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 →
Strong 2 Solid coverage with minor gaps
Developing 2 Usable, with meaningful gaps to close

Companies reaching this through an API (8)
These companies publish an API, specification or operation carrying “Cross-Chain” 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 35 providers in the APIs.io catalog tagged Cross-Chain, 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 | 45.6 | 23.2 | +22.4 | 35 |
| Contract Quality | 28.5 | 17.6 | +10.9 | 35 |
| Operational Transparency | 22 | 13.7 | +8.3 | 35 |
| Discoverability | 65.1 | 58.1 | +7 | 35 |
| Contract Governance | 6.3 | 6.3 | 0 | 35 |
| Access Clarity | 21.6 | 26.5 | -4.9 | 35 |
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) | 37% | 14% | +23 |
| MCP server (first-party) | 37% | 12% | +25 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 0% | 11% | -11 |
| Security | 100% | 98% | +2 |
| Arazzo workflows | 6% | 2% | +4 |
| Governance rules | 17% | 14% | +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. 28 of 35 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.
