title: How to access Google client api without Oauth (just API key)
body: <p>I am trying to access Google api client (Ruby) without Oauth..
  I have found this info:</p>
  
  <p><a href="http://thecodeabode.blogspot.com.au/2012/07/google-api-ruby-client-authorizing-with.html" rel="nofollow">http://thecodeabode.blogspot.com.au/2012/07/google-api-ruby-client-authorizing-with.html</a></p>
  
  <p>But unfortunately, if I follow the instructions (Here is what  I do):</p>
  
  <pre><code> require 'google/api_client'
   client = Google::APIClient.new(:key =&gt; "MYKEY",:authorization =&gt; nil)    
   yt = client.discovered_api("youtube", "v3")
   result = client.execute(
     :api_method =&gt; yt.search.list,
     :parameters =&gt; {
       :key =&gt; "MYKEY",
       :q =&gt; "dogs",
       :part =&gt; "topicDetails"
     }
   )
  </code></pre>
  
  <p>I get </p>
  
  <p>"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup"</p>
  
  <p>What is wrong?</p>
