This is a solved problem. It's called a "demo". What it entails is giving a small sample of your product completely for free, with no monetization at all, in order to entice a prospective buyer for more. It may be less lucrative than selling microtransactions to literal children, but it is something that people won't complain about, if you are genuinely in the market for a solution and not just trying to farm money off of scamming kids into swiping their parents' credit card because they have no idea what it's worth.
