description: PTC ThingWorx is deployed per-customer (cloud or on-prem); rate limits depend on the platform
  sizing of the deployment rather than a public per-tenant policy. Public ThingWorx documentation is
  gated to authenticated PTC customers.
notes: ThingWorx support documentation returns 403 to anonymous fetch. No public per-second rate-limit
  numbers exist; throughput is governed by deployment sizing and licensed connected-asset count.
