Wordstream stopped accepting new Drupal user registrations in September 2012. Those that had already registered were dropped in February 2013, so this is now a year past due.

WordStream Keyword API For Drupal
WordStream has enjoyed supporting the Drupal community, but as of September 2012, we are no longer accepting new registrations for our free keyword API.

We direct you to the other available Drupal module plug-ins for your keyword research needs: http://drupal.org/project/kwresearch

Existing free API users will be supported through February 2013.

Thanks again, everyone!
