Form 10-K API – Structured SEC Form 10-K Data

Q: How do I get a company’s latest 10-K?

Call `/v1/filings?formTypes=10-K&ticker=AAPL&limit=1`, or use the financials endpoints to fetch standardized statements directly from the most recent annual filing.

What is Form 10-K?

Form 10-K is the comprehensive annual report U.S. public companies file with the SEC. It contains audited financial statements, a description of the business, risk factors, and management’s discussion and analysis (MD&A) of results.

It is the single most important disclosure for fundamental analysis: revenue, net income, the balance sheet, cash flows, segment detail, and forward-looking risk language all live here, tagged in XBRL.

With the Finsider Form 10-K API you skip EDGAR scraping and XBRL parsing entirely — request a company’s 10-K and get structured, standardized financials back in milliseconds.
