Heart Aerospace
Heart Aerospace is a hybrid-electric aircraft manufacturer founded in 2019 and headquartered in Torrance / Los Angeles, California, working to decarbonize and lower the cost of regional air travel. The company is developing the X1, a full-scale hybrid-electric technology demonstrator, and the ES-30, a 30-seat regional production aircraft, backed by strategic airline partners including United Airlines and Air Canada and investors such as Breakthrough Energy Ventures, Lowercarbon Capital, EQT Ventures, and Y Combinator. Heart Aerospace publishes no public developer or API surface; this profile tracks the company as an API Evangelist network entry in the sustainable-transport sector.
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 Heart Aerospace 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 — Heart Aerospace scores 8.1/100 (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.
