Zunum Aero is an American aerospace company founded in 2013 and based in the Seattle area (Kirkland / Bothell, Washington) that set out to build hybrid-to-electric regional aircraft. Its ZA10 program targeted a six-to-twelve-seat hybrid-electric airplane with a 700-nautical-mile range, aimed at reviving short-haul point-to-point air travel from secondary airports, and it was backed by Boeing HorizonX and JetBlue Technology Ventures. The company laid off nearly all of its staff in late 2018 and paused operations, and it later pursued trade-secret litigation against Boeing. Zunum Aero is an aircraft manufacturer, not a software vendor: its public web presence is a marketing and press site with no developer program, no developer portal, no documentation, and no published machine-readable API contract of any kind.
Zunum Aero is profiled on the APIs.io network. Tagged areas include Company, Aerospace, Aviation, Aircraft Manufacturing, and Electric Aviation.
Zunum Aero’s developer surface includes engineering blog and 6 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/zunum-aero: open an issue to ask a question, or submit a pull request to add artifacts.
