Program to get Minecraft names?

As you know, you can change your name every month. I would like to have a name that is often changed for money. Is there a program that can check the availability of the name and take it automatically if it is free? Maybe a website too?

You can write something for yourself. For example, NameMC has ne api and Mojang too

Yes, that would be fine, but for that I would have to be online all the time and the page certainly takes a while to update the names.

I mean that you are a programmer what that does

How did you come up with that? If that were possible, I would already be rich. Your question has no logic.

The names that are actually sold on certain forums for a lot of money (between 300 and 1500 euro, depending on the name) were registered by Minecraft in the early days. By that I mean names like Twitter or legendary three-letter names.

Yes, but these names are not changed that often. It's so common with my name.

Besides, it would still work if I was fast enough
