Can you list the raw materials required to build a MyProductionItem?

I'm hoping there is a way accessible through the API to get this. For example, making a steel plate requires 7 iron. I've started to hardcode each item, which isn't too bad since there's only 26, but if anything changed during a future update I'd have to also update my script, also there's the fact that (while sort of rare) some mods add new components to the game, which I have no knowledge of, so I'm also losing mod support.

Here's the script I'm working on, you can see in the bottom...
