Helping me get up to speed with an unfamiliar API much, much faster than any online searching.

I can describe an example application and see which API is chosen, along with which functions/methods are called and in what order and with what data structures.

I take it from there and build on that by hand. Take Python UI development, for example. I can ask for a window with a zoomable bitmap image with scrollbars. I get an answer I can refer to in seconds. If I know that I want PySide6 or PyQt6, I can specify that, or I can ask for a list of Python UI APIs and their strengths/weaknesses.
