Manipulating/view postmeta remotely

You can modify the arguments of the post type to enable the REST API:

function wpd_tribe_events_args( $args, $post_type ) {
    if ( 'tribe_events' == $post_type ) {
        $args['show_in_rest'] = true;
    }
    return $args;
}
add_filter( 'register_post_type_args', 'wpd_tribe_events_args', 20, 2 );
