Plugin for static code analysis pull request (Server API)

[Andrey Budaev]

I'm attempting to automate the static code analysis for created pull requests. Is there a way of getting diff on a specific file in the pull request via Server API? 

Like this REST API request:

"http://bitbucket.com/rest/api/1.0/projects/PROJ/repos/CODE/pull-requests/1/diff/path/to/file/AssemblyInfo.cs"
