Free License Key via plugin

When calling your code from wfConfig.php to get a free license key it now returns an error.

Code:

$keyData = $api->call('get_anon_api_key');

Error:

The Wordfence scanning servers are currently unavailable. This may be for maintenance or a temporary outage. If this still occurs in an hour, please contact support

Is this a temporary thing or are you doing away with being able to get a free license key solely via the plugin?
