Lifehacker.com - Turns Web Sites into PDF Files Online

An API would be rad. I've used HTMLDoc (http://www.htmldoc.org/) by sending URLs to the command line for projects before, but they don't render the same and require special instructions inserted into the HTML for some formatting options.

A site with a simple API to send a URL and receive a PDF link back, maybe a handful of options, and a reasonable cost per request would also eliminate the setup of extra tools on customer sites, which sometimes aren't available due to them choosing shared hosts.

This could be an useful tool for snapshots.
