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.
Sketchfab publishes 14 API contracts indexed on the APIs.io network, including Download API, Bookmarks API, Categories API, and 11 more. Tagged areas include 3D, Models, Marketplace, Viewer, and WebGL.
The Sketchfab catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Sketchfab’s developer surface includes authentication, developer portal, documentation, getting-started guide, signup flow, pricing, engineering blog, and 50 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Show this score on your site.
It updates itself when the score changes. Paste this where you link to your API docs:
<a href="https://apis.io/providers/sketchfab/"><img src="https://apis.io/badge/sketchfab/card.svg" alt="Sketchfab on APIs.io — Kin Score by API Evangelist"></a>

Agent readiness — checks not met, largest first (exact, from this profile):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
