StockFit API

The API delivers structured financial data extracted directly from SEC EDGAR filings, covering income statements, balance sheets, cash‑flow statements, earnings, IPO S‑1 prospectus details, and ETF holdings. Each metric is timestamped to its filing, normalized across companies, and refreshed daily, providing point‑in‑time accuracy suitable for quantitative modeling and backtesting. The service also includes ownership information such as institutional 13F holdings, insider transactions, and share‑class data, as well as a news feed and symbol lookup across multiple identifiers.

Designed for developers, the endpoints expose raw XBRL‑derived numbers alongside derived metrics like growth rates, health scores, and quality indicators (e.g., Altman‑Z, Piotroski‑F). Additional APIs classify business models, summarize earnings calendars, and capture executive compensation and governance flags, all sourced from official SEC documents without adjusted figures.

The platform emphasizes traceability and auditability, offering an audit trail for every reported value and compatibility with AI assistants through an API key. It targets quantitative researchers, backtesting engineers, and financial analysts who need reliable, SEC‑sourced data for modeling, screening, and automated workflows.
