Since the Google API is no more, perhaps you could try another search engine?
DuckDuckGo's API might help, but might not ...
Our Instant Answer API gives you free access to many of our instant
answers like: topic summaries, categories,
disambiguation, and !bang redirects.
This API does not include all of our links, however.
That is, it is not a full search results API or a way to get DuckDuckGo results into your
applications beyond our instant answers.
Because of the way we
generate our search results, we unfortunately do not have the rights
to fully syndicate our results. For the same reason, we cannot allow
framing our results without our branding.
The Bing API looks more promising
Bring intelligent search to your apps and harness the ability to comb billions of webpages, images, videos, and news with a single API call.
BUT, see the pricing and decide if are you willing to pay.
What about Yahoo! (as was; what will happen now that it has been bought out?)
we will discontinue the BOSS JSON Search API on March 31, 2016.
Check out other search engines?
Or search for other APIs which might be useful? For instance on Programmable Web, which has thousands.
