We have created some example apps using the Embedly API that can be used for instructive purposes. The source for these apps can always be found on our github page. We usually accompany our example apps with a post on our blog.
Embedly libraries for various programming languages are provided on our github page in the form of Embedly-$lang. Each of the Embedly libraries contain example code snippets in their documentation. The library documentation is either contained or referenced in the projects README file. If you don’t see your language of choice, then feel free to request a client library for your language via firstname.lastname@example.org.
