  • Standard rate limits are not published

Zendesk

  • AI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation

  • Advanced routing, workforce engagement, and approval workflows limited to Enterprise tier
  • Highest tier requires sales consultation and custom pricing
