Adds some Multisite-specific functions to WordPress’ XML-RPC interface (http://yourdomain.com/xmlrpc.php).
Using this plugin, you can create a blog, update the archived status and get a blog ID using a remote software (another server, a desktop software, a mobile software…)
The functions enabled by this plugin are:
<ul>
<li>Create Blog (ms.CreateBlog)</li>
<li>Get Blog Id (ms.GetBlogId)</li>
<li>Update Archived (ms.UpdateArchived)</li>
</ul>

Multisite XML-RPC

Adds some Multisite-specific functions to WordPress' XML-RPC interface.

Walter Ebert

This plugin does more than just using the <code>xmlrpc_enabled</code> hook, because that is only used “To disable XML-RPC methods that require authentication”.
Activating this plugin will also disable pingbacks, trackbacks, and Really Simple Discovery (RSD), because these rely on XML-RPC.
It works with any webserver, because it does not use the .htaccess file.
<h4>Testing the plugin</h4>
From the command line you can test if the plugin is working correctly using <a href="https://curl.haxx.se/" rel="nofollow ugc">cURL</a>. Replace the <code>example.com</code> link to match your website:
<pre><code>curl -d '<?xml version="1.0"?><methodCall><methodName>system.listMethods</methodName><params><param><value><string/></value></param></params></methodCall>' https://example.com/xmlrpc.php
</code></pre>
This should only return the following methods: 
– <code>system.multicall</code> 
– <code>system.listMethods</code> 
– <code>system.getCapabilities</code>

Remove XML-RPC Methods

Remove all WordPress methods from the XML-RPC API to increase security.
