Communications (CPaaS)
Coverage market (channel and delivery-provider enums). 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
- Providers' own channel enums machine-readable
- Notification layers' delivery-provider enums machine-readable
- Meta WhatsApp BSP and Business Partner directories not machine-readable: JS shell / authenticated
- Google RCS partners not machine-readable: no directory
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 25 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.

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.

Workflows
No in-market workflows yet; bridges: 25 (17 not yet mapped to a capability). In-market workflows only: a step on the market provider's side maps to this market's business capabilities (BC-2640, BC-2700, BC-430.30, BC-400.60), and the partner is not a generic export/notify app. Other workflows are counted as bridges (including any whose steps do not resolve to a capability yet). Methodology.
