description: >-
  Dentrix does not publish a general per-second request rate limit. The Dentrix
  Ascend API Exchange meters usage by a monthly allowance per Dentrix Ascend
  location - a documented 30,000 API calls and 3 GB of data per location per month,
  with metered overages beyond that ($0.0018 per additional call, $1.00 per
  additional GB). On the on-premise Dentrix Developer Program, throughput is bound
  to the local Dentrix database/ODBC layer and each office's hardware rather than a
  cloud quota. Exact per-endpoint or per-second caps are partner-agreement specific
  and not publicly documented; figures here are drawn from public developer
  materials and are not reconciled against a signed agreement.
notes: >-
  Numeric caps beyond the Ascend per-location monthly allowance are not publicly
  documented. Verify current allowances and overage rates with Henry Schein One.
