The Comments API contains functions for working with user-created comments, as applied to media. This includes initially creating comments, retrieving comment information, editing comment text, and altering comment status. As with other APIs, the scope of this one is the current partner.
The Crypt API contains functions for working with encryption. This API makes it possible for the partner to encrypt and decrypt strings of content, and to obtain the necessary encryption key for doing this.
The Genre API contains functions for working with genres. Genres are themes under which various kinds of content fall. Genres might include "News", "Lifestyle", "Television", "Weather", and "Images for this Week".
The Media API is a very large API that contains functions for dealing with media and media requests. These include retrieving pieces of media and information about media, altering various media attributes, generating tokens that make it possible to run/display media, and other useful things.
The Ratings API contains functions for dealing with ratings. This includes creating and working with ratings, rating groups, and rating systems. A rating group is best described as a property, or quality possessed by some entity such as a piece of media; something that a user might wish to evaluate. A rating system is the scale by which the user would evaluate the media, very similar to a grade or score. Common examples of this are rating movies or books on a scale of 1 to 5 stars for such qualities as originality or pure enjoyment, or restaurants for food and ambiance. Another, simpler rating system could take the form of a basic approval/disapproval, or "thumb's up", "thumb's down" rating system.
The ReportedPost APIs are used to "flag" a target for further review. A target could be a piece of media, a comment or nearly anything else. This functionality is generally used in lieu of an approval queue process. The advantage is that the content that would be screened becomes live a lot quicker and you "crowdsource" the review process. The downside, of course, is that there is a potential that the community will not flag offending content.
Allows for the retrieval of statistics and analytics related to media playback. If you are looking for APIs that return most popular (played) media or highest rated media, look under the "Stats" APIs for the appropriate services.
