Cohort brief
Auto-generatedThe 559 providers in the APIs.io catalog tagged Fortune 500, 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 | 4.8 | 6.4 | -1.6 | 559 |
| Contract Quality | 10.6 | 17.5 | -6.9 | 559 |
| Operational Transparency | 4 | 11.3 | -7.3 | 559 |
| Discoverability | 51.8 | 60.4 | -8.6 | 559 |
| Developer Ergonomics | 6.1 | 17.9 | -11.8 | 559 |
| Access Clarity | 8.2 | 22.3 | -14.1 | 559 |
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) | 1% | 16% | -15 |
| MCP server (first-party) | 0% | 7% | -7 |
