamps before retrieving its financials.
Top 200 KOSPI and top 100 KOSDAQ companies by market capitalization, plus AI Value Chain companies. Up to eight retained fiscal reporting slots per company; not a long-term archive.
Unavailable financial values remain explicit nulls with missing-reason fields, so a missing disclosure is not mistaken for a reported zero.

Already have pilot access? Open Plan & billing for your access status, invoice enquiries, and cancellation contact. Existing signed order form and manual invoice arrangements are unchanged.
Data refreshes after DART filings are collected and processed. There is no guaranteed publication-to-API latency, quote feed, or real-time market-data service.
Keys on the same access plan share its allowance. Excess requests return HTTP 429; there is no automatic overage billing. The limits in API response headers are authoritative.
An authenticated request counts once its allowance is reserved, even if later processing returns an error. Authentication rejections and already exhausted limits do not consume another slot. See the documentation for details.
Responses use no-store headers. If paid-plan metering cannot be verified, requests return HTTP 503 rather than bypassing usage controls. Follow the documented retry guidance when the service is unavailable.
Seven company endpoint families plus company discovery, all in the same plan.
