• libcurl
• nlohmann/json
• Viewdns API Key

Install on Linux (Ubuntu):

sudo apt-get update
sudo apt-get install libcurl4-openssl-dev

Parameters:

1-) -u <domain>: The domain name (e.g., google.com)
2-) -a <apikey>: ViewDNS API key
3-) -o <output.txt>: The name of the output file (e.g., output.txt)
