Cohort brief
Auto-generatedThe 26 providers in the APIs.io catalog tagged Layer 1, 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 | 50.3 | 23.4 | +26.9 | 26 |
| Operational Transparency | 25.9 | 14 | +11.9 | 26 |

| Contract Quality | 29 | 20.1 | +8.9 | 26 |
| Contract Governance | 5.8 | 6.5 | -0.7 | 26 |
| Access Clarity | 17.4 | 26.5 | -9.1 | 26 |
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) | 27% | 10% | +17 |
| MCP server (first-party) | 31% | 13% | +18 |

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
