description: >-
  Nuclia enforces plan-based quotas rather than published per-second request
  limits. The primary metered resource is the Nuclia token (consumed by
  processing, search, generative answers and stored indexed data), bounded by
  the monthly token allowance of the subscription plan. Indexed data is capped
  by the plan's GB / resource quota, and file size by a per-file maximum.
  Per-endpoint request throttling, when applied, returns HTTP 429. Specific
  numeric request-rate limits are not publicly reconciled in this artifact.
notes: >-
  Verify any per-endpoint request-rate limits and current plan token / storage
  quotas in the Nuclia dashboard and pricing page on reconciliation; quotas
  change between Starter, Pro and Enterprise tiers.
