    /index/cc/v1/, /news/v1/ on data-api; /data/... and /data/v2/... on the legacy
    min-api). No date-based or header-based versioning.

    change: >-
      Free API tier retired: "we will be retiring our free API tier and accounts
      without a subscription will no longer have API access" — keys without an
      active subscription stop returning data. Confirmed live: both min-api and
      data-api now return HTTP 401 with the Data/Err envelope for unauthenticated
      requests on every path.
