note: |
  The current API reference at docs.big-xyt.com is login-gated (HTTP 403
  unauthenticated), so the live authentication model cannot be verified. This
  profile is captured from the last PUBLIC documentation of the xyt hub API
  (2018, preserved in the vekonyz fork of xythub.github.io after the official
  repo's history was squashed in 2023). It documented OAuth 2.0 Resource Owner
  Password Credentials grant issuing bearer tokens: POST to
  AUTH_SERVICE_URL/oauth/token with HTTP basic client credentials
  (client_id "xyt" + a service secret) and grant_type=password plus
  username/password form fields; the JSON response returned access_token,
  token_type bearer, expires_in ~43199 seconds (12h), scope "read". Every API
  request then carries "Authorization: Bearer TOKEN". Requests/responses used a
  length-prefixed Protocol Buffers v3 binary wire format. Treat as legacy
  provenance until the gated current docs can be verified.
