      Every path under https://api.sendible.com/api/v1 answers HTTP 401 with the
      response header `WWW-Authenticate: Basic realm="Application"` and the body
      `HTTP Basic: Access denied.` — including paths that do not exist, so the
      challenge is emitted by the edge before routing. This is an OBSERVED
      runtime fact, not a documented contract.

note: >-
  NO `Authentication` pointer is emitted in apis.yml for this file, deliberately.
  The scoring check it feeds is `authentication_documented`, and Sendible
  publishes no authentication documentation anywhere on a first-party surface:
  developers.sendible.com is retired (301 to the marketing home page) and the
  Zendesk help centre carries no API article — the former "How do I set up
  services for my clients via the API?" article (id 208053026) now returns 404
  from the help-centre API. Credentials (application id, API key, shared key/iv)
  are issued only from inside a signed-in Sendible account. This artifact
  records what we could observe from outside; it must not be read as the
  provider documenting their auth model.
