Yes, forgified fabric api is required

It has the same modid for compat reasons https://www.curseforge.com/minecraft/mc-mods/forgified-fabric-api

bruh then it isnt really a neoforge mod :/

I use ffapi to avoid duplicating network code, it is a NeoForge mod, it uses a pre-processor to allow me to generate two jars from one source set. One for NeoForge and one for Fabric.
