Monitor Bitcoin & Ethereum prices with CoinGecko alerts via Email/SMS

⚠️ Crypto Price Threshold Alerts (Email/SMS/Telegram)

📌 Overview

This workflow monitors Bitcoin (BTC) and Ethereum (ETH) prices in real-time using CoinGecko’s public API. It sends you an instant alert when a price crosses a custom threshold or when the 24-hour change moves beyond your defined % range.

Perfect for traders who want automated price pings without constantly checking charts.

⚙️ How it works

1. Schedule Trigger — runs every 10–15 minutes (configurable cron).
2. HTTP Request (CoinGecko) — fetches live BTC/ETH prices + 24h % changes.
3. Code Node — compares values against your target thresholds.
4. IF Node — checks if any condition is true (cross up/down or big move).
5. Notification Node — sends alert via Email, SMS (Twilio), or Telegram.

Example Output:
> “BTC broke $110,000 (+2.1% 24h)”

🛠 Setup Guide

1. Set your thresholds in the Code node:

   • BTC_UP / BTC_DOWN
   • ETH_UP / ETH_DOWN
   • MOVE_ABS (absolute % change to trigger)

2. Choose delivery channel:

   • Email Node → SMTP (Gmail, Outlook, etc.)
   • Twilio Node → SMS alerts
   • Telegram Node → DM or channel alerts

3. Test Run:

   • Execute once from the Code node.
   • If thresholds are crossed, you’ll see a formatted alert payload.

🎛 Customization

• Adjust interval in the Schedule Trigger (default: every 15m).
• Add more cryptos by editing the CoinGecko API call.
• Use Slack or Discord instead of Email/Telegram for team alerts.
• Store last triggered state in Google Sheets/DB to avoid repeated pings.
