Japan FSA Registered Fintech (crypto exchanges, stablecoin intermediaries, funds transfer, bank-API agents, prepaid)
Regulated register market (japan fsa, payment services act + banking act registrations). 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.
22providers measured
5 (22.7%)declare their own
6 (27.3%)covered by others only
1 (4.5%)distribution only (sell through, not integrations)
10 (45.5%)undeclared
3declare compatibility (report only, not weighted)
0in-market workflows shown
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.

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 22 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.
