HTTP Status Code 429 signifies Too Many Requests indicating that the user has sent too many requests in a given amount of time. This status code is a part of the Client Error category and is typically used to inform the client that they have exceeded the rate limits set by the server. Rate limiting is commonly implemented to prevent abuse, such as spamming or overwhelming the server with requests, which can lead to performance degradation for all users. When a client receives HTTP Status Code 429, it usually means they need to wait before making additional requests. The server may also include a Retry-After header, indicating how long the client should wait before attempting to make another request. This status code helps maintain fair usage of resources and ensures that the server remains responsive to legitimate traffic, ultimately improving the overall experience for all users interacting with the service.
