WASP RESTful API

This documentation explain all the exposed services of WASP system. Via the APIs is possible to access and manage every element of the system. All the APIs return a response using JSON format, like below. At the moment is the only supported format. This is the first version of this documentation and the APIs are currently work in progress. In the next future we will make improvements at the system and consequently at the APIs. Below you can find all the APIs associated with the supported HTTP verbs.
