Roblox
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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Roblox the way a machine reads it — 14 machine-readable artifacts across 8 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Roblox scores 31.7/100 (thin), with a separate agent-readiness read of 16/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Roblox
Each block below is one kind of artifact we hold for Roblox. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 8
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

GraphQL 1
Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.

GRAPHQLPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.

PLANSRate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
