my @data = decode_json($response); is a big red flag. JSON's decode_json function doesn't return a list. It always returns a single scalar. This scalar will be a reference to either an array or a hash.

Assigning a scalar value to the array variable @data is not wrong per se, but all it does is set the array to be a single-item array (hence the appearance of foreach "not working").

In this case, it appears to be returning a reference to a hash.

Try something like this:

my $data = decode_json($response);

printf(
   "'%s' was released in year %d and it is rated %s.\n",
   $data->{title},
   $data->{year},
   $data->{rating},
);
