participant Chain as Blockchain
participant Escrow as Payment Escrow
Agent->>Market: Discover services (category, price, rating)
Market-->>Agent: Return matching services
Agent->>Market: Subscribe to service
Market->>Chain: Create subscription
Agent->>Escrow: Send payment (USDC)
Escrow-->>Service: Payment held in escrow

### Key Components
#### 1. Service Registry (On-Chain)
```solidity
struct Service {
address owner;
string endpoint;
uint256 payPerUsePrice;
uint256 monthlyPrice;
uint256 rating; // Weighted average
uint32 reviewCount;
bool active;
}
```
#### 2. Reputation System (On-Chain)
```solidity
struct Rating {
address reviewer;
uint8 stars; // 1-5
string review;
bool verified; // Paid customer
}
```
#### 3. Subscription Management (On-Chain)
```solidity
struct Subscription {
address subscriber;
uint256 expiresAt;
bool autoRenew;
uint256 renewalCount;
}
```
#### 4. Payment Escrow (On-Chain)
- Holds payments until service delivered
- Automatic release after period
- Refunds for disputes

## 🌟 Reputation System
### How Ratings Work
1. **User subscribes/pays** for service
2. **Uses the service** (API calls)
3. **Leaves a rating** (1-5 stars + review)
4. **Rating recorded on-chain** with verification
5. **Service rating updated** (weighted average)
### Rating Weight
```typescript
// Verified customers (paid) have 2x weight
const weight = rating.verified ? 2 : 1;
const newRating = (oldRating * oldCount + stars * 100 * weight) / (oldCount + weight);
```
### Review Quality
- **Verified badge** for paying customers
- **Helpful votes** for quality reviews
- **Spam reporting** for fake reviews
- **Response from owner** for all reviews
