WordStream's Keyword Tool API Offerings - Drupal
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!
