source: live GET of the /.well-known/ discovery surface on every Vyond host
summary: >-
  No /.well-known/ discovery document is published on any Vyond host. Every canonical
  path returns 404 on the API host, the app host, the marketing host, the product
  (changelog) host and the Zendesk help host. Notably there is no RFC 9116
  security.txt and no RFC 8615 api-catalog, and no A2A agent card at either the
  canonical or the legacy path. The OpenAPI is published instead at a
  non-well-known location, https://api.vyond.com/doc/openapi.json.

    llms.txt IS published, but at the root of the marketing host rather than under
    /.well-known/ — https://www.vyond.com/llms.txt returned 200 text/plain.
