+API Reference
+=============
+
+Overview
+========
+
+``spp-ctl`` provides simple REST like API. It supports http only, not https.
+
+Request and Response
+--------------------
+
+Request body is JSON format.
+It is accepted both ``text/plain`` and ``application/json``
+for the content-type header.
+
+Response of ``GET`` is JSON format and the content-type is
+``application/json`` if the request success.
+
+If a request fails, the response is a text which shows error reason
+and the content-type is ``text/plain``.
+
+Error code
+----------
+
+``spp-ctl`` does basic syntax and lexical check of a request.
+
++------+----------------------------------------------------------------+
+| Error| Description                                                    |
++======+================================================================+
+| 400  | Syntax or lexical error, or SPP returns error for the request. |
++------+----------------------------------------------------------------+
+| 404  | URL is not supported, or no SPP process of client-id in a URL. |
++------+----------------------------------------------------------------+
+| 500  | System error occured in ``spp-ctl``.                           |
++------+----------------------------------------------------------------+
+
+
+API independent of the process type
+===================================
+
+GET /v1/processes
+-----------------
+
+Show the SPP processes connected to the ``spp-ctl``.
+
+* Normarl response codes: 200
+
+Response
