title: Get length of videos calling youtube playlist API (v3)
body: <pre class="lang-js prettyprint-override"><code>$http.get("https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&amp;playlistId=PLFgquLnL59alCl_2TQvOiD5Vgm1hCaGSI&amp;key={mykey}&amp;maxResults=10")
  </code></pre>
  
  <p>I used the <code>playlistItems</code> but couldn't get the statistic part which contain duration of the video. Do I need to call twice? Get the video Id and make another call? or I'm missing something in this case?</p>
