Run autonomous Swarms agents on Cloudflare Workers — schedule them with cron triggers, fetch real-time data from external APIs, and dispatch results to email or downstream systems. Workers run in 330+ cities worldwide, giving sub-100ms latency to data sources.

​
What this pattern is good for

  • ⚡ Scheduled execution — agents trigger automatically on cron schedules.
  • 📊 Real-time data fetch — pull from Yahoo Finance, news feeds, custom APIs.
  • 🤖 Multi-agent analysis — call the Swarms API with several specialized agents.
  • 📧 Automated actions — email reports, webhook posts, push notifications.
  • 🌍 Global edge — Cloudflare’s network is closer to your users and data sources than a single VM.

​
Reference implementation

A complete, production-ready stock analysis agent is published at: 🔗 github.com/The-Swarm-Corporation/Swarms-CloudFlare-Deployment The repository ships two implementations:
FolderRuntimeStatus
stock-agent/ — JavaScript / TypeScriptV8Production-ready
python-stock-agent/ — Python (Pyodide)Cloudflare Python WorkersBeta
Both implementations cover the same workflow: fetch market data, run multi-agent analysis via the Swarms API, generate a report, send it via email, and expose a small web dashboard for manual triggers.

​
Step 1: Clone and install

​
Option A — JavaScript

git clone https://github.com/The-Swarm-Corporation/Swarms-CloudFlare-Deployment.git
cd Swarms-CloudFlare-Deployment/stock-agent
npm install

​
Option B — Python

git clone https://github.com/The-Swarm-Corporation/Swarms-CloudFlare-Deployment.git
cd Swarms-CloudFlare-Deployment/python-stock-agent
npm install   # Wrangler CLI

​
Step 2: Configure environment

Create a .dev.vars file: 
# Required: Swarms API key
SWARMS_API_KEY=your-swarms-api-key-here

# Optional: market news (free tier available)
FMP_API_KEY=your-fmp-api-key

# Optional: email notifications
MAILGUN_API_KEY=your-mailgun-api-key
MAILGUN_DOMAIN=your-domain.com
RECIPIENT_EMAIL=your-email@example.com
For production, store these as Cloudflare Workers secrets via wrangler secret put.

​
Step 3: Set the cron schedule

Cron triggers are configured in wrangler.jsonc: 
{
  "triggers": {
    "crons": [
      "0 */3 * * *"   // every 3 hours
    ]
  }
}
Common patterns:
CronSchedule
0 9 * * 1-59 AM weekdays
0 */6 * * *Every 6 hours
0 0 * * *Daily at midnight
Use crontab.guru to validate expressions.

​
Step 4: Run locally

npm run dev
# visit http://localhost:8787

​
Step 5: Deploy

npm run deploy
# live at https://stock-agent.your-subdomain.workers.dev

​
Customization

​
Stock symbols

In JavaScript: 
const symbols = ["SPY", "QQQ", "AAPL", "MSFT", "TSLA", "NVDA", "AMZN", "GOOGL"];

​
Custom Swarms agents

const swarmConfig = {
  agents: [
    {
      agent_name: "Risk Assessment Agent",
      system_prompt: "Analyze portfolio risk and provide recommendations...",
      model_name: "gpt-5.4",
      max_tokens: 2000,
      temperature: 0.1,
    },
  ],
};

​
Cost notes

  • Cloudflare Workers — free tier covers 100,000 requests/day.
  • Swarms API — monitor usage in the dashboard; switch to gpt-4o-mini for cost-sensitive runs.
  • External APIs — most of the providers listed above (Yahoo Finance, FMP free tier, Mailgun free tier) are free at low volume.

​
Security checklist

  • Store API keys as Wrangler secrets, never in source.
  • Validate incoming requests + apply per-IP rate limits.
  • Audit AI decisions and persist compliance logs.
  • Use HTTPS for every outbound call.

​
Troubleshooting

SymptomLikely cause
API key errors.dev.vars missing or wrangler secret put not run for production
Cron not firingCheck wrangler.jsonc syntax and Workers cron limits
Email not sendingMailgun domain not verified, or API key wrong region
Data fetch failuresExternal API quota hit or rate-limited
