Find and share AliExpress affiliate products through Telegram

Build a Telegram bot that helps users find AliExpress products using natural language requests. The bot uses OpenAI to optimize search queries, Decodo to scrape product listings, and AI analysis to select the best options based on ratings, reviews, and price—then automatically generates affiliate tracking links for each recommendation.

What it does

When users send "Find me wireless keyboard":

1. Bot checks user is member of your Telegram channel (optional)
2. Validates command starts with accepted phrases
3. OpenAI generates optimized English search query
4. Decodo scrapes products from AliExpress
5. AI analyzes the top 10 products and selects best 2 based on reviews, ratings, and price
6. AliExpress Affiliate API creates tracking links
7. Bot sends formatted recommendations with images, prices, ratings, and links

• E-commerce entrepreneurs automating recommendations
