Good stuff - that caching simplifies what I have to do as I then don't have to worry if I am hitting the server too often.

Here's some example code from the xchange-examples jar to demonstrate using the api key and requesting the data from OpenExchangeRates:

Code:

// Use the factory to get the Open Exchange Rates exchange API
   ExchangeSpecification exchangeSpecification = new ExchangeSpecification("com.xeiam.xchange.oer.OERExchange");
   exchangeSpecification.setUri("http://openexchangerates.org");
   exchangeSpecification.setApiKey("ea88c922bca263ba9345b4717914ee1f");
   Exchange openExchangeRates = ExchangeFactory.INSTANCE.createExchange(exchangeSpecification);

   // Interested in the polling market data feed
   PollingMarketDataService marketDataService = openExchangeRates.getPollingMarketDataService();

   // Get the latest ticker data showing EUR/USD
   Ticker ticker = marketDataService.getTicker(Currencies.EUR, Currencies.USD);
   System.out.println("Last: " + ticker.getLast().toString());

   // Request another ticker JPY/USD. it will return a cached object
   ticker = marketDataService.getTicker(Currencies.JPY, Currencies.USD);
   System.out.println("cached Last: " + ticker.getLast().toString());

...and the result...

Code:

Last: EUR 0.752646
cached Last: JPY 88.740257
