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)
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
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

8 more unmet checks in the Agent Readiness table above.

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

Help Scout 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.

supportcapability map4 features checked 2026-09-25 · rubric v0.22.0

Help Scout Docs gives a provider one check on its own: a declared Docs site is a support channel, 2 points in developer ergonomics. Docs can also host a getting-started guide and an authentication page, and some providers do run their developer help there, but only the provider writing and declaring those pages moves those checks. Help Scout’s MCP server (mcp.helpscout.net) is a read-only connector for the provider’s own support team and earns nothing. No community forum and no llms.txt on Help Scout’s own Docs site.

Developer Ergonomics12.0 of 42 pts

Check	Earns	Through
Authentication documentedsaturated Developer ErgonomicsOnly if the provider documents its API authentication in a Docs article and declares it as Authentication.	5.0 of 5	Docs knowledge base
Support channel Developer ErgonomicsDeclare the Docs site in apis.yml common[] as HelpCenter or Support. If the provider declares it as Documentation instead, it earns documentation_present and not this check.	2.0 of 2	Docs knowledge base
Getting started guideconditional Developer ErgonomicsOnly if the provider writes a getting-started guide for its API as a Docs article and declares it as GettingStarted.	5.0 of 5	Docs knowledge base

Across 8977 providers that publish a contract, adopting Help Scout would move 3995. Median lift: composite +0.0 (90th percentile +1.0), agent readiness +0.0 (+0.0). Conditional rows excluded.

What Help Scout ships that earns nothing (3)

Docs custom domain — No check reads which host a support pointer lives on.
Beacon — An embedded widget is not a pointer; the Docs site behind it is what gets declared, and it earns the check once.
Help Scout MCP server — A staff-facing connector to the provider’s helpdesk on a Help Scout host is not an MCP server for the provider’s API.

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
Customer Support, Helpdesk and Contact Center	covered	36.9	-	-

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 2

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.
