No result for whoxy

[cosad3s]

The command returns no result:

❯ python3 related-domains.py -d blablacar.com -k $MYKEY

I think this is because whoxy API usage is not free: https://www.whoxy.com/pricing.php#whois

In fact, if we displayed the HTTP result, we get: {'status': 0, 'status_reason': 'Zero Account Balance'}

So credits should be added to the Whoxy account, I think it should be at least specified in the README.md.
