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 | 49.1 | 23.2 | +25.9 | 26 |
| Operational Transparency | 25.2 | 13.7 | +11.5 | 26 |
| Discoverability | 67.5 | 58.1 | +9.4 | 26 |
| Contract Quality | 25.1 | 17.6 | +7.5 | 26 |
| Contract Governance | 5.5 | 6.3 | -0.8 | 26 |
| Access Clarity | 16.9 | 26.5 | -9.6 | 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) | 31% | 14% | +17 |
| MCP server (first-party) | 27% | 12% | +15 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 8% | 11% | -3 |
| Security | 100% | 98% | +2 |
| Arazzo workflows | 0% | 2% | -2 |
| Governance rules | 12% | 14% | -2 |
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.

Coverage caveat. 23 of 26 scored members had under half their catalog-attributable points satisfied at all (catalog_earned / catalog_max < 0.5). They are INCLUDED in the mean above. A large share here means the cohort mean is partly a measurement of how far our enrichment reached, not only of how these providers publish.Generated from the catalog build of 5 October 2026, across 29093 providers, using the same computation served by the APIs.io cohort API. Briefs are published for rosters of 5 or more scored providers; below that a distribution is not meaningful.
