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.

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.

In my experience, most "SDK" we have today is just thin wrapper of the HTTP call generated from openapi / swagger.

It take lots of readings and testing before integrating to your project.
