Cohort brief
Auto-generatedThe 337 providers in the APIs.io catalog tagged A2A Verified, 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 | 54.2 | 22.1 | +32.1 | 337 |
| Access Clarity | 53.6 | 25 | +28.6 | 337 |

| Discoverability | 74.1 | 57.9 | +16.2 | 337 |
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) | 84% | 16% | +68 |
