title: Foursquare API request returning error on version parameter
body: <p>I am trying to send a get request to the Foursquare developer API to get a json response of all nearby venues through the "explore" feature. The error I am getting reads, </p>
  
  <pre><code>{'meta': {'code': 410,
    'errorType': 'param_error',
    'errorDetail': '**The Foursquare API no longer supports requests that pass in a version v &lt;= 20120609.** For more details see https://developer.foursquare.com/overview/versioning',
    'requestId': '5d9f5d5fcad1b6002c61ef2c'},
   'response': {}}
  </code></pre>
  
  <p>My input code is as follows:</p>
  
  <pre><code>LIMIT = 50
  RADIUS = 16093.4
  VERSION = 'YYYYMMDD'
  
  url = 'https://api.foursquare.com/v2/venues/explore?&amp;client_id={}&amp;client_secret={}&amp;v={}&amp;ll={},{}&amp;radius={}&amp;limit={}'.format(CLIENT_ID, CLIENT_SECRET, latitude, longitude, VERSION, RADIUS, LIMIT)
  
  results = requests.get(url).json() 
  </code></pre>
  
  <p>The results output is where I am getting the error.</p>
  
  <p>I have tried multiple different dates for the VERSION variable, such as '20191008' , '20181008', etc. and all give me the same error. </p>
