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

import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list(); console.log(Agents: ${agents.length});

## Output

- Retell AI integration for cost tuning

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| 401 Unauthorized | Invalid API key | Check RETELL_API_KEY |
| 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.
