Markets provisional
Kin Score markets whose measured providers carry this tag. Share is the fraction of the market's measured providers that carry it — it describes the market, not this tag.

Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Discoverability | 64.5 | 59.1 | +5.4 | 217 |
| Operational Transparency | 8.6 | 13.2 | -4.6 | 217 |
| Contract Governance | 2.9 | 9.7 | -6.8 | 217 |

| Contract Quality | 7.1 | 18.6 | -11.5 | 217 |
| Access Clarity | 11.6 | 30 | -18.4 | 217 |
A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
What this cohort publishes
| Artifact | This cohort | Catalog | Difference |

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.

All 219 members of this roster resolve to a provider in the
catalog; 217 carry a score (99%).
The figures above describe the scored members only.
Coverage caveat. 201 of 217 scored members had under half their catalog-attributable points satisfied at all (catalog_earned / catalog_max < 0.5). They are INCLUDED in the mean above. A large share here means the cohort mean is partly a measurement of how far our enrichment reached, not only of how these providers publish.Generated from the catalog build of 14 November 2026, across 41591 providers, using the same computation served by the APIs.io cohort API. Briefs are published for rosters of 5 or more scored providers; below that a distribution is not meaningful.
