Are there ready-made solutions for quickly checking whois domains through a proxy (from 1000 domains per second)?

Question

Domain Name System

Good day!
Is there a ready-made solution for quickly checking millions of domains for whois, naturally, using a proxy?
Fast is from 1000 per second when using public proxies or tor nodes.
A built-in proxy prioritizer is desirable.
The implementation language does not matter.
Thanks

If you are a partner of nic.ru, for example, then you can get all domains in one file at once.
All information at once.
