If you set up an account with us to sell your API(s), we'll charge $5/month for the account. If you don't make any sales, then the most you'll ever pay out of pocket is the $5.

Once you start making revenue, you'll get a $5 credit towards the revenue share each month. In other words, it ends up being the greater of $5 or 22% of total revenue. Hope that helps!

I find it easier to read if it's something like "22% with $5 minimum per month".
