## 🎨 Client Integration

### JavaScript/TypeScript
```typescript
// Get all resources
const response = await fetch('/api/resources/database?source=all');
const data = await response.json();

// Search resources
const searchResults = await fetch('/api/resources/database/search?q=coingecko');
const found = await searchResults.json();

const random = await fetch('/api/resources/database/random?count=10');
const randomResources = await random.json();
```

### Python
```python
import requests

# Get database stats
stats = requests.get('https://your-api.hf.space/api/resources/database/stats')
print(f"Total resources: {stats.json()['overview']['total_resources']}")

# Search for Binance resources
search = requests.get(
    'https://your-api.hf.space/api/resources/database/search',
    params={'q': 'binance', 'limit': 10}
)
print(search.json())
```

---

## 🔧 Advanced Use Cases

### 1. Build a Resource Directory UI
```javascript
// Fetch all categories
const categories = await fetch('/api/resources/database/categories');
const cats = await categories.json();

// For each category, fetch resources
for (const category of cats.unified_resources.categories) {
  const resources = await fetch(
    `/api/resources/database/category/${category}?limit=100`
  );
  // Display in UI
}
```

### 2. Resource Discovery Dashboard
```javascript
// Get random resources every 5 seconds for discovery
setInterval(async () => {
  const random = await fetch('/api/resources/database/random?count=3');
  const resources = await random.json();
  displayResources(resources.resources);
}, 5000);
```

### 3. Smart Resource Selection
```javascript
// Find best resource for a specific use case
const search = await fetch(
  '/api/resources/database/search?q=price&fields=name,desc&limit=50'
);
const results = await search.json();

// Filter by criteria
const freeAPIs = results.results.filter(r => 
  r.resource.free === true || 
  r.resource.auth?.type === "none"
);
```
