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/.

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. This rating is computed from github.com/api-evangelist/postman: open an issue to ask a question, or submit a pull request to add artifacts.

Postman 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.

api collectionscapability map13 features checked 2026-09-25 · rubric v0.22.0

Postman moves a provider’s score through the files it helps the provider publish, not through the Postman brand. A collection in the provider’s own public workspace earns postman_present at full credit; one a community member or a vendor forked or generated does not. Collection-published docs, a public mock server, and Spec Hub’s OpenAPI generation can each earn a pointer or contract check once the provider declares them, but a generated spec inherits whatever the collection was missing. The MCP Generator produces code the provider must deploy itself, which grades as a template, and the Postman MCP server, agent skills and API Network listing describe Postman, not the provider’s API.

Check	Earns	Through
MCP Servertemplated Agent ReadinessThe generator emits one template per request for the provider to run and host; it is not a probed remote server on the provider’s domain. At best `templated` (0.6) once deployed and declared; left as a local download it reaches nothing.	7.2 of 12	MCP Generator

Across 8977 providers that publish a contract, adopting Postman would move 8968. Median lift: composite +5.7 (90th percentile +7.3), agent readiness +5.2 (+6.5). Conditional rows excluded.

What Postman ships that earns nothing (5)

Run in Postman button — It forks the collection into the consumer’s own client; nothing is hosted to try against, so it is not a console. It helps a reader reach the collection that postman_present already credits.
Postman MCP Server — mcp.postman.com exposes Postman’s platform API, not the provider’s; the dimension reads the provider’s own mcp/ manifest.
Agent skills installed by the Postman CLI — The skills teach an agent to drive Postman and its CLI; they are Postman’s, not a skill for the provider’s API.
API governance rules and API Catalog — The rules are enforced inside Postman workspaces; the check reads a ruleset the provider publishes. Nothing on the governance page publishes the rules outside Postman.
Postman API Network listing and verified publisher badge — A directory listing on postman.com is a catalog entry on a host the provider does not control, which is what this check discounts.

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
Developer Tools	builds-on	28.9	1	-
AI Agent Tools (MCP servers, A2A agents)	builds-on	28.9	1	-
AI Agents (A2A agent cards)	builds-on	28.9	1	-

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 8

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.
