+// Get random resources for discovery
+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"
+);
+```

+
+## 🎨 Use Cases Enabled
+
+### 1. Multi-Source Fallback Strategy
+Build robust applications with automatic failover:
+```javascript
+// Get all RPC nodes for fallback
+const rpcs = await fetch('/api/resources/database/category/rpc_nodes');
+const nodes = await rpcs.json();
+
+// Try each node until one works
+for (const node of nodes.unified_resources.resources) {
+  try {
+    const result = await callRPC(node.base_url);
+    if (result) break;
+  } catch {
+    continue; // Try next node
+  }
+}
+```
+
+### 2. Resource Discovery Dashboard
+Allow users to explore available data sources:
+```javascript
+// Show random resources for discovery
+setInterval(async () => {
+  const random = await fetch('/api/resources/database/random?count=5');
+  const resources = await random.json();
+  displayResources(resources.resources);
+}, 10000);
+```
+
+### 3. API Directory/Catalog
+Build a searchable directory of crypto APIs:
+```javascript
+// Search and display results
+const search = await fetch(
+  `/api/resources/database/search?q=${query}&limit=50`
+);
+const results = await search.json();
+renderSearchResults(results.results);
+```
+
+### 4. Smart Resource Selection
+Choose the best resource based on criteria:
+```javascript
+const market = await fetch('/api/resources/database/category/market_data_apis');
+const apis = await market.json();
+
+// Filter for free APIs with high rate limits
+const best = apis.unified_resources.resources
+  .filter(api => api.auth.type === 'none')
+  .sort((a, b) => getRateLimit(b) - getRateLimit(a))[0];
+```
