YorApi is a platform and service that allows developers to create REST APIs, host them on the YorApi platform and launch their mobile applications built on top of their own APIs. The YorApi API itself allows developers access to the functionality of the site in order to build tools that build APIs.
YorApi is in private beta; interested developers should sign up here: http://www.yorapi.com.
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.
