Retellai Observability

Retell AI observability for voice agents and phone calls, using the retell-sdk Node package to list

by jeremylongshore · MIT

The skill

Retell AI observability for voice agents and phone calls, using the retell-sdk Node package to list agents and emit call metrics such as completion, transfer outcome, latency, and provider errors tagged by agent version and environment. Use when monitoring or alerting on Retell AI voice agent call behavior, investigating failed or regressed calls, or comparing agent versions, and when the user mentions retell observability or retellai-observability.

Retell AI Observability

Overview

Implementation patterns for Retell AI observability — 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 observability

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

Alert on a regression while protecting call content

Emit structured metrics for call completion, transfer outcome, latency, and provider errors using agent version and environment as bounded labels. When an alert fires, link the affected call identifiers to a restricted investigation record instead of attaching transcripts to the dashboard. Compare a synthetic call against the last known-good version, then make one reversible routing or configuration change and watch the same metrics through the defined recovery window.
