sarakmacbook/OKX_Telegram_P2P_Price_Bot ? reverse-engineered prompt

Build me a Telegram bot that watches P2P merchant prices on Binance, Bybit, OKX, and Bitget, then posts the best buy and sell prices into a Telegram group whenever they change.

I want it to be easy to run in a few different ways, ideally with a simple setup script for a VPS, a Docker option, a local run option for laptops or WSL, and a serverless option for Vercel with a small web setup page and webhook support. It should ask for the bot token and my Telegram ID, let me choose a merchant or paste a merchant URL, and then keep sending price updates automatically. Please include a basic admin flow in Telegram so I can start it, set the group, and turn auto updates on or off.

If you need current API details or deployment docs, look them up online and make the setup reliable.
