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
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
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)

10 more unmet checks in the Agent Readiness table above.

Keycloak is an area vendor: providers adopt it to run part of their developer surface. This is the Kin Score checks its features can move for a provider that adopts it, what each one really earns, and what it earns nothing for.

identitycapability map5 features checked 2026-09-25 · rubric v0.22.0

Keycloak is self-hosted, so its discovery document already sits on the provider’s own domain, and it advertises authorization_code and a registration endpoint. But the document lives under the realm path, and the harvest probes only the host root, so the served tiers of auth clarity, delegated identity and dynamic client registration are reached only if the provider also answers the root well-known paths (a reverse-proxy rewrite). Keycloak says outright that protected-resource metadata is the MCP server’s job, and it does not yet support RFC 8707 resource indicators.

Across 8977 providers that publish a contract, adopting Keycloak would move 8268. Median lift: composite +2.4 (90th percentile +2.7), agent readiness +5.0 (+5.9). Conditional rows excluded.

What Keycloak ships that earns nothing (2)

Certified specifications incl. FAPI — The OpenID/FAPI certifications are Keycloak’s; the check reads a certification the provider holds.
Realm-scoped OIDC discovery — openid-configuration is not one of the well-known documents that check reads, at any path.

A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership can. The rating is not for sale → · Full vendor facets artifact

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
Identity and Auth	standard	48.4	-	-
OpenID Certified Implementations (OIDC, FAPI, OpenID4VC)	standard	48.4	-	-
OpenSSF Best Practices Badge Holders	standard	48.4	-	-

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 5

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.
