title: Is it possible to fetch data from an api with cloud funtions of Firebase?
body: <p>I'm thinking about mobile app project that takes data (News) from an api provider into Firebase real-time database so that later when users search for 
  News they get it from my Firebase database .
  The question is that , can I do this work just by using cloud functions ?
  If not ,could you please provide an alternative and why?</p>
