title: On-demand publishing api?
body: <p>Lulu.com is a "self-publishing" service. 
  It appears that they used to have an <a href="http://api.lulu.com/" rel="nofollow noreferrer">api</a>, but it is no longer offered. </p>
  
  <p>I was wondering if there are any similar services in which I could use a scripting language to generate book documents (pdf, xml, whatever), and programatically place individual orders for custom books.</p>
