The service provides categorization of website by domains according to the provider's classification scheme. It evaluates a website as a whole, rather than page by page, to assign an overall classification from a taxonomy of website topics. Where a website addresses multiple categories, the service provides a rating of the site's relevance for each one.
API methods support submission of a website URL for analysis. The API returns one or more suggested categorizations based on the service's topic taxonomy with a relevance score for each. Returned data also indicate if the content identifies the URL as an adult site.
