The CLOUDFLOW API exists in various forms.

As a JSON-RPC
As a JS API
As a PHP API
As a cURL call

You can find the API reference on http://<server>:<port>/?api

JSON-RPC
The CLOUDFLOW API uses JSON-RPC to communicate with the back end, a remote procedure call protocol which uses HTTP as the transport protocol and JSON as the encoding.
JS and PHP layers
For ease of use, there are two thin layers available on top of the JSON-RPC over HTTP API.
cURL
cURL is a command line tool that can perform HTTP requests (https://curl.haxx.se/). With this tool the low level JSON over HTTP API of CLOUDFLOW is exposed.
