The ultimate is when you get a marketer who understands what APIs are used for. For example, I can say that the OP should probably consider pasting his sample code higher up on the page in a more prominent position. Show the end user he can succeed easily with the product and he won't mind clicking the sign-up button. Marketers these days also need to know where you can find these users. They should have an account here, SO, SlashDot, r/programming, Quora and so on.
