  Castor does not publish transparent, self-service list pricing for the platform
  or the API. Castor EDC / CDMS is sold on a per-study subscription basis, quoted
  by sales based on study size, number of users, duration, modules (surveys / ePRO,
  randomization, eConsent), region, and compliance needs. Third-party software
  directories report entry points in the low hundreds of dollars per month for the
  smallest studies, with mid-market and enterprise multi-center trials priced by
  custom quote. Academic, non-profit, and grant-funded pricing is available. The
  API is not a separately metered product - it is included with a study
  subscription and consumed under the platform's rate limits at no additional
  per-call charge.
notes: >-
  Dollar figures below are indicative ranges gathered from third-party software
  directories (ITQlick, Capterra, GoodFirms) and are NOT official Castor list
  prices. Contact Castor sales for a quote. Reconcile against the official
  castoredc.com pricing / contact-sales flow and the helpdesk "Costs and payment"
  section.
