Creo API
by creoii
Creo API is a Fabric library for modders and datapack creators, providing shared utilities and extra worldgen tools so they can build on one common base.
What it does
The library offers a set of helpers for editing vanilla blocks, items and entity types, and an expanded version of block and item settings that makes common changes easier to write. It adds more than 50 new tags covering blocks, items, entity types, enchantments and biomes, so datapacks and mods can reference them directly.
For world generation, Creo API supplies extra feature and structure placement tools, density functions, placers and surface rules, along with a FastNoise implementation. Its modules can be loaded separately, so a project can include only the parts it uses and keep the file size small. The author describes it as a higher-layer addition on top of Fabric API, aimed at both modders and datapack developers.
Every player and the server need a copy of the mod. Builds exist for Fabric only, across seven release versions 1.19.4 – 1.21.1, with 0.7.9+1.20.6 for 1.20.6 as the latest file. It is not open source; the code is under All rights reserved. The project is archived, though the author has said it may return in the future. Wilder World requires it.

What the author says
This API has been archived and will not be updated. I may come back to it in the future, though. Creo API targets both modders & datapack creators, aiming to provide both with useful features.
