eBay Deep Scan Dashboard

A professional eBay scanning and price monitoring tool. It automates searching for products across international eBay marketplaces, filters for the best deals based on target prices, and uses AI to verify product authenticity and seller reputation.

🚀 Key Features

• Profile Management: Create and manage different scan profiles (e.g., RAM, SSD, CPUs) with individual target prices and price ratios.
• International Search: Automatically scans eBay US, UK, AU, CA, and DE marketplaces.
• Smart Filtering:
  • Skips Group Products (multi-variation listings) that lack deterministic logic.
  • Filters out defective/broken items and listings from China (CN).
  • Advanced Quantity Extraction: Intelligently parses quantities (e.g., 4x256GB, Lot of 10) while avoiding technical specs (e.g., NVMe x4, PCIe x16).
• AI-Powered Analysis: Uses OpenAI GPT-4o-mini to analyze listings for "fake" red flags, seller credibility, and technical spec matches.
• Real-time Dashboard:
  • Progress Bar: Monitor scan progress in real-time.
  • Enriched Details: View high-res images, full descriptions, and calculated profit margins.
  • Usage Tracking: Summarizes total "Quote Requests" and AI tokens consumed at the end of each process.
• Persistence: Powered by SQLite for reliable data storage of profiles, keywords, and found items.
