Track competitor prices daily with ZenRows, OpenAI, Telegram, and DataTables

Stop checking competitor prices manually. This workflow monitors product prices across multiple online retailers every day — automatically. The moment a price changes, you get an instant Telegram alert with the product name, old price, new price, and a direct link to the page. Set it up once. Let it run forever. --- What it does - Scrapes product pages daily using ZenRows with JS rendering and residential proxies - Extracts prices via JSON-LD structured data — works across most major retailers - Compares each price against the last known value stored in an n8n DataTable - Tracks full price history for every product over time - Sends an AI-written summary alert via Telegram only when prices actually change - Updates all records automatically — no manual database management --- What's inside - Ready-to-import n8n workflow (14 nodes, fully documented with sticky notes) - Full setup guide — step by step from zero to running in ~15 minutes - DataTable schema template for instant import - Sample Amazon product URLs to test immediately after setup --- What you need - n8n (self-hosted or cloud) - ZenRows API key (web scraping) - OpenAI API key (alert generation) - Telegram Bot token --- Who it's for Perfect for e-commerce store owners, small businesses, and anyone who needs to stay on top of competitor pricing without lifting a finger. --- P.S. I actually use this workflow myself to monitor the price of a tablet I want to buy. I simply pasted the product URLs from a few local retailers and now every morning,if any price changed overnight, I get a Telegram message. That's it. No app, no subscription(only Open Ai, zenrows have free tier), no manual checking.
