This is a very common pattern with SAAS: instead of giving you a price, they ask you to request a trial or demo. Sometimes you will find the price hidden somewhere on the website, but most of the time there is no price at all.
An example of this can be found at https://www.usertesting.com/ (see image below)
I know why this is done, I know the benefits to the companies and I know it is a dark pattern. What I do not know is the name for this pattern. I did a Google search and found many pages with examples, but no naming convention.
Does it have a specific name?
