  Published plans and pricing for Nasdaq Calypso Workstation. There are none.
  The Nasdaq Calypso product pages carry no pricing page, no tier table, no
  per-seat or per-call rate, and no self-service sign-up; the only commercial
  call to action anywhere on the product and front-office pages is "Contact Us",
  which resolves to https://www.nasdaq.com/contact-us. Calypso is sold as an
  enterprise, contract-negotiated capital markets platform to banks, asset
  managers, central banks and clearing houses.

  This file previously carried a three-tier free/professional/enterprise scaffold
  with invented request quotas and rate ceilings, written by the 2026-05-04 bulk
  sweep and stamped method:generated. None of it was published by the provider.
  It has been replaced with the measured result: zero published plans. An honest
  zero is the finding.
