About StockFit API

StockFit API is a revolutionary solution designed to provide developers, quants, and research platforms with unparalleled access to SEC filing data. Unlike conventional financial APIs that often force users to choose between low-cost options with accuracy issues or expensive enterprise contracts that can cripple a startup's budget, StockFit bridges this gap. With a comprehensive suite of features including fundamentals, ownership data, ETF and mutual fund exposure, insider transactions, and filings, StockFit ensures that every data point is directly pulled from SEC XBRL filings. This eliminates the risk of inaccuracies associated with derived data layers, allowing users to trace every number back to its original source. StockFit is built for real-world applications, expertly handling amended filings and fiscal years that do not align with the calendar. The API is equipped with rich economic models that dissect company offerings, competitor dynamics, and strategic initiatives, making it an invaluable resource for financial analysis and investment decision-making. With over 250 million facts and 5 million filings updated daily, StockFit API is ideal for those seeking reliable, model-ready financial data without compromise.
