Frequently asked

How do I install Isekai API?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Isekai API safely?

Start with the author's page on CurseForge, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.

Which Minecraft versions does Isekai API work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old mod with no declared version as untested on modern Minecraft.

Details from CurseForge, where the author last updated it on 4 Sept 2026. We do not host files and we do not republish descriptions; every download link points at the author’s own release.

Not indexed yet. Score 48 against a threshold of 55. The page still exists and is still linked; it simply carries noindex until we hold more.
