Official SDKs on JSR (JavaScript Registry)
Distribution market (official javascript / typescript client libraries on jsr; 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.
Where this market publishes its structure
- JSR package index (jsr.io/api/packages?limit=100&page=N) machine-readable, 20,887 packages over 209 pages (API reports total 22,798; paging stops at page 210 with an empty page -- the remainder is not served by the listing); 22 linked packages / 19 providers
- JSR scope metadata + scope package lists (jsr.io/api/scopes/
, /api/scopes/ /packages) machine-readable, read for each linked scope; scope metadata carries no homepage / owner domain; the bare /api/scopes path 404s - JSR package versions (jsr.io/api/scopes/
/packages//versions) machine-readable, release date of the latest version, linked packages only - JSR scope members (jsr.io/api/scopes/
/members) not machine-readable: public, but lists individual people; not read (PII guardrail)
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 2026-10-23 from the 19 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.

Leaders by position (provisional)
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.
