How to get blame information of a line of code on a repository from github API

Question

I searched through all the existing github API s found in here to get blame information of a certain line of code in a source file, but I couldn't find a way to achieve it, such API is not listed in the above site. Can anyone point me a way to get the blame information of a line of code of a source file, which is hosted in github repos without cloning it and running git blame locally.

Thanks in advance

The GitHub API v4 has a working blame API. Here's an example of the proper query:

{
  # repository name/owner
  repository(name: "MidiPlayerJS", owner: "TimMensch") {
    # branch name
    ref(qualifiedName:"tim") {      
      target {
        # cast Target to a Commit
        ... on Commit {
          # full repo-relative path to blame file
          blame(path:"package.json") {
            ranges {
              commit {
                author {
                  name
                }
              }
              startingLine
              endingLine
              age
            }
          }
        }
      }
    }
  }
}

This works in the explorer for me.

There's no Blame API in the GitHub REST API http://developer.github.com/v3/

But you can fetch blame information through the new GraphQL API which is in early access mode. see this doc https://developer.github.com/early-access/graphql/
