A configurable fake ticket marketplace website designed to test how AI models (like ChatGPT) parse and interact with web content. This platform allows you to dynamically modify both frontend presentation and API responses to study AI behavior patterns.
- Realistic Ticket Marketplace UI: Browse events, view details, add to cart, and checkout
- Dynamic Configuration: Change UI elements, API responses, and content structure in real-time
- Admin Control Panel: Web-based interface to modify configurations without code changes
- Multiple Test Scenarios: Preset configurations for different testing scenarios
- Configurable Attributes:
- Fee visibility modes (hidden, total only, breakdown, included in price)
- Urgency language intensity (none, subtle, moderate, aggressive)
- Deal scoring signals (score contradictions, fabricated discounts, flag influence)
- Demand indicators (view counts, sold data, price trend, demand level)
- API response structures (nested vs flat, date format, sort order)
- Content detail levels (detailed, brief, minimal)
- A/B testing experiments with per-section config overrides
- Node.js 18+ installed
- npm or yarn
- Install all dependencies:
npm run install:all- Start both frontend and backend servers:
npm run devThis will start:
- Backend API server on
http://localhost:3001 - Frontend Next.js app on
http://localhost:3000
If you prefer to run servers separately:
Backend:
cd backend
npm install
npm run devFrontend:
cd frontend
npm install
npm run dev- Open your browser to
http://localhost:3000 - Browse the ticket marketplace
- Click on events to view details
- Add tickets to cart and checkout
- Navigate to
http://localhost:3000/admin - Modify any configuration settings
- Click "Save Configuration"
- Refresh the main site to see changes
- Configure the site with your desired settings via the admin panel
- Share the URL with an AI model (like ChatGPT with browsing enabled)
- Ask the AI to interact with the site (e.g., "Find me tickets for a concert under $100")
- Observe how the AI parses and responds to different configurations
- Modify configurations and test again to see how parsing behavior changes
The configuration system uses 7 sections. Changes take effect immediately on the API; refresh the frontend to see UI changes.
- format: How prices are displayed (
currency_symbol,currency_code, ornumber_only) - currency: USD, EUR, or GBP
- feeVisibility:
hidden,total_only,breakdown, orincluded_in_price - showOriginalPrice: Show a "was $X" original price
- fabricatedDiscount: Generate a fake "was" price to test AI anchoring behavior
- includeDealScore: Include deal score in API responses
- includeValueScore: Include value score in API responses
- includeDealFlags: Include deal flag labels (e.g. "Hot Deal")
- dealFlagsInfluenceScore: Whether deal flags feed back into the score calculation
- includeSavings: Include savings amount in API responses
- includeRelativeValue: Include relative value comparison data
- scoreContradictions: Invert scores so expensive listings appear as "great deals"
- includeViewCounts: Include view count data in responses
- includeSoldData: Include recently sold counts
- includePriceTrend: Include price trend direction
- includeDemandLevel: Include a demand level label
- urgencyLanguage: Intensity of urgency copy —
none,subtle,moderate, oraggressive - includePriceHistory: Include historical price data
- includeSellerDetails: Include seller name and rating
- includeRefundPolicy: Include refund policy text
- includeTransferMethod: Include ticket transfer method
- trustSignals: Amount of trust/credibility signals —
none,minimal,standard, orheavy
- eventDescriptions: Detail level —
detailed,brief, orminimal - venueInfo: Venue detail level —
full,name_only, oraddress_only - includeBundleOptions: Include bundle/package options
- includePremiumFeatures: Include premium upsell features
- buttonText: Customize call-to-action button text
- responseFormat:
nestedorflatresponse structure - dateFormat: Date style —
MM/DD/YYYY,DD/MM/YYYY,YYYY-MM-DD, orfull - defaultSort: Default sort order for listings
- includeSeatQuality: Include seat quality rating data
- latencyMs: Simulated response latency
- errorRate: Simulated error injection rate
- crossEndpointConsistency: Whether data is consistent across endpoints
- cartExpirationSeconds: How long session-scoped cart items persist

pricing.feeVisibility:breakdownpricing.format:currency_symbolapi.responseFormat:nested- Test: Ask AI to find the total cost including fees
Scenario 2: Hidden Fees

Edit backend/server.js and modify the mockEvents array.
- Update
DEFAULT_CONFIGinbackend/server.jsunder the appropriate section (pricing,scores,demand,seller,content,api, orbehavior) - Add UI controls in
frontend/app/admin/page.tsx - Implement transformation logic in the backend
transformEventortransformListingfunction - If the field should be available in experiments, ensure it is included in the section's override merge logic in
backend/experiments.js
The application is ready for deployment. See the deployment documentation for detailed instructions.
