  policy_url: null
  sunset_header: false
  note: |
    No public deprecation policy and no RFC 8594 Sunset header support is
    documented. Deprecations are communicated in specification revisions - the
    Saturn spec v2.8.3 removed the getOverview, getMarketPlaceDetail and
    getTimeLine resources and pre-announced removal of the submit and get
    resources.
status_page: null
status_page_note: |
  No public API status page was found - status.euronext.com does not resolve,
  euronext.statuspage.io is an unclaimed Atlassian placeholder, and no
  market-status page is published as an API status surface (probed 2026-07-22).
