PDF and Document Standards (PDF tooling, document signing trust, invoice documents)
Register market (adobe aatl document-signing trust; eidas qes / qseal via the legal-esignature lotl edges). 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.
124providers measured
58 (46.8%)declare their own
12 (9.7%)covered by others only
7 (5.6%)distribution only (sell through, not integrations)
47 (37.9%)undeclared
16declare compatibility (report only, not weighted)

Provisional. Provisional and unweighted: the Market layer is not part of the composite or agent readiness. Leader lists are read within a position, never as one ranking. A provider that declares nothing we can
read is shown as undeclared, with no number: we never infer integrations.
Where this market publishes its structure
- Adobe Approved Trust List members (helpx.adobe.com/acrobat/kb/approved-trust-list1.html) machine-readable, 88 members in 34 countries, 87 with a website, 28 with the CSC TSP mark; 17 held (governments / regulators / end-users / parent domain); 5 in-market linked (digicert, infocert, namirial, notarize, swisscom), 1 out of market (wordline); most commercial CAs have no repo (harvest list in the report)
- Adobe AATL programme page (helpx.adobe.com/acrobat/kb/approved-trust-list2.html) machine-readable, programme description + technical requirements; links the member list
- EU Trusted List browser (eidas.ec.europa.eu/efda/trust-services/browse/eidas/tls) machine-readable, same register as the EU LOTL XML read by sweep-legal.py (legal-esignature); not re-written here; its 13 QES / QSeal QTSPs with repos are in this cohort
- PDF Association members (pdfa.org/members/) not machine-readable: Cloudflare 403 to every non-browser request (robots.txt included); a bot block, not passed with a browser
- PDF Association / veraPDF PDF/A and PDF/UA conformance product listings (pdfa.org) not machine-readable: same pdfa.org Cloudflare block; verapdf.org publishes the validator and docs only, no vendor / product list
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 2026-10-21 from the 124 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 | PDF 45%, E-Signature 27% |
|---|---|
| Tag groups | Documents 73%, OCR 25% |
| Industries | Legal & Compliance Tech 28%, Artificial Intelligence 27% |
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.
