Data for over 75,000 stocks as found at the Yahoo Finance website, transformed into convenient JSON format. This API provides a transformation service, but is not responsible for the data itself (all of which is already freely available in CSV / HTML from the website). The purpose of this API is to make the querying of the data more convenient, and the API authors encourage API consumers to show support for Yahoo by purchasing a paid subscription to access their Premium services.
Fundamentals data is available as per the Yahoo site - this is typically yearly and quarterly statements, for cash flows, income statement, balance sheet, and key financials, but there are cases (depending on exchange and/or specific company) where data is not available. A query to a missing data point will result in a 404 error. Refer to Yahoo for comparison.
Returns an ordered list of all available exchange codes (those codes that are known to be in use by Yahoo and have stocks mapped against them). It is suggested that you start by querying that endpoint to identify the exchange codes, then query for the exchanges that interest you for a list of stock tickers, and then subsequently, query their financial/price data.
Convient list of common stocks listed per exchange. This list is occasionally updated manually by the API maintainer, and so may not be fully representative of all available stocks on a day-to-day basis, but should help in stock discovery.
Query end of day quotes (open, high, low, close, adjusted close, volume etc) based on date rate (startDateInclusive/endDateInclusive in YYYY-MM-DD format)
