JetZero

JetZero is a Long Beach, California aerospace company founded in 2021 by Tom O'Leary and Mark Page to bring the blended wing body (all-wing) airframe to commercial aviation. Its flagship program is the Z4, a 250-seat, international-range jetliner the company says will burn up to 50% less fuel than comparable tube-and-wing airliners, and the Jet1 full-scale demonstrator being built with Scaled Composites in Mojave, California ahead of a first flight targeted for 2027. JetZero broke ground in 2026 on a manufacturing and final-assembly campus in Greensboro, North Carolina and is opening an engineering office in Wichita, Kansas at NIAR. It is backed by the U.S. Air Force, NASA, United Airlines, Alaska Star Ventures and a $175M Series B led by B Capital, with letters of intent from Gulf Air and Japan Airlines. JetZero is an aircraft manufacturer, not a software or data provider: as of this profile it publishes no public developer portal, no API documentation, no SDKs, and no machine-readable API contract of any kind. Its public technical surface is a supplier registration and supplier standards program.

JetZero is profiled on the APIs.io network. Tagged areas include Company, Aerospace, Aviation, Aircraft Manufacturing, and Advanced Manufacturing.

JetZero’s developer surface includes engineering blog, support, and 10 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document Ask about this →
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship Ask about this →
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author Ask about this →
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey) Ask about this →
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes Ask about this →

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 the provider profile at artifacts.apis.io/jetzero/apis.yml: open an issue on github.com/api-evangelist/jetzero to ask a question or point us at an artifact you publish.
