<h1 id="querying-media"><a class="header" href="#querying-media">Querying media</a></h1>
<p>These APIs allow extracting media information from the homeserver.</p>
<h2 id="list-all-media-in-a-room"><a class="header" href="#list-all-media-in-a-room">List all media in a room</a></h2>
<p>This API gets a list of known media in a room.
However, it only shows media from unencrypted events or rooms.</p>
<p>The API is:</p>
<pre><code>GET /_synapse/admin/v1/room/&lt;room_id&gt;/media
</code></pre>
<p>To use it, you will need to authenticate by providing an <code>access_token</code> for a
server admin: see <a href="../usage/administration/admin_api">Admin API</a>.</p>
<p>The API returns a JSON body like the following:</p>
<pre><code class="language-json">{
  &quot;local&quot;: [
    &quot;mxc://localhost/xwvutsrqponmlkjihgfedcba&quot;,
    &quot;mxc://localhost/abcdefghijklmnopqrstuvwx&quot;
