"APIs are not code" - most APIs are literally part of the code.

"The decision to have a function called `sqrt` and put it in a module called `math` is not creative, and it is definitely not artistic."

Yes, it absolutely is, in the sense that literally any arbitrary sentence or gibberish that I write is creative and copyrightable.

I can copyright: "Blahdy Blady Blady Blah" right now.

API design is as creative as any other part of the code.

You can’t copyright that - precisely because it is not a significant creative work.

The question is an API a significantly creative work, vs the implementation.

Historically - because the entire modern world depends on it - APIs were not considered copyrightable, largely because the creativity is embodied by the implementation.

You clearly disagree, I am curious if you believe being able to have competing software was detrimental - for example say MS claimed copyright over the XMLHttpRequest API? Or google over search engine query API, etc

And colors are part of a painting. Do you believe that colors are copyrightable?

Letters are part of a novel, do you think that authors have a copyright to the letters that they use?
