I was looking at the Unoffical API documentation for Stack Overflow on Meta Stack Overflow and I couldn't find a search API. I was working on a code search like utility and would like to utilize results from Stack Overflow and link the results back to Stack Overflow. I can use the OpenSearch API on this URL - stackoverflow.com/search?q={searchTerms} and get to Stack Overflow, but I was wondering: is there an API where I can get XML results and I can link the results back to Stack Overflow?
I know the data for Stack Overflow is available under Creative Commons, but parsing, indexing, keeping it up to date seems sort of an overkill. A JSON/XML based API would be great.
