ScraperAPI is proxy solution for web scraping.It is designed to make scraping the web at scale as simple as possible by removing the hassle of finding high quality proxies, rotating proxy pools, detecting bans, solving CAPTCHAs, managing geotargeting and rendering javascript.

We know that scraping is complex, and so is pricing. To properly reflect the effort it takes to scrape each site and make it easier for you to grow and scale, our pricing model is based on API credits. This also allows us to bring everything we have to bear on keeping Success Rates as high as possible and opens up all our features to you, rather than restricting them based on your plan.

Depending on the type of website you want to scrape and what parameters you need to use for a request, a different number of API Credits will be used for a single request.

Every plan with ScraperAPI has a limited number of concurrent threads which limit the number of requests you can make in parallel to the API (the API doesn’t accept batch requests). The more concurrent threads your plan has the faster you can scrape a website. If you would like to increase the number of concurrent requests you can make with the API then contact our customer support team.

In case your scraper is not utilizing the full concurrency thread limit of your Subscription, please make sure that its settings are correct and are set to utilize the exact amount of Threads that your Subscription allows.

In case you are still not utilizing all of your Concurrent threads, there might be something else blocking your requests on your machine. Please make sure you check both your Antivirus/Firewall and your Network for any issues. Another culprit might be the resource usage for the user on your machine.

You can adjust "ulimit" on both Linux and Windows machines to make sure that there are no restrictions on resource usage for the users set up on your machines. For Linux users, you will need to modify the file "/etc/security/limits.conf", and for Windows Users, you will need to modify your Registry Values. There are multiple guides that can be found on the Internet on how exactly this can be done.

When you send a request to the API we will route it through our proxy pools, check the response for CAPTCHAs, bans, etc. and then either return the valid HTML response to you or keep retrying the request with different proxies for up to 60 seconds before returning you a 500 status error.

Frequently, the API has higher latencies than sending requests directly to a normal proxy as average latencies typically range from 4-12 seconds (depending on website) and single requests can sometimes take up to 60 seconds. However, this is compensated by the fact that our average success rate is around 98%.

If you would like to increase the volume of successful requests you can make in a given time period then we can increase your number of concurrent threads. Contact our sales team to enquiry about increasing your concurrency limit.

If you like to reduce the latency of each request or reduce the longtail of some requests taking 20-30 seconds then you can use our premium proxy pools by adding premium=true to your request, or by contacting our support team to see if they can increase the speed of your requests.

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.

At the moment, we don’t have the possibility to roll over unused requests or credits. When your subscription renews, the requests are being reset. If you want to increase or decrease the amount of requests, please get in touch with our support team.

ScraperAPI offers a free plan of 1,000 free API credits per month (with a maximum of 5 concurrent connections) for small scraping projects. For the first 7-days after you sign up you will have access to 5,000 free requests so test the API at a larger scale. If you need additional API credits for testing purposes, please contact support.

Running out of API Credits before your plan’s renewal date does not have to be scary, nor does it have to stop you from scraping. Depending on your needs, you have 2 options:

• Set your Subscription to automatically renew when you run out of API Credits. From your Dashboard; you can set it to renew at 95% usage or at 100% usage; or

• Manually renew your Subscription when you run out of Credits, from your Dashboard

Yes, you can cancel your subscription at any time in your dashboard or by contacting support, you will not be charged for cancelling.

We offer a 7-day no questions asked refund policy, if you are unhappy with the service for any reason, contact support, and we’ll refund you right away.

You can change your card details anytime on the Billing page in your dashboard or by contacting support, who will help you securely change your card details.

Currently, we don’t offer a pay-as-you-go option with the API. All our plans are monthly subscriptions that reset each month.

Currently, we don’t offer bandwidth based pricing. All our plans are based on the number of requests you make to the API each month.

Currently, we don’t have an option to purchase individual proxies from our pools.

To enable JavaScript rendering you simply need to add the render=true parameter to your request. The API will then route your request through a Chromium instance and render any JavaScript on the page, before returning the HTML response back to you.

All JS Rendered requests cost 10 API Credits. However, if you use JS Rendering with premium proxies, it will cost 25 API Credits, and if you use ultra premium proxies with JS Rendering, the cost will be 75 API Credits. We highly recommend that you only use JS rendering if you absolutely need it to extract your target data, as JS rendering will increase your latency and can reduce your success rates which can reduce the volume of requests you can process through the API.

To avoid rendering unnecessary images, tracking scripts, etc. that will slow your requests down, the API doesn’t render everything on the page by default. Sometimes this might include some data that you actually need. If you find yourself in such situation, you can instruct the API to wait for a specific selector to appear on the page through the use of the wait_for_selector=x parameter, before we return the final rendered response back to you.

If you find yourself in need of help, you can contact our support team here

The rendering concurency (burst limit) is set to 10req/sec by default. This burst limit controls the number of rendered requests you can start each second. For example, if each rendered request takes 25 seconds to complete, and you are consistently sending 10 requests per second, you could have up to 250 rendered requests running concurrently at any given time (10 requests/sec * 25 seconds). If you need to handle more rendered requests concurrently (Enteprise users only) please contact our support team for assistance.

Business and Enterprise Plan users can geotarget their requests to the following 13 countries (Hobby and Startup Plan can only use US and EU geotargeting) by using the country_code flag in their request.

Other countries are available to Enterprise customers upon request.

At the moment the API doesn’t support state or city level geotargeting with our proxy pools. However, on request we can implement this for Enterprise level users.

We use residential proxies as fallback proxies within our standard proxy pools if a request has repeatedly failed. However, if you would like to exclusively use our residential proxy pools then you can enable this functionality by adding premium=true to the requests you send to the API.

Our premium proxy pools contain mobile IPs, however, if you want to exclusively use mobile proxies then contact our support team who will be able to create a custom plan for you.

Along with constantly fine tuning our proxy and header pools, within the API we’ve built in numerous anti-bot bypasses that enable the API to bypass most challenges thrown by anti-bots. Generally, your success rates will be a small bit lower on sites that make heavy use of anti-bots, however, you should be able to scrape the site reliably at scale with the API.

In the case that the API is completely blocked by a site or you are experiencing a very low success rate (under 70%) then please let our support team know about the issue.

This is generally due to the site using either a combination of 2 or more anti-bots in tandem or using a customised version of the anti-bot with higher security settings that stop the general bypass from working. In cases like these, one of our engineers will put in place a custom bypass for you if you contact our support team.

After we receive a HTML response back from your target website we automatically run the response through our ban and CAPTCHA detection algorithms. If the API detects a CAPTCHA the API will retry the request with another IP and have the blocked IP unblocked in parallel. This ensures that you don’t have to wait until the CAPTCHA is solved before you can retry the request.

We have a CAPTCHA database with thousands of bans and CAPTCHA types that we use to detect whether a request contains a CAPTCHA or has been blocked by an anti-bot. If you are getting a CAPTCHA or an anti-bot message back as a successful status 200 request then just let our support team know and they will add this new CAPTCHA or anti-bot message into our database so it will be detected in the future. Triggering the API to keep retrying the request until it gets the correct successful response.

Currently, the API doesn’t solve CAPTCHAs that are permanently embedded on the page, like those often found on forms or buttons to reveal personal information. You will need to use a dedicated CAPTCHA solver service to unlock these CAPTCHAs. On Enterprise Plans, we can implement this functionality for you upon request.

Inspect your target URL to see whether they are using botblockers such as Cloudflare, Datadome or Cloudfront. These blockers make the domain more difficult to scrape, and you may need to use our premium or ultra premium proxies.
