About StockFit API
StockFit API gives developers, quants, and research platforms direct access to SEC filing data without the usual tradeoffs. Most financial APIs force you to choose between cheap tiers with accuracy issues or enterprise contracts that drain a startup's budget. StockFit fills the gap: fundamentals, ownership, ETF/MF exposure, insider transactions, and filings - all pulled directly from SEC XBRL, no derived middle layer, every number traceable back to the original filing. Built for real use: amended filings are handled, non-December fiscal years computed correctly, Q4 reconstructed from 10-K + 10-Q. Rich economic models per company cover offerings, peers, operating levers, competitive advantages, flywheels, strategic initiatives, and failure modes. ETF/MF exposure models cover mandate, portfolio construction, costs, sensitivities, and use cases - AI-friendly for LLM workflows. 250M+ facts, 5M+ filings, updated daily. REST API plus native MCP server for Claude, Cursor, and other AI tools
