  API and integration access is a PRO-TIER FEATURE. The Basic plan does not include
  API/integrations, so the entire developer surface documented at docs.epsilon3.io -
  and by extension the MCP server - is gated behind at least $200/user/month with a ten
  user minimum, i.e. roughly $24,000/year before an integrator can make a call.

  note: Unlimited view-only users are free, but view-only users cannot exercise the API.
