notes: The Quandl pricing page (data.nasdaq.com/pricing) returned 404 during reconciliation, and the
  Nasdaq Data Link documentation does not surface concrete subscription rates for premium datasets.
  Free open data is available with anonymous and authenticated access; premium datasets are sold on
  a per-dataset subscription that is configured at checkout. Reconciliation flagged false until subscription
  rates can be confirmed against the live pricing surface.
description: Nasdaq Data Link (formerly Quandl) hosts both free open data (central banks, government
  series) and premium datasets sold per-subscription. The platform does not publish a single tier table;
  pricing is per-dataset and surfaced inside the data.nasdaq.com checkout flow.
