The IttyUrl API lets you create short URLs and offers tagging, search, PageRank, and automatic RPC Ping services. Users of the main site shorten long URLs, but IttyUrl is different because it lets users create a free user account and then see all of their links, search for related content by tags found in multiple people's links, export results as RSS, and more. It also specializes in Silverlight links.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
