title: Get Youtube title from youtube without developer/api key
body: <p>Since april 2015 the old youtube api v2 is deprecated.</p>
  
  <p>I used this link to get the youtube title, which worked pretty good:</p>
  
  <p><a href="https://gdata.youtube.com/feeds/api/videos/video_id?v=2" rel="nofollow">https://gdata.youtube.com/feeds/api/videos/video_id?v=2</a></p>
  
  <p>instead of the title i get now the following link:</p>
  
  <p><a href="https://youtube.com/devicesupport" rel="nofollow">https://youtube.com/devicesupport</a></p>
  
  <p>Now the recommend to use the v3. To use this api, i have to generate a developer/api key. </p>
  
  <p>Is this really necessary just to get the youtube title of video?</p>
  
  <p>Is there another way to get the title without that key?</p>
