Given the Universal Turning Machine and the Church-Turing thesis in actuality all of programming except for assembler is pretty much some API or language trick.

Arguably, even machine language is "some API" and assembler "some language trick".

Good point, I forgot for a second that the CPU turns assembler into microcode before executing it.

The CPU often turns machine code into microcode, true, and that's a good point but it wasn't the point I was trying to make. Even in simpler processors that actually do directly execute the machine code, I think you can view that machine code as an API for controlling the processor system.
