🎨 Client Integration

JavaScript/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();

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

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 

// 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 

// 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 

// 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"
);

  • crypto_resources_unified.json - Registry metadata

Update Frequency

  • Resources are cached in memory on first load
  • No disk I/O after initial load
  • Restart server to reload from files

Adding New Resources

To add new resources to the database:

  1. Update the JSON files in api-resources/
  2. Follow the schema format
  3. Restart the server
  4. Resources will be automatically loaded

🎯 Performance Characteristics

  • Initial Load: ~200ms (loads both JSON files)
  • Cached Queries: <1ms (in-memory)
  • Search: ~5-10ms (linear search through 436 resources)
  • Category Filtering: <2ms (dictionary lookup)
  • Random Selection: <3ms (random sampling)

📊 Resource Quality Metrics

Unified Database

  • ✅ Structured: All resources follow consistent schema
  • ✅ Documented: Includes notes, docs URLs, and metadata
  • ✅ Categorized: 13 well-defined categories
  • ✅ Auth Info: Clear authentication requirements

Pipeline Database

  • ✅ TypeScript Examples: Working code samples included
  • ✅ Rate Limits: Documented for each resource
  • ✅ Free/Paid: Clear indicators
  • ✅ Multi-category: 11 diverse categories

🚀 Future Enhancements

Planned Features

  1. Health Monitoring: Check resource availability
  2. Rate Limit Tracking: Monitor usage across resources
  3. Auto-Fallback: Automatic failover between similar resources
  4. Resource Testing: Automated endpoint validation
  5. Usage Analytics: Track which resources are most used
  6. Community Ratings: User feedback on resource quality

Database Expansion

  • Add more blockchain networks
  • Include Layer 2 solutions
  • Add more DeFi protocols
  • Expand NFT marketplace coverage
