Xwing

Xwing, Inc. is a San Francisco and Concord, California aviation company founded in 2016 that built Superpilot, a modular retrofit autonomy system enabling ground-supervised, uncrewed gate-to-gate flight on conventional fixed-wing aircraft. Flying a Cessna 208B Grand Caravan testbed, Xwing completed more than 250 fully autonomous flights and over 500 auto-landings, and in April 2023 became the first company to receive an FAA project designation toward certification of a large unmanned aircraft system. Joby Aviation acquired Xwing's autonomy division in June 2024; Xwing retained its Part 135 air cargo operation, and www.xwing.com is now an archived marketing site pointing visitors to Joby. Xwing never published a developer program, public API, SDK or machine-readable contract; the domain's only agent-readable surfaces are the llms.txt and Site MCP endpoint that Wix generates for every site it hosts.

Xwing is profiled on the APIs.io network. Tagged areas include Company, Aviation, Autonomy, Aerospace, and Unmanned Aircraft.

Xwing’s developer surface includes engineering blog and 10 more developer resources.

scored 2026-11-06 · rubric v0.27.0
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
  • Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
  • 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)
  • 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)
  • Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
11 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
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/xwing/apis.yml: open an issue on github.com/api-evangelist/xwing to ask a question or point us at an artifact you publish.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

x-api-posture-note: Xwing's product was embedded aircraft autonomy software certified and integrated onto airframes, never
  offered as a developer-callable API. STEP 0b contract discovery on 2026-09-04 found no OpenAPI, GraphQL, AsyncAPI, gRPC,
  WSDL or OGC surface on any host the record knows; /developers and /api both return HTTP 404.

x-division-acquired-note: Joby acquired the autonomy division only. Xwing, Inc. retained its Part 135 cargo operation, so
  this is not a defunct company — but the software business that could have produced an API surface now sits inside Joby Aviation.
