title: Google custom search - limit exceeded error on first request?
body: <p>I've just signed up for the google custom search api, and have defined my engine using the control panel, and edited it as described in this answer: <a href="https://stackoverflow.com/a/11206266">https://stackoverflow.com/a/11206266</a>.  I then headed over to <a href="http://developers.google.com/apis-explorer/#p/customsearch/v1/search.cse.list" rel="nofollow noreferrer">http://developers.google.com/apis-explorer/#p/customsearch/v1/search.cse.list</a> in order to test the JSON API as described in the (fairly poor) documentation.  I pasted a simple query in the 'q' field and my search engine ID from the control panel in the 'cx' field, and then in the 'fields' section I selected all of the possible response types, but I'm getting the following result for any query I attempt:</p>
  
  <pre><code>{
   "error": {
    "errors": [
     {
      "domain": "usageLimits",
      "reason": "dailyLimitExceeded",
      "message": "Daily Limit Exceeded"
     }
    ],
    "code": 403,
    "message": "Daily Limit Exceeded"
   }
  }
  </code></pre>
  
  <p>Why has my daily limit been exceeded when I only signed up for the service 10 minutes ago and have not yet issued any requests?</p>
