Implementation Best Practices

1. Authentication: Always secure your API keys and never expose them in client-side code
2. Rate Limiting: Implement proper request throttling to avoid hitting API limits
3. Error Handling: Build robust error handling for network issues and API errors
4. Data Caching: Consider caching frequently accessed data to reduce API calls
5. WebSocket Alternative: For real-time data, evaluate WebSocket connections

Frequently Asked Questions

Q: How often should I poll the API for price updates?
A: For most applications, polling every 15-30 seconds provides adequate freshness without hitting rate limits.

Q: What's the maximum number of trading pairs I can request at once?
A: The system allows up to 100 trading pairs per request for most endpoints.

Q: How do I handle API key rotation?
A: Implement a key management system that can seamlessly switch between active keys during updates.

Q: Are there regional restrictions for API access?
A: Currently the API is globally accessible, but check our terms of service for updates.

Q: What happens if I exceed my rate limit?
A: You'll receive a 429 status code and should implement exponential backoff in your retry logic.

Q: Can I access historical data beyond recent trades?
A: Historical data endpoints are available in our premium API tiers.

Final Recommendations

For developers building trading platforms or market analysis tools, proper API integration is crucial. Always test your implementation thoroughly in a staging environment before going live.
