How to Build a 30-Agent YouTube Growth Team with Scavio

Replicate the viral r/n8n 30-agent YouTube growth workflow using Scavio for transcript mining, competitor research, and trending topic discovery.

A viral r/n8n post in April 2026 described a 30-agent workflow that scaled a YouTube channel from zero to 50K subs in 9 months. The bottleneck was always research data. This tutorial shows how to build the same architecture with Scavio as the single data source: transcript mining, competitor video analysis, and trending topic discovery on one key.

Prerequisites

  • n8n or LangGraph
  • A Scavio API key ($30/mo tier recommended for this workload)
  • An LLM credential

Walkthrough

Step 1: Map the 30 agent roles

Typical split: 5 research, 10 script draft, 5 thumbnail/title, 5 shorts repurpose, 5 publish+monitor.

JSON
// agent-roster.json
[
  { "role": "trend_scout", "count": 3 },
  { "role": "competitor_analyst", "count": 2 },
  { "role": "script_writer", "count": 10 },
  { "role": "thumbnail_brief", "count": 3 },
  { "role": "title_ab", "count": 2 },
  { "role": "shorts_cutter", "count": 5 },
  { "role": "publish_monitor", "count": 5 }
]

Step 2: Wire the trend scout to Scavio YouTube search

Each scout agent queries Scavio for rising topics in your niche.

Bash
// Trend scout agent
POST https://api.scavio.dev/api/v1/search
Body: { "platform": "youtube", "query": "niche keyword", "sort": "recent" }
// Filter by view velocity (views/hours since publish).

Step 3: Competitor analyst pulls transcripts

Transcript mining is what Scavio uniquely does at this price point.

Bash
POST https://api.scavio.dev/api/v1/youtube/transcript
Body: { "video_id": "{{ competitor_video_id }}" }

Step 4: Script writer consumes transcripts as context

Feed transcripts into the script-writer agents so they riff on proven angles.

Text
// Script writer prompt
You are writing a YouTube script on {{ topic }}.
Competitor transcript: {{ transcript }}
Identify 3 things they missed and build a 7-minute script around those gaps.

Step 5: Thumbnail brief mines top YouTube thumbnails

Thumbnails are visual; Scavio returns thumbnail URLs in search results.

JavaScript
// Use the thumbnail_url field from YouTube search results
scavio.search({ platform: 'youtube', query: topic })
  .organic_results.forEach(v => console.log(v.thumbnail_url));

Step 6: Publish monitor tracks rank

Each published video kicks off a daily rank-check loop.

JavaScript
// Daily rank check
scavio.search({ platform: 'youtube', query: published_title })
  .organic_results.findIndex(v => v.id === my_video_id);

Python Example

Python
import os
from scavio import Scavio

scavio = Scavio(api_key=os.environ['SCAVIO_API_KEY'])

def trend_scout(niche: str):
    videos = scavio.search(platform='youtube', query=niche, sort='recent')
    return sorted(videos['organic_results'], key=lambda v: v.get('views', 0) / max(v.get('hours_old', 1), 1), reverse=True)[:10]

def competitor_transcript(video_id: str):
    return scavio.youtube_transcript(video_id=video_id)

JavaScript Example

JavaScript
import { Scavio } from 'scavio';
const scavio = new Scavio({ apiKey: process.env.SCAVIO_API_KEY });

export async function trendScout(niche) {
  const r = await scavio.search({ platform: 'youtube', query: niche, sort: 'recent' });
  return r.organic_results
    .sort((a, b) => (b.views / (b.hours_old || 1)) - (a.views / (a.hours_old || 1)))
    .slice(0, 10);
}

Expected Output

JSON
A 30-agent swarm publishes 2 videos per day at ~600 credits per video, staying within the $30/mo Scavio tier for a full month of content.
