An API is an HTTP handler with accompagnying predicate, but unlike applications (see ../applications), APIs are targetted on machine-to-machine interaction. The response-type from an API is typically either XML or JSON.
The choice between XML and JSON is sometimes described by standards. JSON is often the preferred format if the intended client is a web-browser (using AJAX interaction).
