description: >
  Fyno's public API documentation does not publish explicit per-second or per-minute
  rate limit values. Monthly API request quotas are enforced at the plan level.
  The platform includes automated throttling to manage downstream provider rate limits
  (e.g., WhatsApp TPS, SMS MPS) transparently. A 429 Too Many Requests response is
  returned when limits are exceeded. Idempotency keys expire after 24 hours.
