I have a list of 5000 words I would like automatically to check which ones are free as xxxx.com domain. Is there a free service to do so instead of copy/pasting thousands of times in register.com

I am not searching for an automated solution to make profit of it. I need to buy a domain for myself.

There are command-line tools like whois that will do the check; I'd just write a shell script to do that

You can also write a script to ping each of those then check who the response comes from. Some DNS servers resolve unregistered domains to a parking page at a registrar. If yours does that, just check for a mismatch with that IP address to find a domain that is unavailable. A match means you should be able to register it.

A number of whois/dig services are free, though ultimately the mitigating factor is going to be the throttling that you'll encounter with making requests. So long as you limit your queries to a number below the limit set by the provider, you'll do OK.
