Looking for this that already integrates with e.g. mkdocs...

In particular, the narrowest use case we want is simply exercising REST APIs (and GraphQL APIs) with changed up params, something like a baby embedded Postman.

Expanding that to single boxes of a notebook or tiny Python runners like this (or as are used in Code Interpreter in ChatGPT) is even better.

Anyone already have or working on these?

(For our use case, assume the user is browsing the docs with an SSO account and all hosts, code, and data, under the hood supports the identity.)
