APIs for SkyWars: Classic and Kits are now available.
For both, statistics are only available for all-time:
/game/all/sky-classic/{player}
/game/all/sky-kits/{player}
Please note XP is shared between SkyWars: Lucky Ores, Classic and Kits.
The addition of the Kits endpoint does not indicate any plans for the return of this mode to the server.
