**APIs profiled:** 8

Roblox is a user-generated content platform where creators build, publish, and monetize immersive 3D experiences using Roblox Studio and the Luau scripting language. Roblox exposes three distinct developer surfaces: the in-engine Luau scripting API (Roblox Engine API) running inside experiences and Studio plugins, the Roblox Studio plugin API for editor tooling, and the Open Cloud API (apis.roblox.com) for external programmatic access from servers, build pipelines, and back-office tools. The Open Cloud surface covers DataStores, Memory Stores, Messaging Service, Place Publishing, Universes, Assets, Inventory, Users, Groups, Notifications, Subscriptions, and Luau Execution, authenticated either with API keys scoped per-resource or with OAuth 2.0 for third-party apps. Roblox also publishes deep documentation for the Engine API at create.roblox.com/docs and the legacy ROBLOX Web APIs that power the website (subdomains such as users.roblox.com, groups.roblox.com, inventory.roblox.com), which remain undocumented for third parties.
