The default MetaMe API url is http://+:80/Temporary_Listen_Addresses/MetaMe/api.
From version 0.20.1, you can change this url by going to Settings > General and changing the
--url parameter. Click “SAVE & RESTART” to save the settings and restart.
The url prefix “+” or “*” must be used in place of “localhost”
*Please note that MetaMe will require appropriate permissions for this. See how to host MetaMe API on a different port for more detail.
