All these years later this issue is still present. I am just learning scraping in Python. I am getting a 503 error. Seems to be an issue with parsing UK Amazon web pages. Any advice on this? This is using bs4. I just get an error message along the lines of it being a problem their end and they are looking into it. I looked into using the official API mentioned above. It seems you can't use the Product Advertising API unless you have been accepted as an Amazon associate, as the API requires an Associate ID as part of its authentication.
