RealAPI

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): RealAPI did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/networking/v1/PayloadTypeRegistry; RealAPIClient did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/client/rendering/v1/ClientTooltipComponentCallback.

In the author's words

This mod has alot of code I think would be nice to develop with!

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file realapi-0.4.100.jar. The scan reads the mod's classes; it does not run them.
