The API must audit rate-limiting events.

The API must audit rate-limiting events to ensure security, system stability, and fair resource usage. Rate limiting is essential for protecting the API from abuse, such as denial-of-service (DoS) attacks, where an attacker could overwhelm the system with excessive requests. By auditing rate-limiting events, the API can track when users or services exceed predefined thresholds, providing insight into potentially malicious behavior or misuse. These logs help detect patterns of abuse, such as attempts to bypass rate limits or automate excessive requests, allowing for timely intervention.
