Cohort brief
Auto-generatedThe 67 providers in the APIs.io catalog tagged Metadata, 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 | 43 | 19.8 | +23.2 | 67 |
| Operational Transparency | 29.4 | 13.9 | +15.5 | 67 |
| Access Clarity | 40.1 | 26.5 | +13.6 | 67 |
| Developer Ergonomics | 35.4 | 23.4 | +12 | 67 |
| Discoverability | 69.8 | 61.2 | +8.6 | 67 |
| Contract Governance | 13.4 | 6.4 | +7 | 67 |
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) | 10% | 10% | 0 |

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.
