Cohort brief
Auto-generatedThe 51 providers in the APIs.io catalog tagged Reference Data, 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 | 51 |
| Operational Transparency | 32.3 | 14 | +18.3 | 51 |
| Access Clarity | 42.6 | 26.5 | +16.1 | 51 |
| Contract Quality | 34.9 | 19.8 | +15.1 | 51 |
| Discoverability | 72.4 | 61.2 | +11.2 | 51 |
| Contract Governance | 13 | 6.4 | +6.6 | 51 |
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) | 22% | 10% | +12 |
| MCP server (first-party) | 22% | 13% | +9 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 27% | 11% | +16 |
| Security | 100% | 97% | +3 |
| Arazzo workflows | 2% | 2% | 0 |
| Governance rules | 20% | 14% | +6 |
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.
