Cohort brief
Auto-generatedThe 68 providers in the APIs.io catalog tagged Metadata, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Quality | 41 | 17.6 | +23.4 | 68 |

| Contract Governance | 13.1 | 6.3 | +6.8 | 68 |
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 server (any) | 13% | 14% | -1 |
