Channel Analysis

The Channel Analysis API provides comprehensive deep-dive analytics for YouTube channels through a two-step asynchronous process. This powerful feature analyzes channel performance, content strategy, audience demographics, and revenue metrics.

Overview

Channel Analysis is designed for in-depth channel investigation that requires more processing time than standard analytics. The API uses a job-based system where you first create an analysis job and then retrieve the results when processing is complete.

Quick Start

Get started with the two-step process:

1. Install NexLev: Add the NexLev node to your n8n instance (Installation Guide)
2. Get API Key: Create your API key at API Key
3. Create Analysis Job:
   • Add NexLev node → Select "Channel Analysis" → Choose "Create Job"
   • Enter a Channel ID (e.g., UCoLvjCESbwNnh9l873T2OEQ)
   • Execute to create the analysis job
4. Wait for Processing: Add a Wait node (30-60 seconds recommended)
5. Get Results:
   • Add another NexLev node → Select "Channel Analysis" → Choose "Get Result"
   • Use the job_id from step 3
   • Execute to retrieve comprehensive analysis

Example Result: You'll receive deep strategic insights including content buckets, title formats, audience sentiment, script blueprints, and AI-powered recommendations.
