## 💼 Use Cases
### 1. Weather API Service
**Problem:** AI agents need weather data
**Solution:** Register weather API, earn $0.001 per request
**Revenue:** 10,000 requests/day = $300/month
### 2. Trading Signal Bot
**Problem:** Traders want AI-powered signals
**Solution:** Subscription-based signal service
**Revenue:** 100 subscribers × $49.99 = $5,000/month
### 3. AI Image Generation
**Problem:** Apps need AI-generated images
**Solution:** Tiered pricing by resolution
**Revenue:** 1,000 images/day × $0.05 = $1,500/month
### 4. Data Analytics API
**Problem:** DeFi projects need analytics
**Solution:** Pay-per-query with volume discounts
**Revenue:** 50 pro users × $99.99 = $5,000/month

## 🚀 How to Use
### For Service Providers
**1. Register Service:**
```typescript
import { MarketplaceService } from '@nirholas/universal-crypto-mcp-marketplace';
const marketplace = new MarketplaceService({
chain: 'arbitrum',
privateKey: process.env.PRIVATE_KEY
});
await marketplace.registerService({
name: 'Weather AI',
description: 'AI-powered weather forecasting',
category: 'weather',
endpoint: 'https://api.example.com',
pricing: {
payPerUse: '$0.001',
subscription: { monthly: '$9.99' }
},
walletAddress: '0x...'
});
```
**2. Verify Payments:**
```typescript
import { SubscriptionManager } from '@nirholas/universal-crypto-mcp-marketplace';
const manager = new SubscriptionManager({
contractAddress: '0x...',
tokenAddress: '0x...',
chain: 'arbitrum'
});
// Check if user has active subscription
const isActive = await manager.isActive(serviceId, userAddress);
```
**3. Track Analytics:**
```typescript
const analytics = await marketplace.getAnalytics(serviceId, 'month');
console.log(`Revenue: $${analytics.revenue}`);
```
### For Service Consumers
**1. Discover Services:**
```typescript
const services = await marketplace.discoverServices({
category: 'weather',
maxPrice: '$0.01',
minRating: 4.5,
sortBy: 'rating'
});
```
**2. Subscribe:**
```typescript
await marketplace.subscribe({
serviceId: services[0].id,
plan: 'monthly',
paymentToken: 'USDC',
autoRenew: true
});
```
**3. Rate Service:**
```typescript
await marketplace.rateService({
serviceId: services[0].id,
rating: 5,
review: 'Excellent service!'
});
```
