Multi Platform Stock Checker Script -- 2

I need a small script that can tell me—at a glance—whether a specific electronics item is in stock on Zepto, Blinkit, BigBasket, Instamart, Flipkart, Amazon, and Jiomart.

The core job is simple: take a product URL or SKU, poll each of those sites in real-time (or on a short interval I can adjust), and return an “Available / Out of Stock” status. A lightweight log of the last check and, ideally, an option to push an alert (console, email, or webhook—whatever’s easiest to wire up) would be perfect.

Deliverables
• Clean, well-commented source code that runs from the command line
• A quick README explaining any setup, keys, or cookies the script needs
• One short demo run showing the checker working across all named platforms

I’m not particular about the language or framework as long as it’s easy to install on a standard Windows or Linux box without paid dependencies.
