US NPI Health Provider Registry (CMS NPPES)
Regulated register market (cms nppes npi-2 enumeration, nppes endpoints, cms national directory). 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
- CMS NPPES NPI Registry API v2.1 (npiregistry.cms.hhs.gov/api, NPI-2 organisations) machine-readable, 1,127 health-tagged candidates looked up by catalog name; 140 exact legal-name hits; 22 linked (2 by own-domain endpoint, 20 by name + Wikidata HQ state); 2 held on hand review
- NPPES endpoint field on the matched records (Direct / FHIR / CONNECT) machine-readable, own-domain endpoints on 2 linked providers (Alto Pharmacy Direct, Athelas); 1 platform endpoint-coverage edge (ABILITY Network hosts Mayo Clinic's esMD CONNECT endpoint)
- NPPES monthly bulk dissemination file incl. endpoint file (download.cms.gov/nppes/NPI_Files.html) not machine-readable: page answers 'This site will be down for maintenance until further notice' with no file links (2026-10-22); the full endpoint file could not be read, so platform coverage is limited to linked providers' records
- CMS National Directory of Healthcare (directory.cms.gov/fhir, NDH FHIR) machine-readable, public, no key; Organization-
read per linked NPI (verification status, EIN-group parent) as context; Endpoint search by organization returns empty bundles (no org->endpoint join), so no edges from it
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 48 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.

share of resolved cohort carrying it; tags >=0.20 & >=3 members (max 12, junk dropped), tag_groups >=0.20 (cooccurrence, non-cross-cutting; max 8), industries >=0.20 (max 6), areas >=0.10 (max 6; areas are keyword-matched and sparse), capabilities L1 >=0.20 (max 8); derive-market-taxonomy.py
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.
