If the body of your request is larger than 100 KB, Web Scraper API returns a ‘413 payload_too_large’ error. The limit applies to the JSON you send, not to the size of the page you scrape. Usually, a request body is far smaller than the limit.
If you get a ‘413 payload_too_large’ error, send only the documented fields and try again. Requests that end in an error don’t use credits.
