If you can work with a model with just two regions (north and south), I have made some minor changes to handle this:

#!/usr/bin/env perl
use Mojolicious::Lite -signatures;


get '/' => sub ($c) {
  $c->render(template => 'index');
};

get '/api/:region' => sub ($c) {
  my %regions = (
    north => {
      countries => [
        'Antigua and Barbuda',              'Bahamas',
        'Barbados',                         'Belize',
        'Canada',                           'Costa Rica',
        'Cuba',                             'Dominica',
        'Dominican Republic',               'El Salvador',
        'Grenada',                          'Guatemala',
        'Haiti',                            'Honduras',
        'Jamaica',                          'Mexico',
        'Nicaragua',                        'Panama',
        'Saint Kitts and Nevis',            'Saint Lucia',
        'Saint Vincent and the Grenadines', 'Trinidad and Tobago',
        'United States',
      ],
      region => 'North America',
    },
    south => {
      countries => [
        'Argentina', 'Bolivia',  'Brazil',  'Chile',
        'Colombia',  'Ecuador',  'Guyana',  'Paraguay',
        'Peru',      'Suriname', 'Uruguay', 'Venezuela',
      ],
      region => 'South America',
    },
  );

  my $region = $regions{$c->param('region')} || {};
  $c->render(json => $region);
};

app->start;
