Official SDKs on Package Registries
Distribution market (official client libraries per language; providers ranked). The Kin Score Market layer reads each provider in its market: who it integrates with, how deep those integrations go, and where the market publishes its own structure. Methodology.
43providers measured
31 (72.1%)declare their own
3 (7.0%)covered by others only
9 (20.9%)distribution only (sell through, not integrations)
0 (0.0%)undeclared
4declare compatibility (report only, not weighted)
15in-market workflows shown
Provisional. Provisional and unweighted: the Market layer is not part of the composite or agent readiness. Leader lists are read within a position, never as one ranking. A provider that declares nothing we can
read is shown as undeclared, with no number: we never infer integrations.
Where this market publishes its structure
- npm registry (registry.npmjs.org/
/latest + abbreviated doc) machine-readable, 8,543 candidates; 2,991 linked packages / 1,238 providers; 4,594 held; 142 not on registry; 6 unreadable - PyPI JSON (pypi.org/pypi/
/json) machine-readable, 2,845 candidates; 693 linked / 523 providers; 2,108 held; 45 missing; 2 unreadable; PyPI JSON exposes no organisation, publisher = author/maintainer e-mail - Go module proxy (proxy.golang.org/
/@latest) machine-readable, 920 candidates; 566 linked / 386 providers; 309 held; 38 missing; 19 unreadable (proxy errors / invalid module paths) - Maven Central (repo1.maven.org maven-metadata.xml + POM) machine-readable, 1,158 candidates; 447 linked / 226 providers; 580 held; 96 missing; 56 unreadable (POM / metadata fetch failures)
- NuGet (api.nuget.org registration + azuresearch owners) machine-readable, 627 candidates; 138 linked / 89 providers; 487 held; 14 missing; 7 unreadable
- RubyGems (rubygems.org/api/v1 gems + owners) machine-readable, 599 candidates; 128 linked / 102 providers; 478 held; 7 missing
- crates.io (crates.io/api/v1 crates + owners) machine-readable, 402 candidates; 45 linked / 26 providers; 351 held; 8 missing; paced 1 req/s per crates.io policy
- Packagist / CocoaPods / pub.dev / Hex not machine-readable: not swept this pass: the catalog's packages files carry too few entries for these registries to verify (2026-10-19)
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
Taxonomy how this market maps onto apis.io
Derived 2026-10-19 from the 43 providers in this market we could resolve in the catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.

Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside position, never inside it. Unknown-builder listings are left out of position shares and counted here.

Top workflows by market votes
Workflows (Arazzo) and their phrasing are generated by API Evangelist, ranked by market votes (integration edges in the graph, weighted by channel).
In-market workflows only: a step on the market provider's side maps to this market's business capabilities (), and the partner is not a generic export/notify app. Other workflows are counted as bridges (including any whose steps do not resolve to a capability yet). Methodology. In-market: 72; bridges: 0.
