What HTTP status code indicates a Reddit API rate limit being exceeded, and what specific header provides information about the rate limit reset?

An HTTP 429 status code, meaning 'Too Many Requests,' signals that the Reddit API rate limit has been exceeded. When a client sends too many requests within a specific time frame, the API returns this code to prevent abuse and maintain service stability. The 'X-Ratelimit-Reset' header provides information about when the rate limit will reset. Its value is a Unix timestamp, indicating the number of seconds since January 1, 1970, 00:00:00 UTC, when the rate limit will be lifted, and the client can resume making requests. Handling a 429 error involves pausing API requests until the time indicated by 'X-Ratelimit-Reset' is reached. Other rate limit related headers are 'X-Ratelimit-Remaining', which indicates the number of requests remaining, and 'X-Ratelimit-Used', which indicates how many requests have been made. While these are helpful, 'X-Ratelimit-Reset' is essential for scheduling future requests.
