Show HN: Dead simple SMS API

Pretty cool, I just tried it and it worked. I didn't like how I had to send two requests with the same message, one before and one after opting in. Ideally after opting in I would have received the initial message. Otherwise any application would have to use polling.

For the code snippets you could use httpsnippet[1] or apiembed[2] to support some more languages.

Do you plan to post your API every 10 days?

It's a great service otherwise, but it would be nice to have more documentation.

I think there is a trailing \ too much in the curl example.

I can't test it, because I'm in Germany, but did you implement any rate limiting? It does look like everyone could send lots of text messages over your API.
