description: >-
  LLMWhisperer meters usage by pages processed. The free tier caps usage at
  100 pages per day; paid pay-as-you-go usage is billed per 1,000 pages with
  no documented hard request-per-minute cap published in the public API
  reference. Extraction is asynchronous, so callers submit to /whisper and poll
  /whisper-status (or use webhooks) rather than holding a synchronous
  connection. Specific per-account concurrency and request-rate limits are not
  reconciled in this artifact.
notes: >-
  The 100 pages/day cap is the documented free-tier quota. Verify any
  per-account request-rate, concurrency, or burst limits with Unstract support
  or the dashboard during reconciliation; recommended polling interval and
  backoff should be confirmed against the docs.
