Government and Open Data
Register (national api catalogues) with a hosted portal platform (socrata). 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
- UK Government API Catalogue, co-cddo/api-catalogue data/catalogue.csv (url, documentation, provider) machine-readable
- Providers' own contracts naming Socrata / SODA in info, tags or servers machine-readable
- api.gouv.fr catalogue (France) not machine-readable: 200 text/html on /les-api and /api/v1/apis; no JSON listing (2026-10-15)
- data.gov CKAN action API (US) not machine-readable: catalog.data.gov/api/3/action/* returns 404; the GSA mirror api.gsa.gov/technology/datagov/v3 is keyed (403 API_KEY_MISSING), 2026-10-15
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 2026-10-15 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.
| Tags | Open Data 62%, Government 42% |
|---|---|
| Tag groups | Open Data 71%, Government 42%, United Kingdom 21% |
| Industries | Government & Public Sector 58% |
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.
