Hi first thanks for your time, I used the following code

#!/usr/bin/perl -w


use feature 'say';
use Mojo::UserAgent;

my $ua = Mojo::UserAgent->new;

my $coinbaseURL = 'https://api.coindesk.com/v1/bpi/currentprice/usd.js
+on';
my $value = $ua->get( $coinbaseURL )->result->json->{bpi}{USD}{rate};
#say "Bitcoin Price (USD): $value";
print "Content-Type: text/html\n\n"; 
print "Bitcoin Price (USD): $value";

But I got the following error :

[error] [client 127.0.0.1] IO::Socket::SSL 2.009+ required for TLS sup
+port at /home/alexandre/apache/cgi-bin/helloWorld.cgi line 10.

EDIT : After upgrading IO::Socket::SSL it's work fine thanks you guys
