title: Lookup Twilio Docs Example is not working. Returning a 404?
body: <p>I'm attempting to use the Twilio Lookup service, purely the validate and format numbers into international format (even without having the original country code)</p>
  <p>This is the Twilio example, with a slight modification, seen in their docs:</p>
  <pre><code>    TwilioClient.Init(accountSid, authToken);
  
      var type = new List&lt;string&gt; {
     &quot;national_format&quot;
      };
  
      var phoneNumber = PhoneNumberResource.Fetch(
          type: type,
          pathPhoneNumber: new Twilio.Types.PhoneNumber(&quot;07738629111&quot;)
      );
  
      Console.WriteLine(phoneNumber.NationalFormat);
      return phoneNumber.NationalFormat;
  </code></pre>
  <p>Errors, with the following</p>
  <blockquote>
  <p>{&quot;The requested resource /PhoneNumbers/07738629111 was not found&quot;}</p>
  </blockquote>
  <p>Yet, this is the same as <a href="https://www.twilio.com/docs/lookup/api" rel="nofollow noreferrer">Twilio docs</a>... furthermore, my accountSid and authToken are correct, as I'm using the API doing something else.</p>
  <p>Could this possibly be a coding issue, and does anybody know how to solve it?</p>
