Status code 429 is an HTTP response status code that indicates that the user has sent too many requests in a given amount of time. This is often referred to as "rate limiting" and is used by web servers to prevent excessive traffic and ensure that all users have fair access to the server's resources. When a user receives a 429 status code, it typically means that they have exceeded a certain limit on the number of requests they can make within a specific time frame. This limit is often set by the server administrator and can vary depending on the server's capacity and the level of traffic it receives.
