description: >-
  PromptLayer governs usage primarily through plan-based monthly request
  (transaction) volumes rather than publicly documented per-minute request
  ceilings. Included monthly request volumes vary by plan (2.5k Free/Pro,
  100k Team, custom Enterprise) with pay-as-you-go overage above the included
  amount. Evaluation cell executions and dataset sizes are also capped per plan.
  Specific per-second / per-minute API throttling thresholds are not published
  and are not reconciled in this artifact.
notes: >-
  Verify plan request volumes, eval execution allowances, and any per-endpoint
  throttling against the PromptLayer pricing page and API reference on
  reconciliation; values change as accounts move between Free, Pro, Team, and
  Enterprise plans.
