note: 'No rate limits are published. Acadia''s own factsheets confirm a direct API
  exists ("accessed via Web user interface, direct API or SFTP"), but every technical
  document describing it sits behind the authenticated portal at portal.acadiasoft.com,
  so no throttle, quota, window, burst allowance or response-header contract
  (X-RateLimit-*, RateLimit-*, Retry-After) could be observed or read. This is an
  honest zero produced by a documentation wall, not by an absence of limits — the
  limits almost certainly exist and are stated in the customer contract.'
