The error "Request failed with status code 429" occurs because the website you are trying to get data from has implemented rate limiting. 

This means that the website is limiting the number of requests that can be made to the site within a certain time period to prevent overloading the server or scraping of data. When this limit is exceeded, the server returns a "429 Too Many Requests" response code to indicate that the client has exceeded its allowed rate limit. 

To resolve this issue, you could try reducing the frequency of your requests or implement a wait time between requests to comply with the rate limit imposed by the website.
