+- Search functionality: Implemented in `src/facebook.ts`
+- Individual listing details: Not yet implemented
+
+## Findings
+
+### Step 1: Initial Setup
+- Using Chrome DevTools to inspect Facebook Marketplace
+- Need to authenticate with Facebook account to access marketplace data
+- Cookies required for full access
+- Current status: Successfully logged in and accessed marketplace data
+
+### Step 2: Individual Listing Details Analysis - COMPLETED
+- **Data Location**: Embedded in HTML script tags within `require` array structure
+- **Path**: `require[0][3].__bbox.result.data.viewer.marketplace_product_details_page.target`
+- **Authentication**: Required for full data access
+- **Current Status**: Successfully reverse-engineered the API structure and data extraction method
+
+### API Endpoints Discovered
+
+#### Search Endpoint
+- URL: `https://www.facebook.com/marketplace/{location}/search`
+- Parameters: `query`, `sortBy`, `exact`
+- Data embedded in HTML script tags with `require` structure
+- Authentication: Required (cookies)
+
+#### Listing Details Endpoint
+- **URL Structure**: `https://www.facebook.com/marketplace/item/{listing_id}/`
+- **Data Source**: Server-side rendered HTML with embedded JSON data in script tags

+- **Extraction Method**: Parse JSON from script tags containing marketplace data, navigate to the target object
+- **Authentication**: Required (cookies)
+
+### Listing Data Structure Discovered (Current - 2026)
+
+The current Facebook Marketplace API returns a comprehensive `GroupCommerceProductItem` object with the following key properties:
+
+```typescript

+          formatted_price: { text: string };
+        };
+      };

+
+## Data Extraction Method
+
+### Current Method (2026)
+Facebook Marketplace listing data is embedded in JSON within `<script>` tags in the HTML response. The extraction process:
+
+1. **Find the Correct Script**: Look for script tags containing marketplace listing data by searching for key fields like `marketplace_listing_title`, `redacted_description`, and `formatted_price`.
+
+2. **Parse JSON Structure**: The data is nested within a `require` array structure:
+   ```
+   require[0][3].__bbox.require[3][3][1].__bbox.result.data.viewer.marketplace_product_details_page.target
+   ```
+
+3. **Navigate to Target Object**: The actual listing data is a `GroupCommerceProductItem` object containing comprehensive information about the listing, seller, and vehicle details.
+
+4. **Handle Dynamic Structure**: Facebook may change the exact path, so robust extraction should search for the target object recursively within the parsed JSON.
+
+### Authentication Requirements
+- Valid Facebook session cookies are required
+- User must be logged in to Facebook
+- Marketplace access may be location-restricted
+
+## Tools Used
+- Chrome DevTools Protocol
+- Network monitoring
+- HTML/script parsing
+- JSON structure analysis
+
+## Implementation Status
+- ✅ Successfully reverse-engineered Facebook Marketplace API for listing details
+- ✅ Identified current data structure and extraction method (2026)
+- ✅ Documented comprehensive GroupCommerceProductItem interface
+- ✅ Implemented `extractFacebookItemData()` function with script parsing logic
+- ✅ Implemented `parseFacebookItem()` function to convert GroupCommerceProductItem to ListingDetails
+- ✅ Implemented `fetchFacebookItem()` function with authentication and error handling
+- ✅ Updated TypeScript interfaces to match current API structure
+- ✅ Added robust extraction with fallback methods for changing API paths
+
+## Implementation Details
+
+### Core Functions Implemented
+
+1. **`extractFacebookItemData(htmlString)`**: Extracts marketplace item data from HTML-embedded JSON in script tags
+   - Searches for scripts containing marketplace listing data
+   - Uses primary path: `require[0][3][0].__bbox.require[3][3][1].__bbox.result.data.viewer.marketplace_product_details_page.target`
+   - Falls back to recursive search for GroupCommerceProductItem objects
+
+2. **`parseFacebookItem(item)`**: Converts Facebook's GroupCommerceProductItem to unified ListingDetails format
+   - Handles pricing (FREE listings, CAD currency)
+   - Extracts seller information, location, and status
+   - Supports vehicle-specific metadata
+   - Maps Facebook-specific fields to common interface
+
+3. **`fetchFacebookItem(itemId, cookiesSource?)`**: Fetches individual listing details
+   - Loads Facebook authentication cookies
+   - Makes authenticated HTTP requests
+   - Handles rate limiting and retries
+   - Returns parsed ListingDetails or null on failure
+
+### Authentication Requirements
+- Facebook session cookies required in `./cookies/facebook.json` or provided as parameter
+- Cookies must include valid authentication tokens for marketplace access
+- Handles cookie expiration and domain validation
+
+## Current Implementation Status - 2026 Verification
+
+### Step 3: API Verification and Current Structure Analysis (January 2026)
+- **Verification Date**: January 22, 2026
+- **Status**: Successfully verified current Facebook Marketplace API structure
+- **Data Source**: Embedded JSON in HTML script tags (server-side rendered)
+- **Extraction Path**: `require[0][3].__bbox.require[3][3][1].__bbox.result.data.viewer.marketplace_product_details_page.target`
+
+#### Verified Listing Structure (Real Example - 2006 Hyundai Tiburon)
+- **Listing ID**: 1226468515995685
+- **Title**: "2006 Hyundai Tiburon"
+- **Price**: CA$3,000 (formatted_price.text)
+- **Raw Price Data**: {"amount_with_offset": "300000", "currency": "CAD", "amount": "3000.00"}
+- **Location**: Hamilton, ON (with coordinates: 43.250427246094, -79.963989257812)
+- **Description**: "As is" (redacted_description.text)
+- **Vehicle Details**:
+  - Make: Hyundai
+  - Model: Tiburon
+  - Odometer: 194,000 km
+  - Transmission: AUTOMATIC
+  - Exterior Color: blue
+  - Interior Color: black
+  - Fuel Type: GASOLINE
+  - Number of Owners: TWO
+- **Seller Information**:
+  - Name: Ajitpal Kaler
+  - ID: 100009257293466
+  - Profile Picture Available
+  - Join Time: 1426564800 (2015)
+- **Listing Status**: Active (is_live: true, is_sold: false, is_pending: false)
+- **Category**: 807311116002614 (Vehicles)
+- **Delivery Types**: ["IN_PERSON"]
+- **Messaging**: Enabled
+
+#### Current API Characteristics
+- **Authentication**: Still requires valid Facebook session cookies
+- **Data Format**: Server-side rendered HTML with embedded GraphQL/Relay JSON
+- **Structure Stability**: Primary extraction path remains functional
+- **Additional Features**: Includes marketplace ratings, seller verification badges, cross-posting info
+
+### API Changes Observed Since 2024 Documentation
+- **Minimal Changes**: Core data structure largely unchanged
+- **Enhanced Fields**: Added more detailed vehicle specifications and seller profile information
+- **GraphQL Integration**: Deeper integration with Facebook's GraphQL infrastructure
+- **Security Features**: Additional integrity checks and reporting mechanisms
+
+### Multi-Category Testing Results (January 2026)
+Successfully tested extraction across different listing categories:
+
+#### 1. Vehicle Listings (Automotive)
+- **Example**: 2006 Hyundai Tiburon (ID: 1226468515995685)
+- **Status**: ✅ Fully functional
+- **Data Extracted**: Complete vehicle specs, pricing, seller info, location coordinates
+- **Unique Fields**: vehicle_make_display_name, vehicle_odometer_data, vehicle_transmission_type, vehicle_exterior_color, vehicle_interior_color, vehicle_fuel_type
+
+#### 2. Electronics Listings
+- **Example**: Nintendo Switch (ID: 3903865769914262)
+- **Status**: ✅ Fully functional
+- **Data Extracted**: Title, price (CA$140), location (Toronto, ON), condition (Used - like new), seller (Yitao Hou)
+- **Category**: Electronics (category_id: 479353692612078)
+- **Notes**: Standard GroupCommerceProductItem structure applies
+
+#### 3. Home Goods/Furniture Listings
+- **Example**: Tabletop Mirror (cat not included) (ID: 1082389057290709)
+- **Status**: ✅ Fully functional
+- **Data Extracted**: Title, price (CA$5), location (Mississauga, ON), condition (Used - like new), seller (Rohit Rehan)
+- **Category**: Home Goods (category_id: 1569171756675761)
+- **Notes**: Includes detailed description and delivery options
+
+#### Testing Summary
+- **Extraction Method**: Consistent across all categories
+- **Data Structure**: GroupCommerceProductItem interface works for all listing types
+- **Authentication**: Required for all categories
+- **Rate Limiting**: Standard Facebook rate limits apply
+- **Edge Cases**: All tested listings were active/in-person pickup
+
+## Implementation Status - COMPLETED (January 2026)
+- ✅ Successfully reverse-engineered Facebook Marketplace API for listing details
+- ✅ Verified current API structure and extraction method (January 2026)
+- ✅ Tested extraction across multiple listing categories (vehicles, electronics, home goods)
+- ✅ Implemented comprehensive error handling for sold/removed listings and authentication failures
+- ✅ Enhanced rate limiting and retry logic (already robust)
+- ✅ Added monitoring and metrics for API stability detection
+- ✅ Updated all scraper functions to use verified extraction methods
+- ✅ Documented comprehensive GroupCommerceProductItem interface with real examples
+
+## Next Steps (Future Maintenance)
+1. Monitor extraction success rates for API change detection
+2. Update extraction paths if Facebook changes their API structure
+3. Add support for additional marketplace features as they become available
+4. Implement caching mechanisms for improved performance
+5. Add support for marketplace messaging and negotiation features
