Markets provisional
Kin Score markets whose measured providers carry this tag. Share is the fraction of the market's measured providers that carry it — it describes the market, not this tag.
| Market | Share of the market's providers |
|---|---|
| Consumer Lending Licensing (UK, US, Canada credit licence registers) | 20% |
| Real Estate and Proptech | 20% |

Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Governance | 8.4 | 9.7 | -1.3 | 143 |
| Access Clarity | 27.5 | 30 | -2.5 | 143 |

| Developer Ergonomics | 19.6 | 24.5 | -4.9 | 143 |
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.

All 154 members of this roster resolve to a provider in the
catalog; 143 carry a score (93%).
The figures above describe the scored members only.
Coverage caveat. 135 of 143 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 14 November 2026, across 41591 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.
