Regalia Slots API

A flexible, expandable accessory and equipment-slot API for Minecraft, ported and rebranded from Curios API.

Most mods that add a necklace, a ring or a pair of wings need somewhere to put them. This is that place — a slot system that both developers and players can shape, rather than a fixed set of hardcoded slots.

It adds no gameplay content. What it contributes is an inventory GUI and a handful of example items in the creative menu. Everything else is API surface for other mods to build on.

What makes it different from just using Curios

Slots are made on demand. There are no empty accessory slots baked in. A slot appears because a mod declared it and something wants to go in it — so you do not end up staring at a row of holes waiting for the right item.

Identical identifiers merge. If two mods both register a ring slot, they get one slot, not two competing ones. Unique identifiers are still available to mark genuinely special cases.

Players can reshape it. Slots can be disabled, hidden, resized, reordered or given custom backgrounds — and the whole set can be reduced to none, if you would rather mods add slots entirely on request.

It speaks Curios. Mods built against the real Curios API are recognised and interoperate without Curios installed. See Curios Compatibility.
