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 |
|---|---|---|---|---|
| Developer Ergonomics | 33.8 | 23.2 | +10.6 | 195 |
| Contract Quality | 26.9 | 17.2 | +9.7 | 195 |
| Discoverability | 63.4 | 57.9 | +5.5 | 195 |

| Contract Governance | 6.7 | 6.5 | +0.2 | 195 |
| Access Clarity | 14.4 | 23.9 | -9.5 | 195 |
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.

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 202 members of this roster resolve to a provider in the
catalog; 195 carry a score (97%).
The figures above describe the scored members only.
Coverage caveat. 182 of 195 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 24 October 2026, across 31984 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.
