Artsy

Artsy (art.sy) is the online marketplace and platform for discovering, buying, and selling fine art, connecting collectors with galleries, museums, art fairs, and auction houses worldwide. Artsy operates a public developer program: the Artsy Public API (v2) is a HAL hypermedia REST API exposing Artsy's database of artists, artworks, genes (the Art Genome Project's classification of artistic characteristics), gallery and museum shows, partners, art fairs, and auction sales. Authentication uses an application-level X-Xapp-Token minted by exchanging a client_id and client_secret. Artsy also runs the Metaphysics GraphQL API that powers its own web and mobile apps. Artsy has announced that the public REST API is being retired and may be taken down without notice; the Partner API remains available to approved partners. Surfaced as a slow-ventures portfolio company and enriched by the API Evangelist pipeline from Artsy's live API and docs.

Artsy publishes 25 API contracts indexed on the APIs.io network, including Applications API, Artists API, Artworks API, and 22 more. Tagged areas include Art, Marketplace, Culture, Museums, and Galleries.

The Artsy catalog on APIs.io includes 1 Spectral governance ruleset.

Artsy’s developer surface includes engineering blog, documentation, API reference, authentication, and 24 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/.

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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

6 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 13.4 — up to +21.7 composite points

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.

Markets this provider is in provisional

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.

Market	Position	Depth	Registered MCP server	Declares compatibility
IIIF and Cultural Heritage (GLAM image interoperability, Linked Art)	undeclared	-	-	-

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 implemented 1

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.
