AWIS provides the following operations, or "actions":

URL Information
The URL Information action gives developers direct access to information pertaining to web pages and sites on the web that Alexa Internet has gathered through its extensive web crawl and web usage analysis. Examples of information that can be accessed are site popularity, related sites, detailed usage/traffic stats, supported character-set/locales, and site contact information. This is most of the data that can be found on the Alexa web site and in the Alexa toolbar, plus additional information that is being made available for the first time with this release.

Historical Traffic
The Historical Traffic action gives programmatic access to web site traffic rank, reach, and page views going back one year. Use this action to compare a web site’s popularity over time, identify trends, or display graphs of traffic

Sites Linking In
The Sites Linking In action returns the sites linking to a specified web site.

Browse Categor
The Browse Category action allows developers to access all of the information available at the Open Directory without the need to download or host the directory database on their own systems. This service returns web pages and sub-categories within a specified category. The returned URLs are filtered through the Alexa traffic data and then ordered by popularity
