ScraperAPI routes your requests through proxy pools with over 40 million proxies and retries requests for up to 60 seconds to get a successful response, however, some of your requests will fail. You can expect 1-3% of your requests to fail, however, you won’t be charged for these failed requests. If you configure your code to automatically retry failed requests then in the majority of cases the retry will be successful.
If you are experiencing failure rates in excess of 10% then contact our support team who will look at tuning the API to yield a higher success rate.
