Alpha Vantage is a data service that offers a free entry level data service and several premium paid membership levels. To use Alpha Vantage, you need to sign up and get a free API Key. The free data service has some basic limits. There can be 5 calls to the Alpha Vantage server per minute and a total of 500 calls per day.
