Chemistry and Materials (chemical data depositors, materials-data APIs)
Register market (pubchem depositors, optimade materials-data api implementers). 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
- PubChem data sources (pubchem.ncbi.nlm.nih.gov/rest/pug/sourcetable/all/JSON) machine-readable, 1,135 sources (570 with a URL); 3 linked (Sigma-Aldrich, Thermo Fisher, AstaTech); 199 held; 499 name-only rows with no Wikidata identity
- OPTIMADE providers registry (providers.optimade.org/providers.json) machine-readable, 30 providers; 2 linked (Materials Project, MPDS); 18 without a catalog repo; shape optimade report-only
- ECHA REACH registrants (echa.europa.eu registered-dossier pages; chem.echa.europa.eu substance API) not machine-readable: dossier pages 403 (Azure WAF); the substance API serves substances / registration numbers but no registrant legal-entity names (2026-10-19)
- CAS / Pistoia Alliance / Allotrope members not machine-readable: proprietary or HTML logo walls; not a machine-readable register
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 44 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 | Materials Science 39%, Chemicals 36%, Manufacturing 34%, Biotechnology 27%, Synthetic Biology 27%, Life Sciences 25% |
|---|---|
| Tag groups | Materials Science 68%, Healthcare 39%, Manufacturing 34%, Synthetic Biology 32% |
| Industries | Chemicals 43%, Semiconductors & Hardware 41%, Industrial 36%, Biotechnology & Drug Discovery 32%, Artificial Intelligence 30%, Life Sciences 25% |
| Areas | Machine Learning 11% |
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.
