Cohort brief
Auto-generatedThe 189 providers in the APIs.io catalog tagged APIKeys, 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 | 57.8 | 17.5 | +40.3 | 189 |
| Developer Ergonomics | 49.3 | 17.9 | +31.4 | 189 |

| Discoverability | 74.7 | 60.4 | +14.3 | 189 |
| Contract Governance | 17.9 | 6.4 | +11.5 | 189 |
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.
