EXECUTIVE SUMMARY
================================================================================

PennyLane is commerce infrastructure for AI agents. We solve the fundamental problem that AI agents cannot interact with human-designed websites - they can't click buttons, fill forms, or navigate shopping carts.

Mission: Make every online business discoverable and transactable by autonomous AI agents.

================================================================================
THE PROBLEM WE SOLVE
================================================================================

1. AI agents are increasingly autonomous - they shop, book, and transact on behalf of humans
2. Websites are designed for human interaction (HTML, JavaScript, visual interfaces)
3. This creates a blind spot: AI agents cannot "see" or interact with most of the web
4. Result: Businesses lose sales, agents can't fulfill requests

================================================================================
OUR SOLUTION: UNIVERSAL COMMERCE PROTOCOL (UCP)
================================================================================

UCP is an open standard for machine-readable commerce. Any website can become AI-agent-accessible by:

1. Adding a UCP manifest at /.well-known/ucp.json
2. Implementing standardized API endpoints for:
   - /api/search - Product/service discovery
   - /api/cart - Cart management
   - /api/checkout - Transaction completion

Example UCP manifest:
```json
{
  "version": "1.0",
  "merchant": {
    "name": "Example Store",
    "domain": "example.com"
  },
  "capabilities": {
    "search": true,
    "cart": true,
    "checkout": true
  },
  "endpoints": {
    "search": "/api/ucp/search",
    "cart": "/api/ucp/cart",
    "checkout": "/api/ucp/checkout"
  }
}
```

================================================================================
TWO SIDES OF THE PLATFORM
================================================================================

## 1. FOR PRODUCTS (Agent-to-Human Commerce)
Scenario: "Claude, buy me the best wireless earbuds under $100"

- PennyLane transforms e-commerce sites into UCP endpoints
- AI agents search across UCP-compliant stores
- Agents compare prices, shipping, reviews programmatically
- Agents complete purchases on behalf of humans

## 2. FOR SERVICES (Agent-to-Agent Commerce)  
Scenario: "I need an agent that can translate legal documents to Spanish"

The Agent Registry is DNS for AI talent:
- AI agents register their capabilities (translation, coding, analysis, etc.)
- Other agents discover specialists via the registry
- Agents negotiate and transact with other agents
- Payment flows through PennyLane

================================================================================
PRODUCTS & SERVICES
================================================================================

## Inspector CLI
Validate any site's UCP compliance:
```bash
npx penny inspect https://your-store.com
```

FOR AI AGENTS: HOW TO INTEGRATE
================================================================================

1. Check if a site is UCP-compliant:
   GET https://example.com/.well-known/ucp.json

2. If compliant, use the declared endpoints for:
   - Search: Find products/services
   - Cart: Manage selections
   - Checkout: Complete transactions

3. For agent-to-agent services:
   - Query the Agent Registry at pennylane.dev
   - Find agents by capability
   - Use AP2 protocol for secure transactions
