title: Youtube REST API v3 - include statistics for video in search query result
body: <p>I want to perform search queries using Youtube API v3.
  What I need is to retrieve video ids and statistics for each video.
  From the <a href="https://developers.google.com/youtube/v3/docs/search#resource">docs</a> I can see that statistics is not returned for video items. If I try to ask for statistics using this query:</p>
  
  <pre><code>https://www.googleapis.com/youtube/v3/search?type=video&amp;part=snippet,statistics&amp;q=kittens&amp;key={MY_KEY}
  </code></pre>
  
  <p>I receive an error:</p>
  
  <pre><code>{
   "error": {
    "errors": [
     {
      "domain": "youtube.part",
      "reason": "unknownPart",
      "message": "statistics",
      "locationType": "parameter",
      "location": "part"
     }
    ],
    "code": 400,
    "message": "statistics"
   }
  }
  </code></pre>
  
  <p>So I guess that I need to make two requests:</p>
  
  <ol>
  <li>Perform actual search and retrieve list of video ids.</li>
  <li>Make API request <a href="https://developers.google.com/youtube/v3/docs/videos/list">https://developers.google.com/youtube/v3/docs/videos/list</a> to retrieve statistics for each video.</li>
  </ol>
  
  <p>Or maybe I'm missing something and there's a way to get statistics for videos within one search query?</p>
