I'd like to add new pages by sending an HTTP request to an endpoint. I saw it mentioned in issues such as #339 and items linked in that thread.

There seemed to be commit names that mentioned adding a REST API, but I haven't been able to find whether those are already implemented and released.

Are they? If so, how do I call them?

I've tried just capturing a request to the "Add" method when I click it in the browser, but it looks like there is some csrf protection, so I can't just copy-paste some bearer token and re-issue requests. I'm asking here before I spend time reverse-engineering something just because I missed an already existing API. :)
