I think that creates an API, then exposes it in numerous languages. This writes wrappers to existing APIs. Not the same thing. (Lots of code similarity under the hood, though.)

No, it actually does both - which is why I was so interested in it initially.

from the above link: "generates code to be used to easily build RPC clients and servers"

TBF, I haven't used it as a developer, but I did contract work with a company that had invested in it heavily. From what I saw of their workflow, it ended up being a pretty nice bootstrap tool and little more.

edit: Oh, I see what you're saying. Yes, you're correct - thrift does not wrap existing APIs.
