Python eBay Price Tracker Development

Job ID: 39603522

Budget: $750 – $1,500 USD

Build Python eBay Price Tracker + GPT Integration for Smart Product Comparison (No Chat UI)

Project Description:
I’m looking for a skilled Python developer to build an application that tracks eBay listings for specific products, compares prices to calculated market averages, and identifies listings that are significantly underpriced.
In addition, the system should leverage ChatGPT (OpenAI API) in the backend not for user interaction, but for:
• Standardizing and matching product names (e.g., handling inconsistent or vague listing titles)
• Comparing similar listings across platforms
• Improving accuracy in identifying deals
The end goal is a system that quietly runs in the background, evaluates listings intelligently, and flags high-value opportunities for users or for further automation.

Requirements:
1. eBay Integration
• Use eBay Finding or Browse API to fetch live listings
• Filter by keyword, condition, price, etc.
2. Price Analysis Engine
• Calculate average, median, and historical trends
• Identify listings under a defined threshold (e.g. 20% below average)
3. GPT Integration (No Chat UI)
• Use OpenAI’s GPT API to:
o Normalize product titles
o Compare listing descriptions to standard product templates
o Identify similar items even if described differently
4. Notification System (Optional)
• Email or SMS alerts for selected deals (SendGrid, Twilio, etc.)
5. (Optional but Nice to Have)
• Small dashboard or simple REST API for triggering scans and checking results

Preferred Tech Stack:
• Python 3.x
• eBay API
• OpenAI API (GPT-4)
• Flask or FastAPI (optional REST interface)
• SQLite / MongoDB
• Optional: SendGrid, Twilio, Firebase

Deliverables:
• Fully working script or app with clear instructions
• GPT-enabled product matching and comparison logic
• Sample input/output with pricing logic
• Optional: hosted endpoint or local interface

Timeline:
Delivery expected within 10–14 days

Budget:
Open to reasonable fixed-price or hourly offers. Please include:
• Estimated timeline
• Proposed approach to GPT-based product normalization
• Relevant experience or sample projects

To Apply:
Please share:
• Your experience with eBay APIs, OpenAI, and price tracking
• Tools you’d use for product comparison logic
• Any similar automation, AI, or price intelligence projects you’ve worked on
