A paid whitelist for a private Minecraft server. Players sign in with Discord, buy a permanent spot, set their in-game name – and the server itself asks this app who is allowed in.
The part I like most is the whitelist endpoint: the Minecraft server calls it with the player's username and a secret header, gets a yes/no back, and the game's whitelist is never edited by hand.
