What are link redirect services?

Question

Link Shortening

Hello!
I have a link, I need to change the link address to any random one, so that it would redirect to mine.
It is necessary that the new redirect link live for a long time, at least a month. I have a couple of dozen such links a week, and new links should always be different, i.e. randomly generated (were completely unique).
It is desirable that it be some kind of service, even if it is paid. Like I went in, put in my own, got the generated one and use it without restrictions.
