XF 2.0 How to access XenForo options via regular PHP

[BlueOrange]

EDIT: I've managed to solve this myself, by looking around the forums and seeing what is done for people creating threads and users via "external" scripts. My solution is:

function GetAPIKey() {
    $dir = $_SERVER["DOCUMENT_ROOT"];
    require("$dir/src/XF.php");

    XF::start($dir);

    $options = XF::options();
    return "$options->BridgeAPIKey";
}

I've been developing a API of sorts and within this API I would like to get the options from a custom addon. How would I do so?
I've tried the following, but nothing is returned when GetAPIKey is called:

public static function GetAPIKey() {
    $options = \XF::options();
    return $options["BridgeAPIKey"];
}

public static function GetAPIKey() {
    $options = \XF::options();
    return $options->BridgeAPIKey;
}

Am I missing something? The option was created in the addon options in debug mode too.

Thanks

You might consider separating out some of the code. It's good to use the SOLID principle and have one purpose for each method. Also, you'll want a catch for an error if the directory is wrong. The code below doesn't return an error message but it might be a good idea.

Without spending too much time, this is similar to your code but sets a method for the connection as well as a method for getting the Bridge API Key.

class AClassNameGoesHere {

   protected $options;

   public function construct() {

   }

   public function GetXF() {

      // What happens when XF is in a subdirectory off the root?
      $fileDir = $_SERVER["DOCUMENT_ROOT"];

      if ( ! file_exists( $fileDir . '/src/XF.php'  ) ) {
         return false;
      }

      require( $fileDir . '/src/XF.php' );
      \XF::start($fileDir);

      $app = \XF::setupApp('XF\Pub\App');
      $app->start();

      return '';
   }

   public function GetBridgeAPIKey(){

      if ( ! class_exists( '\XF' ) ) {
         $this->GetXF();
      }
      $this->options = \XF::options();
      return "$this->options->BridgeAPIKey";
   }
}
