<span class="sd">&quot;&quot;&quot;Torznab_ is an API specification that provides a standardized way to query</span>
<span class="sd">torrent site for content. It is used by a number of torrent applications,</span>
<span class="sd">including Prowlarr_ and Jackett_.</span>
<span class="sd">Using this engine together with Prowlarr_ or Jackett_ allows you to search</span>
<span class="sd">a huge number of torrent sites which are not directly supported.</span>
<span class="sd">Configuration</span>
<span class="sd">=============</span>
<span class="sd">The engine has the following settings:</span>
<span class="sd">``base_url``:</span>
<span class="sd"> Torznab endpoint URL.</span>
<span class="sd">``api_key``:</span>
<span class="sd"> The API key to use for authentication.</span>
<span class="sd">``torznab_categories``:</span>
<span class="sd"> The categories to use for searching. This is a list of category IDs. See</span>
<span class="sd"> Prowlarr-categories_ or Jackett-categories_ for more information.</span>
<span class="sd">``show_torrent_files``:</span>
<span class="sd"> Whether to show the torrent file in the search results. Be carful as using</span>
<span class="sd"> this with Prowlarr_ or Jackett_ leaks the API key. This should be used only</span>
<span class="sd"> if you are querying a Torznab endpoint without authentication or if the</span>
<span class="sd"> instance is private. Be aware that private trackers may ban you if you share</span>
<span class="sd"> the torrent file. Defaults to ``false``.</span>
<span class="sd">``show_magnet_links``:</span>
<span class="sd"> Whether to show the magnet link in the search results. Be aware that private</span>
<span class="sd"> trackers may ban you if you share the magnet link. Defaults to ``true``.</span>
