API recorder broken on several demos

[pngwn]

Describe the bug

The API recorder seems to work in simple cases but there are quite a few demos where it doesn't work.

Most notably it doesn't work with the ChatInterface.

Do almost anything and record the requests, and it will break.

What isn't clear to me is how we are supposed to handle the API recorder if certain API requests are essentially 'hidden' from the client. What is more, we don't return info for unnamed routes from /info, so I'm not sure how we are supposed to get hold of this information. We somehow need to workaround these constraints for the API recorder to work.

In terms of what is happening. I'm pretty sure the API recorder works fine but we don't have the information required to build the queries correctly due to the various client changes + how the information to make those changes only applies to certain routes.
