Instructions
Step 1: SDK Pattern

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 prod checklist
## 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
### Approve a limited production launch
Before routing a live number, verify the exact agent version, environment
secret references, consent and disclosure text, fallback transfer destination,
and on-call owner. Run a final synthetic call through the production-like
preview route and record the result without retaining audio. Start with a
small traffic percentage and a defined rollback trigger, then expand only when
completion, escalation, and error metrics remain within the release bounds.
