A Java wrapper to get stock data and stock indicators from the Alpha Vantage API.
Alpha Vantage delivers a free API for real time financial data and most used finance indicators. This library implements a wrapper to the free API provided by Alpha Vantage (https://www.alphavantage.co/). It requires an api key, that can be requested on https://www.alphavantage.co/support/#api-key. You can have a look at all the api calls available in their documentation https://www.alphavantage.co/documentation.

}Now that you set up your project and have your api key you can start using the service. Here are a few examples of how you can use the service.
public class App {
public static void main(String[] args) {
String apiKey = "50M3AP1K3Y";
int timeout = 3000;
AlphaVantageConnector apiConnector = new AlphaVantageConnector(apiKey, timeout);
TimeSeries stockTimeSeries = new TimeSeries(apiConnector);
try {
IntraDay response = stockTimeSeries.intraDay("MSFT", Interval.ONE_MIN, OutputSize.COMPACT);
Map<String, String> metaData = response.getMetaData();
System.out.println("Information: " + metaData.get("1. Information"));
System.out.println("Stock: " + metaData.get("2. Symbol"));
List<StockData> stockData = response.getStockData();
stockData.forEach(stock -> {
System.out.println("date: " + stock.getDateTime());
System.out.println("open: " + stock.getOpen());
System.out.println("high: " + stock.getHigh());
System.out.println("low: " + stock.getLow());
System.out.println("close: " + stock.getClose());

});
