title: CSGO Get players items
body: <p>For a little project, I want to get a list of all CSGo player's items.
  I'm using steam web API:</p>
  
  <pre><code>https://api.steampowered.com/IEconItems_730/GetPlayerItems/v1/?key=*****&amp;format=json&amp;steamid=********
  </code></pre>
  
  <p>I get a HTTP 503, I'm sure that the key and the steam id exists..
  The HTML:</p>
  
  <pre><code>&lt;html&gt;&lt;head&gt;&lt;link rel="alternate stylesheet" type="text/CSS" href="resource://gre-resources/plaintext.css" title="Retour à la ligne automatique"&gt;&lt;/head&gt;&lt;body&gt;&lt;pre&gt;{
  
  }&lt;/pre&gt;&lt;/body&gt;&lt;/html&gt;
  </code></pre>
  
  <p>Also when I try with </p>
  
  <pre><code>https://api.steampowered.com/IEconItems_440/GetPlayerItems/v1/?key=*****&amp;format=json&amp;steamid=******** 
  </code></pre>
  
  <p>It works!</p>
