Mojang
Mojang Studios is the developer of Minecraft. The Mojang / Minecraft Services API surface covers Minecraft player identity (UUID and profile lookup), skins and capes, name history and name change, server session verification, blocked server lists, player attributes (privacy, chat, friends settings), friends graph, presence, public keys for profile signature verification, and account entitlements. Endpoints span three hosts: the legacy api.mojang.com, the session-server sessionserver.mojang.com (Yggdrasil), and the modern Microsoft-side api.minecraftservices.com. Most read endpoints are public and unauthenticated; player-account endpoints require a Bearer Minecraft access token obtained via the Xbox Live / XSTS authentication chain.
Mojang publishes 14 APIs on the APIs.io network, including Attributes API, Authentication API, Blocklist API, and 11 more. Tagged areas include Games And Comics, Minecraft, Gaming, Identity, and Player Profiles.
The Mojang catalog on APIs.io includes 4 JSON-LD contexts and 2 Spectral governance rulesets.
Mojang’s developer surface includes authentication, documentation, and 19 more developer resources.
