description: >-
  Voiceflow rate-limits primarily through plan-tier conversation quotas and concurrency
  caps. Per-RPS HTTP limits are not publicly documented; usage-based billing means
  high-volume customers should consult sales for negotiated throughput.
notes: Plan-tier conversation quotas are the documented scaling lever.
