Top mods / Caelus API
Not listed
Caelus API doesn't list Minecraft 26.3 on Modrinth. The newest release it lists is 1.21.5, on NeoForge.
This is what the mod's author listed on Modrinth, not a test. A listing doesn't prove a mod runs on your setup, and a missing listing doesn't prove it fails. Versions must match exactly, and files published elsewhere, such as CurseForge, aren't counted.
