Ask HN: Tools to make an API from *any* website?

I'm searching for tools that let you automate the extraction of data from any website, which might mean making an API or RSS Feed out of any website. I'm thinking something similar to the old Dapper[1] or Mozenda[2]. Also, what I'm not searching for are scraping libraries and frameworks to use in an application that I would have to develop myself.

What are the tools available?
