Is there a Web Service API to the Google Product Search?

Question

I want to call the Google product search and get back a parse-able XML file rather than having to scrape the HTML. I'm not looking for a SOAP based service, but a service that returns XML based on a URL passed in.

Correction--this did NOT work:

The Google Base API lists only a subset of Google product sellers (apparently only those who are active users of the Google Base product.) http://code.google.com/apis/base/docs/2.0/attrs-queries.html

I eventually ended up using a screen scraping solution and then found that the data was too inconsistant to use for my purposes at all. :-(
