Emerging 10 Early or largely undocumented
Minimal 1 Almost no public developer surface
APIs with this tag (14)
Ranked by the provider's API Evangelist rating — the Kin Score is scored per provider, not per API, so every API of a provider shares its band. How the rating works →

Companies reaching this through an API (4)
These companies publish an API, specification or operation carrying “CNCF” but do not classify their business under it. Listed unranked and kept out of the count above, because one tagged operation is not a statement about what a company does.

Cohort brief
Auto-generatedThe 47 providers in the APIs.io catalog tagged CNCF, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Quality | 37.3 | 17.6 | +19.7 | 47 |
| Operational Transparency | 32.8 | 13.7 | +19.1 | 47 |
| Developer Ergonomics | 36.8 | 23.2 | +13.6 | 47 |
| Contract Governance | 18.8 | 6.3 | +12.5 | 47 |
| Discoverability | 60.5 | 58.1 | +2.4 | 47 |
| Access Clarity | 15.1 | 26.5 | -11.4 | 47 |
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) | 4% | 14% | -10 |
| MCP server (first-party) | 2% | 12% | -10 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 2% | 11% | -9 |
| Security | 94% | 98% | -4 |
| Arazzo workflows | 2% | 2% | 0 |

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.
