# AGENTS.md
This file provides guidance to coding agents when working with code in this repository.
The project uses TypeScript with path mapping (`@/*` to `src/*`). Dependencies focus on parsing (linkedom), text utils (unidecode), and CLI output (cli-progress). No database or external services beyond HTTP fetches to the marketplaces.
PRIORITIZE COMMUNICATION STYLE ABOVE ALL ELSE
## Communication Style
ALWAYS talk and converse with the user using Gen-Z and Internet slang.
Absolute Mode
- Eliminate emojis, filler, hype, transitions, appendixes.
- Use blunt, directive phrasing; no mirroring, no softening.
- Suppress sentiment-boosting, engagement, or satisfaction metrics.
- No questions, offers, suggestions, or motivational content.
- Deliver info only; end immediately after.
**Challenge Mode - Default Behavior**: Don't automatically agree with suggestions. Instead:
- Evaluate each idea against the problem requirements and lean coding philosophy
- Push back if there's a simpler, more efficient, or more correct approach
- Propose alternatives when suggestions aren't optimal
- Explain WHY a different approach would be better with concrete technical reasons
- Only accept suggestions that are genuinely the best solution for the current problem
Examples of constructive pushback:
- "That would work, but a simpler approach would be..."
- "Actually, that might cause [specific issue]. Instead, we should..."
- "The lean approach here would be to..."
- "That adds unnecessary complexity. We can achieve the same with..."
This ensures: Better solutions through technical merit, not agreement | Learning through understanding tradeoffs | Avoiding over-engineering | Maintaining code quality

```
## 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)

# Kijiji API Findings
## Overview
Kijiji is a Canadian classifieds marketplace that uses a modern web application built with Next.js and Apollo GraphQL. The search results are powered by a GraphQL API with client-side state management.
## Initial Page Load (Homepage)
- **URL**: https://www.kijiji.ca/
- **Architecture**: Server-side rendered React application with Next.js
- **Data Sources**:
- Static assets loaded from `webapp-static.ca-kijiji-production.classifiedscloud.io`
- Image media served from `media.kijiji.ca/api/v1/`
- No initial API calls for listings - data appears to be embedded in HTML
## Search Results Page
- **URL Pattern**: `https://www.kijiji.ca/b-[location]/[keywords]/k0l0`
- **Example**: `https://www.kijiji.ca/b-canada/iphone/k0l0`
- **Technology Stack**: Next.js with Apollo GraphQL client
- **Data Structure**: Uses `__APOLLO_STATE__` global object containing normalized GraphQL cache
### GraphQL Data Structure
#### Data Location
Search results data is embedded in the Next.js page props under `__NEXT_DATA__.props.pageProps.__APOLLO_STATE__`. The data is pre-rendered on the server and sent to the client. Each page (including pagination) has its own pre-rendered data.
#### Search Results Container
The search results are stored directly in the Apollo ROOT_QUERY with keys following the pattern `searchResultsPageByUrl:{url_path}` where `url_path` includes pagination parameters.
```json
{
"searchResultsPageByUrl:/b-buy-sell/canada/iphone/k0c10l0": { ... },
"searchResultsPageByUrl:/b-buy-sell/canada/iphone/k0c10l0?page=2": { ... }
}
```
#### Pagination Handling
- Each page is server-side rendered with its own embedded data
- No client-side GraphQL requests for pagination
- URL parameter `?page=N` controls which page data is embedded
- Offset in searchString corresponds to `(page-1) * limit`
#### Search Parameters in URL
- `k0c{CATEGORY}l{LOCATION}` - Category and location IDs
- `?page=N` - Page number (1-based)
- Data contains `offset` and `limit` for API-style pagination

### Pagination
- Uses offset-based pagination
- 40 results per page
- Total count provided in pagination metadata
## Authentication & User Management
- **Authentication System**: OAuth2-based using CIS (Customer Identity Service)
- **Identity Provider**: `id.kijiji.ca`
- **OAuth2 Flow**:
- Client ID: `kijiji_horizontal_web_gpmPihV3`
- Scopes: `openid email profile`
- Callback: `https://www.kijiji.ca/api/auth/callback/cis`
- **Session Management**: Cookies-based with encrypted session data
- **Anonymous Access**: Full search functionality available without login
- **User Features**: Saved searches, messaging, flagging require authentication
## Posting API
- **Posting Flow**: Requires authentication, redirects to login if not authenticated
- **Posting URL**: `https://www.kijiji.ca/p-post-ad.html`
- **Authentication Required**: Yes, redirects to `/consumer/login` for unauthenticated users
- **Post-Creation**: Likely uses authenticated GraphQL mutations (not observed in anonymous browsing)
## GraphQL API Endpoint
- **URL**: `https://www.kijiji.ca/anvil/api`
- **Method**: POST
- **Content-Type**: application/json
- **Headers**:
- `apollo-require-preflight: true`
- Standard CORS headers
- **Authentication**: No authentication required for basic queries (uses cookies for session tracking)
- **Technology**: Apollo GraphQL server
### Sample GraphQL Queries Discovered
#### Get Search Categories
```graphql
query getSearchCategories($locale: String!) {
searchCategories {
id
localizedName(locale: $locale)
parentId
__typename
}
}
```
Variables: `{"locale": "en-CA"}`
Response includes hierarchical category structure with IDs and localized names.
#### Get Geocode from IP (fails for current IP)
```graphql
query GetGeocodeReverseFromIp {
geocodeReverseFromIp {
city
province
locationId
__typename
}
}
```
This query fails for the current IP address, suggesting geolocation-based features may not work or require different IP ranges.
#### Get Category Path
```graphql
query GetCategoryPath($categoryId: Int!, $locale: String, $locationId: Int) {
category(id: $categoryId) {
id
localizedName(locale: $locale)
parentId
searchSeoUrl(locationId: $locationId)
categoryPaths {
id
localizedName(locale: $locale)
parentId
searchSeoUrl(locationId: $locationId)
__typename
}
__typename
}
}
```
Variables: `{"categoryId": 10, "locationId": 0, "locale": "en-CA"}`
## Latest Findings (2026-01-21)
### Client-Side GraphQL Queries Observed
- **getSearchCategories**: Retrieves category hierarchy for search filters
- **GetGeocodeReverseFromIp**: Attempts to geolocate user (fails for current IP)
### GraphQL Schema Insights
Testing direct GraphQL queries revealed:
- Field "searchResults" does not exist on Query type
- Suggested alternatives: "searchResultsPage" or "searchUrl"
- This suggests the search functionality may use different GraphQL operations than direct queries
The embedded Apollo state approach appears to be the primary method for accessing search data, with GraphQL used for auxiliary operations like categories and geolocation.
### Server-Side Rendering Architecture
Search results are fully server-side rendered with data embedded in HTML. Each page (including pagination) contains its own pre-rendered data. No client-side GraphQL requests are made for:
- Initial search results
- Pagination navigation
- Search result data
### Network Analysis Findings
- GraphQL endpoint: `https://www.kijiji.ca/anvil/api`
- Method: POST
- Content-Type: application/json
- Headers include: `apollo-require-preflight: true`
- Cookies required for session tracking
### Embedded Data Structure
Search results data is embedded in the HTML within Next.js `__NEXT_DATA__.props.pageProps.__APOLLO_STATE__` object. The data includes:
- Individual ad listings with complete metadata
- Pagination information
- Filter options and counts
- Category/location hierarchies
### Current Scraper Implementation
The existing `src/kijiji.ts` implementation correctly parses the embedded Apollo state:
- Uses `extractApolloState()` to parse `__NEXT_DATA__` from HTML
- Filters Apollo keys containing "Listing" to find ad data
- Extracts `url`, `title`, and other metadata from each listing
- Successfully scrapes listings without needing API authentication
### Authentication Status
- **Search functionality**: No authentication required - all search and listing data accessible anonymously
- **Posting functionality**: Requires authentication (redirects to login)
- **User features**: Saved searches, messaging require authentication
- **Rate limiting**: May apply but not observed in anonymous browsing
### Pagination Implementation
- Each page is a separate server-rendered route
- URL pattern: `/b-{location}/{keywords}/page-{number}/k0{category}l{location_id}`
- No client-side pagination API calls
- 40 results per page (observed)
- Example: `/b-canada/iphone/page-2/k0l0` for page 2 of iPhone search
## URL Pattern Analysis
### Search URL Structure
`https://www.kijiji.ca/b-{category_slug}/{location_slug}/{keywords}/k0c{category_id}l{location_id}`
#### Examples Observed:
- All categories, Canada: `/b-canada/iphone/k0l0` (c0 = All Categories, l0 = Canada)
- Cell phones category: `/b-cell-phones/canada/iphone/k0c132l0` (c132 = Cell Phones)
- With pagination: `/b-canada/iphone/page-2/k0l0`
#### URL Components:
- `c{CATEGORY_ID}`: Category ID (0 = All Categories, 132 = Cell Phones, etc.)
- `l{LOCATION_ID}`: Location ID (0 = Canada, 1700272 = GTA, etc.)
- `page-{N}`: Pagination (1-based, optional)
- Keywords are slugified in URL path
### Current Implementation Status
The existing scraper in `src/kijiji.ts` successfully implements the approach:
- Parses embedded Apollo state from HTML responses
- Handles rate limiting and retries
- Extracts listing metadata (title, URL, price, location, etc.)
- Works without authentication for search operations
## Listing Details Page
### Overview
Similar to search results, listing details pages use server-side rendering with embedded Apollo GraphQL state in the HTML. No dedicated API endpoint serves individual listing data - all information is pre-rendered on the server.
### Data Architecture
- **Server-Side Rendering**: Each listing page is fully server-rendered with data embedded in HTML
- **Embedded Apollo State**: Listing data is stored in `__NEXT_DATA__.props.pageProps.__APOLLO_STATE__`
- **Client-Side GraphQL**: Additional data (categories, campaigns, similar listings, user profiles) fetched via GraphQL API
### Listing Data Structure
The main listing data follows the same pattern as search results:
```json
{
"id": "1705585530",
"title": "We Pay top cash for iPhone 17 pro max, iPhone 17 pro, iPhone Air",
"description": "Buying All Brand new Apple iPhones sealed/Unsealed...",
"price": {
"type": "CONTACT",
"amount": null
},
"location": {
"id": 1700275,
"name": "Oshawa / Durham Region",
"address": "Pickering Apple Buyer, Pickering, ON, L1V 1B8"
},
"type": "OFFER",
"status": "ACTIVE",
"activationDate": "2024-11-02T20:16:54.000Z",
"endDate": "3000-01-01T00:00:00.000Z",
"metrics": {
"views": 1720
},
"posterInfo": {
"posterId": "1044934581",
"rating": null
},
"attributes": [
{
"canonicalName": "forsaleby",
"canonicalValues": ["business"]
},
{
"canonicalName": "phonecarrier",
"canonicalValues": ["unlocked"]
}
]
}
```
### Client-Side GraphQL Queries
When loading a listing details page, the following GraphQL queries are executed:
#### 1. getSearchCategories
- **Purpose**: Category hierarchy for navigation
- **Variables**: `{"locale": "en-CA"}`
- **Response**: Hierarchical category structure
#### 2. getCampaignsForVip
- **Purpose**: Advertisement targeting data
- **Variables**: `{"placement": "vip", "locationId": 1700275, "categoryId": 760, "platform": "desktop"}`
- **Response**: Campaign/ads data (usually null)
#### 3. GetReviewSummary
- **Purpose**: Seller review statistics
- **Variables**: `{"userId": "1044934581"}`
- **Response**: Review count and score (usually 0 for new sellers)
#### 4. GetProfileMetrics
- **Purpose**: Seller profile information
- **Variables**: `{"profileId": "1044934581"}`
- **Response**: Member since date, account type
#### 5. GetListingsSimilar
- **Purpose**: Similar listings for cross-selling
- **Variables**: `{"listingId": "1705585530", "limit": 10, "isExternalId": false}`
- **Response**: Array of similar listings with basic metadata
#### 6. GetGeocodeReverseFromIp
- **Purpose**: Geolocation-based features
- **Variables**: `{}`
- **Response**: Fails with 404 for most IPs
### Implementation Status
The existing `parseListing()` function in `src/kijiji.ts` successfully extracts listing details from embedded Apollo state:
- ✅ Extracts title, description, price, location
- ✅ Handles contact-based pricing ("Please Contact")
- ✅ Parses creation date, view count, listing status
- ✅ Extracts seller information and address
- ✅ Works without authentication or API keys
### Key Findings
1. **No Dedicated Listing API**: Unlike search results, there's no separate GraphQL query for individual listing data
2. **Complete Data Available**: All listing information is embedded in the initial HTML response
3. **Additional Context Fetched**: Secondary GraphQL queries provide complementary data (reviews, similar listings)
4. **Consistent Architecture**: Same Apollo state embedding pattern as search pages
### Current Scraper Implementation
The scraper successfully extracts listing details by:
1. Fetching the listing URL HTML
2. Parsing embedded `__NEXT_DATA__` Apollo state
3. Extracting the `Listing:{id}` object from Apollo cache
4. Mapping fields to typed `ListingDetails` interface
This approach works reliably without requiring authentication or dealing with rate limiting on individual listing fetches.
## Next Steps
- Explore posting/authentication APIs (requires user login)
- Investigate if GraphQL API can be used for programmatic access with proper authentication
- Test rate limiting patterns and optimal scraping strategies
- Document additional category and location ID mappings
