+=========
+OCS API's
+=========
+
+This document provides a quick overview of the OCS API endpoints supported in Nextcloud.
+
+All requests need to provide authentication information, either as a Basic Auth header or by passing a set of valid session cookies, if not stated otherwise.
+
+
+----
+Testing requests with curl
+----
+
+All OCS requests can be easily tested out using :code:`curl` by specifying the request method (:code:`GET`, :code:`PUT`, etc) and setting a request body where needed.
+
+For example: you can perform a :code:`GET` request to get information about a user:
+
+
+.. code-block:: bash
+
+    curl -u username:password -X GET 'https://cloud.example.com/ocs/v1.php/...' -H "OCS-APIRequest: true"
+
+
+-------------
+User metadata
+-------------
+
+Since: 11.0.2, 12.0.0
+
+This request returns the available metadata of a user. Admin users can see the information of all users, while a default user only can access it's own metadata.
+
+.. code::
+
+	GET /ocs/v1.php/cloud/users/USERID
+
+
+.. code:: xml
+
+	<?xml version="1.0"?>
+	<ocs>
+		<meta>
+			<status>ok</status>
+			<statuscode>100</statuscode>
+			<message>OK</message>
+			<totalitems></totalitems>
