Site search by mask?

Question

Search engines

The bottom line is that you need to collect a database of sites that would actually exist , and not just a busy domain.
You need to find sites by mask, and you need to find them with a maximum of domains, i.e. not only in the .ru .com .net zone, but in general everything, including even such exotic ones as .shop, etc.
And the search must be done by the mask in the name, for example, all sites that contain, for example, sberbank, avito, vk.
Most of all I liked letsearch so far, but it only searches for .ru domains, and you need as many domains as possible.
I need this to search for so -called clones, or phishing sites .
Are there ways to do this? Because the same whois is looking for the wrong thing to say the least.

Currently using CatPhishin Kali as well as URLCrazy .
But these programs do not allow you to check whether it is a site or just an available domain.
Does anyone know the script?
The coolest thing I found is OpenDNS Cisco Investigate, but the problem is that you just can’t register there, and for the script that I found, you need Api.
I will be grateful for any help.
