Usage Monitoring Best Practices

​
Automated Monitoring

import requests
import time

def monitor_usage(api_key, threshold=40.0):
    """Monitor data usage and alert when threshold is reached"""
    response = requests.get(f"https://data.quantcite.com/api/v1/data-usage/{api_key}")
    
    if response.status_code == 200:
        data = response.json()
        used_gb = data['data_usage']['used_gb']
        limit_gb = data['data_usage']['limit_gb']
        
        if used_gb >= threshold:
            print(f"WARNING: High usage detected: {used_gb}GB / {limit_gb}GB")
            return True
    
    return False

# Check usage every hour
while True:
    monitor_usage("your_api_key")
    time.sleep(3600)  # 1 hour

​
Usage Dashboard

async function createUsageDashboard(apiKey) {
    const response = await fetch(`https://data.quantcite.com/api/v1/data-usage/${apiKey}`);
    const data = await response.json();
    
    const usage = data.data_usage;
    const billing = data.billing_period;
    
    console.log(`
    ╔══════════════════════════════════════╗

Integration Tips

Regular Monitoring

Check usage regularly to avoid hitting the 50GB monthly limit. Set up automated alerts at 80% usage.

Usage Optimization

Monitor usage patterns to optimize your WebSocket subscriptions and reduce data consumption.

Billing Awareness

Track billing periods and plan your data usage accordingly. Usage resets monthly.

Error Handling

Implement proper error handling for invalid API keys and suspended accounts.
This endpoint does not require admin authentication and can be called by providing your API key as a path parameter. It does not count against your rate limits or data usage.
