Is there anything close to having a relatively automated solution to

look pretty, just work.

It's nowhere as plug-and-play as what you've envisioned, sadly, but perhaps you could have some success by having your endpoints output a [Siren] hypermedia representation of your server resources and then pointing one of the various API browsers[1][2][3] at it, though they do look like development has been abandoned nowdays, sadly.

I even have some (very old, never published, never battle-tested, unmaintained, probably broken, not so well designed) [code] that's handy to generate Siren resource representations; it may serve as a starting point if you decide this is a reasonable way forward.
