Developers: make $500 playing with APIs

My company Vonage pays developers $500 for a blog post. No catches.

We're interested in both technical tutorials and general pieces on programming. Successful submissions will be:

Original. Literally, we want original work (nothing that has been published elsewhere). And more figuratively, we want to see original thought and interesting points of view we can't find anywhere else.

Well-written. Our standards are high, and we want everything published on our blog to meet those standards. That said, you don't have to be a professional writer to submit! If the post is original, helpful and interesting, our editorial team is happy to work with you to get it publication ready.
