What this skill does
Retell AI Cost Tuning Overview Implementation patterns for Retell AI cost tuning — voice agent and telephony platform. Prerequisites Completed retellai-install-auth setup Instructions Step 1: SDK Pattern Output Retell AI integration for cost tuning Error Handling Error Cause Solution ------- ------- ---------- 401 Unauthorized Invalid API key Check RETELLAPIKEY 429 Rate Limited Too many requests Implement backoff 400 Bad Request Invalid parameters Check API documentation Examples Reduce cost without degrading a required human handoff Measure average call duration, transfer rate, and failed-call retries for a representative non-production sample before changing prompt length or model settings. Trial the lower-cost configuration on a small canary, retaining the existing agent version as rollback. Keep the human-handoff trigger unchanged unless the service owner approves a new threshold; a shorter call is not a saving if it silently increases unresolved customer requests.
