Best Practices

Cache API responses to reduce requests:
• Latest rates: Cache for 1-5 minutes
• Historical data: Cache indefinitely
• Use ETags for conditional requests

Optimize your API requests:
• Request only needed symbols
• Batch requests when possible
• Use webhooks for real-time updates
• Implement request queuing

Implement robust error handling:
• Retry failed requests with backoff
• Log errors for debugging
• Have fallback data sources
• Monitor API health

Keep your integration secure:
• Store API keys in environment variables
• Use HTTPS for all requests
• Validate webhook signatures
• Implement rate limiting on your end
• Rotate API keys regularly

Optimize for performance:
• Use connection pooling
• Enable gzip compression
• Process data asynchronously
• Monitor response times
• Use CDN for widget assets
