G'day joyfedl,

You seem to be thinking along correct lines. I didn't look too deeply at your detailed code. I think you probably want something like:

$ perl -E '
    my @lives = (1, 2, 3);
    my $url_base = "https://v3.football.api-sports.io/fixtures?live=";
    for my $live (@lives) {
        my $url = "$url_base$live";
        say "Do stuff with $url";
    }
'
Do stuff with https://v3.football.api-sports.io/fixtures?live=1
Do stuff with https://v3.football.api-sports.io/fixtures?live=2
Do stuff with https://v3.football.api-sports.io/fixtures?live=3
