Is there a way to automatically generate an address? Alfred integration?

I wanted to try and create a workflow for Alfred (alfredapp.com) or Keyboard Maestro (keyboardmaestro.com)  to generate an email address for domains or apps.  The idea is that you might call the service, pass in the url, and get returned the existing email for the domain, or get a new one generated and returned to you.

Is there an API that would enable this kind of functionality?
