Cohort brief
Auto-generatedThe 69 providers in the APIs.io catalog tagged Data Sources, 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 | 56.1 | 17.5 | +38.6 | 69 |
| Developer Ergonomics | 41.2 | 17.9 | +23.3 | 69 |
| Access Clarity | 42 | 22.3 | +19.7 | 69 |
| Operational Transparency | 28 | 11.3 | +16.7 | 69 |
| Contract Governance | 18.1 | 6.4 | +11.7 | 69 |
| Discoverability | 69.7 | 60.4 | +9.3 | 69 |
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) | 35% | 16% | +19 |
| MCP server (first-party) | 16% | 7% | +9 |

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.
