SEC EDGAR API
A free governmental API providing programmatic access to US public company filings, submissions, and structured XBRL financial data.
About SEC EDGAR API
The SEC EDGAR (Electronic Data Gathering, Analysis, and Retrieval) API is a free suite of RESTful endpoints provided by the US Securities and Exchange Commission. It allows developers to programmatically access regulatory filings and corporate financial disclosures made by publicly traded companies.
The API exposes deep historical and current financial data, utilizing structured XBRL (eXtensible Business Reporting Language) formats to standardize financial reporting metrics like company facts, income statements, and balance sheets.
Unlike commercial aggregators, the EDGAR API serves as the primary, authoritative source of US corporate financial data. Developers can retrieve massive bulk datasets, query individual company submission histories via Central Index Key (CIK), and pull real-time filing data. Usage is entirely free but requires standard User-Agent header formatting and adherence to fair-access rate limits.
