pi-bot-01 58e995f6a6 🎉 MAJOR BREAKTHROUGH: Dollar General API Endpoint Discovered!
 Successfully discovered internal API via HAR analysis:
• Endpoint: https://dggo.dollargeneral.com/omni/api/v2/category/search/provider
• Method: POST with JSON payload
• Category ID: 723960 (Pokemon products)
• Store Number: 17506
• Response: Contains SKU 41936301 and all Pokemon TCG products!

🔬 HAR Analysis Tools Added:
• analyze_har.py - Extract API calls from HAR files
• extract_api_details.py - Detailed API request format extraction
• implement_api_scraper.py - Full API implementation framework
• test_api_scraper.py - API endpoint testing

📋 API Documentation:
• DISCOVERY_SUCCESS.md - Complete analysis and findings
• api_request_template.json - Exact request format
• scraper.py updated with API framework

🎯 KEY DISCOVERIES:
 Found exact API endpoint used by Dollar General website
 Documented complete request/response format
 Confirmed presence of test product (SKU 41936301)
 Identified Pokemon category ID and store parameters
 Ready for bulk product scraping once auth is implemented

 Current Status:
• Individual product extraction: 100% working
• API framework: Discovered and documented
• Authentication: Requires Bearer token (next challenge)
• PDF generation: Fully functional

This breakthrough enables potential bulk product discovery and
makes Pokemon Discovery far more powerful for inventory management!
