Throttling Mechanisms

Throttling mechanisms are server-side controls used to limit the rate at which an API or service processes requests from a specific user or IP address. The primary purpose is to protect the service from abuse, denial-of-service attacks, and excessive load that could impact overall performance.

Throttling can be implemented based on various criteria, such as requests per second, total data transferred, or concurrent connections. When a user hits the throttle, the system will reject further requests, typically returning a 429 Too Many Requests status code.

This forces the client to back off and wait for a cooldown period. Effective throttling is necessary for maintaining a fair and stable environment for all users on a shared platform.

For traders, it is a constant operational hurdle that requires smart retry logic and request management. If not handled correctly, throttling can lead to significant disruptions in automated trading operations.

It is a fundamental aspect of API security and resource management.
