Using GitHub API to retrieve all versions of a specific file

I am currently trying to read through the (GitHub API)[http://developer.github.com/v3/repos/contents/] to figure out how I can programmatically retrieve all versions of a specific file in a single repository.

I see that one can get the list of commits, and the current version of a single file easily. But, is there a way to list all the commits relevant for a specific file and then iterate through all the versions of that file?
