The Example API is a bit of a weekend project of mine aimed mostly at exploring different data types and interactions on a node + express based server. It's a quick tool to aid developers in creating web applications. The Example API will take a query and return any kind of data desired. It's very useful for testing application logic, particularly javascript, where you have logic that is already written but don't have a fleshed out API server-side that can respond appropriately.
The Example API can respond with any popular textual data type(other media to come soon) to GET requests and will also soon respond appropriately to other HTTP methods. If you don't need data but you do need to get a certain response code back, you can request it just by directing your query to http://exampleapi.com/status/<the status code>.
The Example API project is hosted on GitHub(please forgive the mess left over from my dependency kerfuffle) and the website is live at http://exampleapi.com where much more detailed information is available.
