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/.

What adopting Zoho Desk moves on the Kin Score 4

Zoho Desk 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

Zoho Desk gives a provider a declared support channel, 2 points in developer ergonomics, through its Help Center knowledge base or community. Zoho’s own Help Center serves a generated llms.txt, which would be worth 4 points on a provider’s domain, but the same path returned 403 on two customer portals, so treat it as unconfirmed for customers until Zoho documents it. Getting-started and authentication pages count only when the provider writes and declares them.

Across 8977 providers that publish a contract, adopting Zoho Desk would move 3995. Median lift: composite +0.0 (90th percentile +1.0), agent readiness +0.0 (+0.0). Conditional rows excluded.
What Zoho Desk ships that earns nothing (2)
  • Help Center community — A second route to the same binary 2-point check the knowledge base already earns.
  • Help Center domain mapping and multi-brand — No check reads the host of a support pointer.

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.

Customer Support, Helpdesk and Contact Center builds-on 16.3 - -

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.
