Cohort brief
Auto-generatedThe 25 providers in the APIs.io catalog tagged E-Invoicing, 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 | 45.1 | 23.2 | +21.9 | 25 |
| Contract Quality | 31.8 | 17.6 | +14.2 | 25 |
| Discoverability | 70.8 | 58.1 | +12.7 | 25 |
| Access Clarity | 38.1 | 26.5 | +11.6 | 25 |
| Operational Transparency | 23.4 | 13.7 | +9.7 | 25 |
| Contract Governance | 9.9 | 6.3 | +3.6 | 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 server (any) | 15% | 14% | +1 |
| MCP server (first-party) | 15% | 12% | +3 |

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. 22 of 25 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.
