Submitting a story via passed variables, OExchange

My site would like to receive story submissions from AddThis.com. They use a protocol called OExchange to pass stories to destination sites like this:

http://www.example.com/share.php?url={URI}&title={title for the content}&description={short description of the content}&ctype=flash&swfurl={SWF URI}&height={preferred SWF height}&width={preferred swf width}&screenshot={screenshot URI}

Basically, they are passing variables to an URL including story title, etc. Can Drupal do this out of the box? Is there a mod for this?

Thanks! Any help is greatly appreciated.
