Exactly, I need balance sheet, income statement, cash flow statement, stock market, bankruptcy situation, fraud situation and corporate governance data of companies in USA.
I hope this helps - the Core US Fundamentals database on Quandl (https://www.quandl.com/data/SF1) covers 6,500+ companies, point-in-time, inc/exc restatements, active/delisted, up to 11 years history, 101 indicators, expanding coverage, daily updates. There's data for balance sheets, income statements, cash flow etc.
I am not sure if all companies you are looking for will be listed there but SEC-filing entities must file their reports to EDGAR (Electronic Data Gathering, Analysis, and Retrieval system). This system is available for use by the general public.
