Telegram Instamart Stock & Deal Bot

I need a Telegram-based bot that monitors Instamart in near real time—ideally every few minutes—and pushes concise alerts straight to my chat. The bot must:

• Check stock availability for selected SKUs
• Catch any price drops or temporary discounts
• Send a clean, human-readable message each time one of those events occurs

I should be able to add or remove item URLs or product IDs through a simple command or configuration file, and adjust the polling interval without touching the code. If Instamart changes layout or endpoints, I expect graceful error handling instead of silent failure.

Technically I’m happy with Python, Node, or Go as long as the solution uses the official Telegram Bot API and runs headless on a small VPS. Scraping or unofficial Instamart endpoints is fine provided captchas, rate limits, and cookies are handled automatically.

Delivery is the working code plus a short README that lets me:

1. Drop my own Telegram bot token
2. List the products to watch
3. Start the bot with one command

Ping me if you need sample product links or want to discuss edge cases.
