GitHub API: How to get branch name from commit list?

Let's say I've got the following commits in my master branch.

a <- b <- c <- d <- e

Then I create another branch called feature. I make a single commit on this branch. It looks like this.

                      <- f
a <- b <- c <- d <- e

When using the list commits api I can get all commits for my feature branch. Is there a way to see from the result that my commit f is on the feature branch and the rest is in master?

Or do I have to make another request to the compare two commits api? In the end I'd like to have all commits (a - f) with the branch they belong to.

Edit: m stands for master and f for feature.

branch: m <- m <- m <- m <- m <- f
commit: a <- b <- c <- d <- e <- f

(You already discovered the compare API; I include it below because it seems weird that they use another syntax.)

Commits A through E are in branch feature.

This is a big surprise to those used to other version control systems in which a commit is in exactly one branch. In Git, commits are in zero or more branches.

To list commits that are in feature but are not in master, you tell Git: Collect a set of all commits in feature. Collect a second set of all commits in master. Subtract the second set away from the first set, and show me the resulting set.

The command-line syntax for this is master..feature or feature ^master. Note that there are two, not three, dots between the two names. The three-dot syntax exists as well, with a different meaning (symmetric difference—which is a superset of the two-dot meaning, but requires left side / right side indicators to be used to obtain the two-dot meaning).

The GitHub API page suggests a REST API that may be equivalent. Curiously, the REST API uses the three-dot syntax, but the description says it produces the same result as the two-dot syntax. Whether it does, I do not know.
