Sadly not. One of the constraints of REST is that the API be completely self-descriptive. If you need out-of-band information like an API spec, then it's basically not RESTful by definition.

I'm using a REST API to read your comment and submit my response — I didn't need to reference external HN API docs. The interface here is fully self-describing.

I agree, but don't quite follow how your comment fits in here.

In a REST approach, I'd expect an LLM to need some kind of initial entry point, much like needing the initial URL for the HN home page. From there the LLM should be able to parse and discover possible actions, call those actions, and understand the response only by parsing the results and any schemas provided.

To be honest, I think I meant to put that reply on a different comment.

In any case, we're on the same page about REST. OpenAPI was mentioned though and I don't think that's ever actually compatible with that type of usage.

I don't think I've ever encountered an API following OpenAPI that was completely self describing and could be discovered and navigated from a single entry URL. They're always paired with some swagger docs or other external content. That instantly makes them not RESTful.

But you're totally right that my comment didn't fit. Might have meant it for the grandparent comment? Not sure.
