Modpack-related endpoints

• intermediary Intermediary version, generally equal to a given Minecraft version as defined in the game's version manifest.
• yarn Yarn version. Only used if “intermediary” not present; generally, “intermediary” is preferred for production use due to updating once for each given version of the game.
• loader Fabric Loader version.
• format Download format.

• /download/mcupdater - The result is a XML file attachable via an <Import> entry to an MCUpdater ServerPack XML. No custom formats are available.

• /download/multimc - The default result is a ZIP file containing an importable MultiMC instance. Alternate formats:
  • patchJson Returns a JSON representing a MultiMC patch for Fabric.

• /download/vanilla - The default result is a ZIP containing a Fabric game profile, which can be extracted to .minecraft/versions. Alternate formats:
  • profileJson Returns a JSON representing a vanilla Fabric profile.
  • shimJar Returns a JAR containing a single file, version.json, with the vanilla Fabric profile. This is intended for future SKCraft/Solder support.

The Maven metadata XML files can be used to query the latest and available versions of Fabric components.

• Fabric Loader: https://maven.fabricmc.net/net/fabricmc/fabric-loader/maven-metadata.xml
• Yarn: https://maven.fabricmc.net/net/fabricmc/yarn/maven-metadata.xml

A HTTP JSON API is provided to allow lookup of Fabric versions for a specific Minecraft version, among other things. See the documentation on the Github, the API service is hosted at https://meta.fabricmc.net/ .

If you find something missing from the meta service open an issue on Github for it to be evaluated.
