Google made the following announcement with respect to the Google Search API for Shopping:
We’re deprecating our Search API for Shopping, which has enabled developers to create shopping apps based on Google’s Product Search data. While we believe in the value this offering provided, we’re shifting our focus to concentrate on creating a better shopping experience for users through Google Shopping.
