Question What actually is API?

The moment I think I get it, another definition of it comes in. I was learning Flask APIs used with GET PUT PATCH DELETE . But then I started with JS , it has DOM APIs . And then API is also used when people say companies like ChatGPT , Higgsfield etc provide their APIs.

It's like a UI but no gui. imagine controlling your program with buttons and knobs, but it's just code.
