Real-Time Price Monitor & Alert Bot

eCommerce Business, Michigan

Project overview

Real-time price monitoring bot that watches Amazon, eBay, and competitor websites 24/7. Sends instant Telegram and email alerts when prices drop below a set threshold or when competitor prices change.

The challenge

Client was missing price drops and restocking opportunities on key products because manual checking was only possible a few times per day.

My solution

Built a lightweight monitoring service that checks target URLs every 15 minutes, compares prices against stored baselines, and fires instant alerts via Telegram bot and email when thresholds are crossed.

Result

Sub-5 minute alert delivery on all price changes. Client captured 3 major restocking opportunities in first month that would have been missed manually.

Tech stack

Python, Telegram Bot API, SMTP, Scheduling, SQLite, BeautifulSoup
