notes: >-
  Unstructured does not publish explicit rate limit values in public
  documentation as of 2026-06-12. The SDK implements exponential backoff
  retry logic with a default max elapsed time of 1 hour, suggesting rate
  limiting may occur under heavy load. The split_pdf_concurrency_level
  parameter is capped at 15 to avoid high resource usage. Enterprise and
  dedicated instance customers may negotiate custom limits. Check
  https://docs.unstructured.io or contact support@unstructured.io for
  plan-specific limits.
