GM OnStar
GM OnStar is General Motors' connected vehicle services platform, originally launched in 1996 as an in-vehicle safety, security, and concierge service and since extended into a commercial data platform under OnStar Business Solutions. The OnStar Business Solutions API and Data Services product delivers near-real-time embedded telematics straight from properly equipped 2015-model-year-or-newer GM vehicles — Chevrolet, Buick, GMC, and Cadillac — without aftermarket hardware, exposing vehicle location, speed, ignition status, odometer, fuel level, EV state-of-charge and charging status, tire pressure, seatbelt status, diagnostic trouble codes, and driver-behavior events such as hard brake and hard acceleration. The product is packaged into tiered plans (commonly referenced as API Starter and API Pro) and is distributed primarily through OnStar's enterprise channel under the GM Envolve commercial brand, plus integrations with fleet management providers including Samsara, Geotab, Wheels, Verizon Connect, and other approved telematic service providers. There is no public self-serve developer portal or published OpenAPI specification — access is gated through GM/OnStar sales (developer.gm.com is a request-access endpoint) or via an authorized integration partner. Consumer-facing OnStar mobile features (remote start, remote lock, vehicle locate, in-vehicle Wi-Fi, Super Cruise telemetry) are delivered through GM's myChevrolet, myBuick, myGMC, and myCadillac apps and are not part of the published API surface.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles GM OnStar the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — GM OnStar scores 7.4/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
