title: Can I restrict the usage of Cognitive Services API keys by some conditions?
body: <p>In Google Cloud platform, developers can restrict the usage of API keys by some conditions.</p>
  
  <p>For example,</p>
  
  <ul>
  <li>HTTP referrers</li>
  <li>IP Addresses</li>
  <li>Apps</li>
  </ul>

  <p>I'm wondering whether the developers can restrict Azure's API keys (i.e. Cognitive Services) like GCP's case.</p>
