From their site: The Digg Application Programming Interface (API) has been created to let users and partners interact programmatically with Digg. Digg is a place for people to discover and share content from anywhere on the web. From the largest sties to the smallest blogs, Digg surfaces the best stuff as voted on by users. The API returns Digg data in a form that can be integrated into an application or a web site. The API is available to everyone free of charge, but its use is subject to acceptance of the API License Agreement.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
Net::Digg is a library that provides an interface to the Digg API from PERL code. This library uses LWP internally, meaning that environment variables supported by LWP should also be supported by Net::Digg.
