title: CEP: source for real-time events or data feeds?
body: <p>I am searching for free event sources that I can use within my java-application.
  I am looking for something similar to <a href="http://finance.yahoo.com" rel="nofollow noreferrer">YahooFinance</a>, where one can query a bunch of stock info and retrieve the result as csv.</p>
  <p>Ideally, an API or a URL with some query string would be perfect.</p>
