Cohort brief
Auto-generatedThe 288 providers in the APIs.io catalog tagged United States, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Developer Ergonomics | 29.5 | 23.4 | +6.1 | 288 |
| Access Clarity | 31.7 | 26.5 | +5.2 | 288 |

| Contract Quality | 22.4 | 19.8 | +2.6 | 288 |
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.
