Earnings Report returns a company's complete financial statements - income statement, balance sheet and cash flow together - in a single call from SEC filings, making it a one-stop earnings API for fundamental stock data. Look up by ticker or CIK; paid plans add calculated margins and year and quarter filters. For a single focused statement, see the Income Statement, Balance Sheet, Cash Flow and Financial Ratios APIs.
