API and Module the same?

Question

I know there are completely different things, but aren’t they conceptually the same in some ways?

You basically using API or Module to build something on top of whatever you are building, right?

Answer 1

Module is a set of functions. API is an interface to those functions. Home and door.

Answer 2

The term "module" is very ambiguous and relies heavily on context to determine its specific meaning.

If there's confusion about what an API is, the simplest way I've found to think of it is something like:

Web Application = UI + API

where web applications require some kind of front end / UI (no matter how basic) so users can access and interact with it and some kind of back end ("web service") so the front end has some way to interact with the server(s) (send/receive messages).
