The web service offers a web filtering database of website profiles that aids in classifying sites. A request specifying a web URI receives information about the site, including its category from a list of almost 100 types maintained by the service. The site's reputation index is also provided. Developers can use the data to track web use and enforce internet-use policies.
Methods allow retrieval of a current category list, categories assigned to a particular URI, and real-time updates to the URI database. The API also allows reporting of URIs not yet categorized and suggestions for category changes.
