Can I automatically query Copyscape Premium?
Using the Copyscape Premium API, you can automatically query the Copyscape service and receive results in XML format. Each API request is billed in the same way as a search performed through the regular Copyscape Premium interface. In order to use the API, simply sign up for Copyscape Premium, click on ‘Premium API’ in the ‘Copyscape Premium’ menu at the top, and then click on the ‘Activate API Access’ button. Complete instructions will then be provided.
