mentioned that "The declaring code is, if copyrightable at all, further than are most computer programs from the core of copyright." This means the code used in APIs are more similar to dictionaries than novels in terms of copyright protection.

What is an API? – in the U.S. Supreme Court opinion, Google v. Oracle 2021, pp. 3–7 – "For each task, there is computer code; API (also known as Application Program Interface) is the method for calling that 'computer code' (instruction – like a recipe – rather than cooking instruction, this is machine instruction) to be carry out" Maury, Innovation and Change – Cory Ondrejka \ February 28, 2014 \ " ...proposed a public API to let computers talk to each other".
