# Apache Zeppelin Interpreter REST API

<div id="toc"></div>

## Overview
Apache Zeppelin provides several REST APIs for interaction and remote activation of zeppelin functionality.
All REST APIs are available starting with the following endpoint `http://[zeppelin-server]:[zeppelin-port]/api`. 
Note that Apache Zeppelin REST APIs receive or return JSON objects, it is recommended for you to install some JSON viewers such as [JSONView](https://chrome.google.com/webstore/detail/jsonview/chklaanhfefbnpoihckbnefhakgolnmc).

If you work with Apache Zeppelin and find a need for an additional REST API, please [file an issue or send us an email](http://zeppelin.apache.org/community.html).

## Interpreter REST API List

The role of registered interpreters, settings and interpreters group are described in [here](../interpreter/overview.html).
