Not provided as part of git, as far as I'm aware, but there are other options.

You can probably look at what cgit does to abuse git internals as an API:

It may also make sense to lift code from game of trees:

There's also libgit2:

That seems like a question you'd have to ask yourself. What would you do with it?

For me: I've got a 9p based git file system as part of my implementation of git[1]. It's convenient for scripts on top of git, avoiding scratch files or pipeline wrangling. But on Unix, git already has much of that implemented.

I also tend to open files from old commits or other branches to peek at how some code evolved.
