• Surescripts certified software / Network Alliance participants not machine-readable: no public directory: the network-alliance page names no participants, /certified-solutions 404 (2026-10-20); site search is an Algolia index behind an embedded key, not used
• NCPDP member directory not machine-readable: member login

• Bamboo Health partners (PDMP integration vendors) not machine-readable: plain GET answers a Cloudflare challenge; the page carries category blurbs and logos, no partner identities

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 2026-10-20 from the 77 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
