# Retell AI Architecture Variants

## Overview

Implementation patterns for Retell AI architecture variants — voice agent and telephony platform.

## Prerequisites

- Completed `retellai-install-auth` setup

## Instructions

### Step 1: SDK Pattern

```typescript
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 architecture variants

## 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

### Choose a queue-backed architecture for bursty inbound calls

For a campaign that creates short spikes, keep the public number attached to a
stable routing layer and place CRM enrichment behind an asynchronous queue.
Start with a preview agent that records only synthetic test calls, set a clear
timeout for the enrichment request, and configure a human-transfer fallback.
Measure latency and transfer rate during the canary before selecting the
variant for production traffic.
