Exposing custom content types meta data to REST API

[mrawers]

Is it possible to add the metadata from the custom content types to the WordPress REST API?
I am testing with a plugin that adds a few different custom content types and each content type has a metabox.php i.e. team.php and team-metabox.php. I was able to add the 'show_in_rest' => true, to the main content type but the metaboxes which use a function named: ot_register_meta_box is not paying attention to the show_in_rest attribute. Is what I am requesting possible?
