WebAutomation monitors your usage based on the number of requests you make to a website. The simplest way to describe a request is one page or URL e.g. if your extractor gets data from 10 product pages that would be considered as 10 requests
Not every request you make to a webpage for data will be successful. There are numerous reasons from wrong URLs to webpage temporarily unavailable, these unsuccessful request wouldn't be charged. We classify a successful request when we get a return 2xx HTTP status code. WebAutomation will only charge you for each successful.
