Cohort brief
Auto-generatedThe 32 providers in the APIs.io catalog tagged JSON:API, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |

| Contract Governance | 11.5 | 6.3 | +5.2 | 32 |
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.
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 31% | 15% | +16 |
