# Rate Limit Policies

**Overall Limit and Application** For all public endpoints of the application, the rate limit is set to 500 requests per minute. This limit is applied per IP address or valid authentication token, ensuring that each entity (IP or token) has a fair usage quota.<br>

**Rate Limit Operation**

* **Request Limit:** Each valid IP or authentication token is allowed up to 500 requests per minute to the public endpoints of the application.
* **Time Windows:** The request count is tracked in 1-minute time windows, resetting every new minute.
* **Rate Limit Feedback:** When the 500 requests per minute limit is reached by a specific IP or token, subsequent requests within the same 1-minute period will receive a response with HTTP status code 429 (Too Many Requests).

### BEST PRACTICES FOR DEVELOPERS&#x20;

To avoid hitting the request limit, we recommend following these best practices:
