Pardon me if I misread, but wouldn't that be better served by a ready-made library (with, if you must AI, some futzing to account for call signature)?

What is the value add of having the AI rebuild code over and over, individually for each project using it?

Author here, the build happens together with building your app. Once built, the code executes deterministically at runtime.

The news here is the AI reading the API docs, assembling requests, and iterating on them until it works as expected.

This sounds simple, but is time consuming and error prone for humans to do.

I don't know, maybe I'm misunderstanding too but they basically just asked an agent to interface with an API. It seems the agent will create new code each time..

I hope this isn't their business model.
