Stsh is a project mainly written in RUBY and JAVASCRIPT, it's free.
Stsh.me is both an endpoint to upload screenshots for a tinygrab-like client, as well as a url shortener.
If you would like to use stsh-client to upload your screenshots, just tell it to post to:
http://stsh.me/imagesIf you would like to use the currently hosted url shortener; just send an http POST request to http://stsh.me/ with a string as your param. This should work as a simple API for all platforms.
On POST a url will be returned to you to share to the rest of the world.
Example:
$ curl -d 'http://google.com/' http://stsh.me/
$ # => http://stsh.me/2d3Copyright (c) 2011 Jake Dahn
