Rail by region (4)
Each region is a page of its own, holding only the rail providers headquartered there. Greyed pills are below the 5-provider floor — published as a roster, without generated statistics.
Rail by country (4)
Country membership is matched on an exact country tag only — no headquarters signal — so these cells understate by construction and read lower than the region cuts above.

Cohort brief
Auto-generatedThe 25 providers in the APIs.io catalog classified under Rail, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Governance | 9.1 | 6.3 | +2.8 | 25 |
| Discoverability | 62.8 | 61 | +1.8 | 25 |
| Contract Quality | 16.2 | 19.8 | -3.6 | 25 |
| Developer Ergonomics | 19.6 | 23.3 | -3.7 | 25 |
| Operational Transparency | 9.6 | 13.9 | -4.3 | 25 |
| Access Clarity | 18.2 | 26.3 | -8.1 | 25 |
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_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.
