Daily crypto yield monitor: Track top Binance Earn APY rates with earnings calculator

Get top Binance Earn yields sent to Email

This workflow automates the tracking of passive income opportunities on Binance by fetching real-time Flexible Earn APY rates, calculating potential returns, and delivering a daily summary to your inbox.

Manually checking crypto savings rates is tedious. This template handles the complex authentication required by Binance (HMAC-SHA256 signing), filters through hundreds of assets to find the highest yields, and calculates exactly how much you would earn daily on a simulated capital amount.

👥 Who is this for?

• Crypto Investors looking to maximize passive income on idle assets.
• DeFi/CeFi Analysts monitoring market rate fluctuations.
• Hodlers who want to ensure their assets are generating the best possible yield without daily manual checks.

⚙️ How it works

1. Schedule Trigger: Initiates the workflow every 24 hours (customizable).
2. Authentication Handler: Generates a timestamp and creates a secure HMAC-SHA256 signature required by the Binance API.
3. Data Fetching: specific HTTP Request retrieves the full list of "Flexible Earn" products.
4. Processing: The workflow splits the data, standardizes field names, and sorts all assets by Annual Percentage Rate (APR) in descending order.
5. Analysis: It limits the list to the top 15 assets and calculates estimated daily earnings based on a $10,000 reference capital (customizable via code).
6. Reporting: A formatted HTML email is sent via Gmail with the top opportunities.

🛠️ Setup Guide

1. Binance API: Log in to Binance and create a Read-Only API Key.
2. Configure Nodes:
   • Open the Set Credentials 1 node: Paste your API_KEY and SECRET_KEY in each field.

🎨 How to customize

• Change Capital Calculation: Open the "Filter & Analyze" Code node and change const capital = 10000; to your actual portfolio size to see real projected earnings.
• Filter Assets: Add an If node after the "Split Out" node to only filter for specific assets (e.g., USDT, BTC, ETH) if you don't want to see altcoins.
• Change Frequency: Open the "Daily Trigger" node to run this hourly or weekly.
