Sketchfab
Sketchfab is the largest dedicated platform for publishing, sharing, discovering, buying, and embedding interactive 3D content on the web. Founded in Paris in 2012 by Cedric Pinson and Alban Denoyel and acquired by Epic Games on July 21, 2021, Sketchfab hosts millions of 3D models from artists, museums, scanning rigs, and studios — much of it Creative Commons licensed. The platform exposes a public REST Data API for programmatic upload and content management, a JavaScript Viewer API for controlling the embedded WebGL/WebXR viewer, a Download API delivering glTF/GLB/USDZ, an oEmbed endpoint, and OAuth 2.0 authentication, alongside native exporters for every major 3D / DCC tool. Following the Fab.com launch in 2024 the Sketchfab Store has been retired into Epic's unified content marketplace while the publishing, viewing, and developer APIs remain on sketchfab.com.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Sketchfab the way a machine reads it — 32 machine-readable artifacts across 5 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 — Sketchfab scores 69.1/100 (strong), with a separate agent-readiness read of 55/100 (agent ready). 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 Sketchfab
Each block below is one kind of artifact we hold for Sketchfab. 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 5
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.
Individual APIs this provider publishes, each with its own machine-readable definition.
