I've been building web apps for several years now and I still feel weary (though I've obviously learned to get over it) asking people to pay recurring amounts for services I've built. I'd have a hard time asking people to pay $5 (that's $60 a year!) for something that took me 3 days to build and relies 100% on an API I have no control over. Of course, this is not a criticism in the least; if anything I'm somewhat envious of your confidence. One thing that took me a while to learn is that the ONLY way to set pricing is by soliciting actual customer feedback, rather than going with your gut or deciding what you think is fair (hint: those don't work). So, good job having learned this so soon.
