This application uses the AlphaVantage API. Setup a free account with them to use this application. Create a file called apikey.json and create a single json key value pair with "api_key" being the key and the value being your api key as shown below. DO NOT TRACK YOUR apikey.json FILE. It's generally considered good practice to always hide your API key. { "api_key" : "<YOUR API KEY GOES HERE>" }
