Seems like a super useful API. I don't know a much about the space, but I can't believe something like this doesn't exist.

I wanted to see a dead-simple demonstration on the website, couldn't find one. Perhaps it would be effective to demonstrate the API by sending a free app link via email. Just have a "Try it now! We'll show you how simple it can be by sending you a free app link to your email on signing up! ~ or something (reduce the copy language)

Keep it up!

PS - Is there potential for a referral/affiliate angle on this API? Apple's TOS probably prohibits that, but if it could somehow be managed--I see massive value there.
