The Yahoo Shopping team, to its credit, posted the news to developers with plenty of notice:
- After careful consideration, we have decided to enter into a strategic partnership with PriceGrabber to power the Product Submit functionality of Yahoo! Shopping as of March 11, 2010. As a result of these changes, Yahoo! will no longer provide the Shopping Web Services API, including Shopping Results (the “Yahoo! Shopping Syndication Services”) to you as of March 11, 2010.
There is no way to even browse the API methods available to developers without contacting the PriceGrabber business development team. And, without a price listing, developers are left assuming the service is out of their price range. We have an email into the PriceGrabber team and will update if we hear back.
