KMarket uses vanilla inventory interfaces and is designed primarily as a server-side mod. Players still require any content mods used by the server’s modpack.
Prices, categories, owners, transaction limits, taxes, and other settings can be configured under config/kmarket. Modded items are supported through their registry IDs; unavailable items are safely ignored.
Setup
- Install Fabric Loader for Minecraft 26.1.2.
- Install the matching Fabric API.
- Place
kmarket-1.0.0.jarin the server’smodsfolder. - Start the server once to generate
config/kmarket. - Stop the server before editing the generated configuration.
- Add owner UUIDs to
config/kmarket/owners.json. - Configure prices inside
config/kmarket/prices/. - Restart the server, or use
/kmarket reloadafter changing prices.

"00000000-0000-0000-0000-000000000000"
