The Easy API is one of the fastest growing API services out there. We offer a service that allows you to use multiple API's without having to code for the specific interfaces. An example would be that we have both a Zip Code Radius location tool, and also offer SEOMoz. Instead of coding two different application methods, you just have to code one. One easy to use API that can do the work of all the others. It accepts a POST then will return well formed XML. We are going to be offering JSONP->JSON integration in 2011.
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.
