An example GraphQL query to get `git blame` data from the GitHub GraphQL API

blame.graphql

query {
  repositoryOwner(login: "github") {
    repository(name: "linguist") {
      object(expression: "master") {
        ... on Commit {
          blame(path: "github-linguist.gemspec") {
            ranges {
              startingLine
              endingLine
              age
              commit {
                oid
                author {
                  name
                }
              }
            }
          }
        }
      }
    }
  }
}

@Phalguna2125 Not directly in the query; ranges doesn't support any arguments. But, it does just return an array as opposed to a paginated collection, so clients can just filter by startingLine and endingLine themselves
