The system will only charge for the HTTP 200 and 404 responses.
Each request has 30 seconds to return results successfully. It will retry several times until it reaches 30 seconds. If a request reaches 30 seconds, the scraper box will return error 500.
Each request has limit of 2mb max per request. In case you want to scrape a file, make sure you keep this in mind.
If you exceed your current limit, the system will automatically charge on a per-API-call basis.
