How Does BidWiser Work?

BidWiser uses artificial intelligence to analyze eBay listings and provide you with safety insights before you bid.

The Analysis Process

Step 1: Data Collection

When you submit a listing for analysis, we fetch data from eBay using 5 different API calls:

• GetItem - Full item details including description, condition, photos, and seller info
• GetUser - Detailed seller profile, registration date, and verification status
• GetFeedback - Recent negative and neutral feedback with seller responses
• GetItemShipping - Shipping costs and options for your location
• GetStore - Seller's eBay store information (if applicable)

Step 2: AI Analysis

All this data is sent to our AI engine (ChatGPT 4o-mini with custom prompts) which:

• Evaluates seller trustworthiness based on history and feedback patterns
• Assesses listing quality including description, photos, and pricing
• Identifies potential red flags and concerns
• Recognizes positive trust indicators

Step 3: Score Generation

The AI generates three reliability scores (0-100):

• Seller Score - How trustworthy is this seller?
• Listing Score - How well-presented and legitimate is this listing?
• Overall Score - Combined assessment of the transaction

Step 4: Results Display

Your analysis report shows:

• The three scores with color coding (green/yellow/red)
• Positive indicators (green checkmarks)
• Cautions to consider (yellow warnings)
• Red flags to be aware of (red alerts)
• A summary paragraph explaining the key findings

Caching

Results are cached for 10 days. This means:

• Viewing the same item again is instant
• It doesn't count toward your monthly quota
• You can share the analysis link with others

The AI Model

We use ChatGPT 4o-mini with carefully crafted prompts designed specifically for eBay listing analysis. Our prompts are tuned to:

• Be generous with good sellers (not overly suspicious)
• Flag real concerns (not trivial matters)
• Provide actionable insights
• Quote specific feedback when relevant
