Rate limits are essential for maintaining system stability and ensuring fair usage of API resources. Below is a guide to understanding and managing them effectively:

🔑 What Are Rate Limits?

Rate limits restrict the number of requests a user can make to an API within a specific time frame. This prevents abuse and ensures reliable service for all users.

  • Purpose: Protect against denial-of-service attacks and resource exhaustion.
  • Common Metrics:
    • Requests per minute (RPM)
    • API calls per hour (APC/H)
    • Burst capacity (short-term spikes)
  • Enforcement: Typically handled via middleware or API gateways.

🛡️ How to Set Rate Limits

  1. Define Thresholds: Based on your API's capacity and user base.
  2. Choose Time Windows: Use sliding windows for better accuracy.
  3. Monitor Usage: Implement analytics to track API activity.

⚠️ Key Considerations

  • User Experience: Avoid overly restrictive limits that hinder legitimate use.
  • Documentation: Clearly communicate limits to developers to prevent errors.
  • Adjustments: Allow for dynamic adjustments during high-traffic periods.
