Cohort brief
Auto-generatedThe 62 providers in the APIs.io catalog tagged JavaScript, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Operational Transparency | 26.7 | 14 | +12.7 | 62 |
| Developer Ergonomics | 33.9 | 23.4 | +10.5 | 62 |
| Discoverability | 64 | 61.2 | +2.8 | 62 |
| Contract Governance | 7.4 | 6.4 | +1 | 62 |
| Access Clarity | 24.6 | 26.5 | -1.9 | 62 |
| Contract Quality | 17.4 | 19.8 | -2.4 | 62 |
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) | 6% | 10% | -4 |
| MCP server (first-party) | 9% | 13% | -4 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 2% | 11% | -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.
