Traditional Scraping vs. Proxy APIs – Selecting the Best Method for Your Project
Knowing what the competition is doing, from pricing to marketing strategies, can help any company to compete even with the big guys. One of the ways to do this is to use web scraping, a process that allows you to collect data across websites of all types to use to fit your needs. Web scraping helps companies make informed decisions about the products they are selling, what they are charging, and how to target customers. When it comes to comparisons like web scraping vs API, it helps to know which strategy best fits your specific needs. Here is what you need to know.
Table of Contents
The concern many businesses have is just how complex websites today are. They have improved their security by leaps and bounds, and that makes it harder for a web scraper to navigate across these sites and extract necessary information. As a business, you may not be sure if you should invest in a web scraping specialist or purchase a service that can handle the tough jobs, like data parsing and CAPTCHAs for you.
API vs Web Scraping: Why There Are Challenges in the First Place
Traditional web scraping tools like Beautiful Soup and Python’s well-known Requests tools have long been reliable options for getting the content you need. These tools work in a very straightforward manner. You choose the target URL you want them to scrape, and they send a request to download the HTML code from that URL. Then, they extract the data that you want to pull from it. You can also adjust the scraper to pick up specific needs or navigate various situations.
The problem comes when you consider the steps websites have taken to completely lock down their websites, preventing bots like yours from navigating them. Anti-bot systems are in place – and have grown in use by many organizations. The problem is not likely your effort to capture information but rather the malicious bots that cause havoc for website developers. To avoid these risks, various methods are put in place to make it harder for web scraping to happen.
This means that it is not very difficult for data to be obtained from traditional scripts. That is frustrating, given the wealth of value in that data. Now, to gather more information, you need more resources and better knowledge.
What Is API Proxy?
The web scraping vs API conversation starts with an understanding of an API proxy is. Also known as a web unblocker or simply a web scraping API, this type of tool integrates into a proxy server. What this tool does is combine several proxy types and methods for unblocking websites in the backend. In short, it opens the door to capture more of the information and data you need and want to capture even on these hard-to-access websites.
The benefit of a proxy API service is uninterrupted access to the target you select. What’s more, it works no matter the type of protection mechanism that the website is using. In situations where a request for a URL fails, such as when there is a CAPTCHA block, the proxy API will adjust the configuration as necessary and then retry. It keeps doing that until it gains access.
APRI proxies also come with additional features that are not commonly found on a traditional proxy service. For example, you can establish sessions, and when you do, you can then select a specific location setting. This will then allow you to reach co-ordinate and ISP level.
The proxy service API process is a bit different than what you would use for other methods, but it is still very effective. It will use a web unblocker that includes a hostname and a port with authentication details. You can add various parameters important to your task, such as location credentials. You can also send them a custom header. The API adjusts to the configuration and handles the web scraping like a pro.
The Advantages of a Proxy Server for Web Scraping
When you consider API vs web scraping, you may not be sure you want to make a switch. However, when you take a look at some of the advantages of API web scraping, you are likely to see numerous benefits to this process.
Success rates are very high. One of the best reasons to use API web scraping is simply because it works. Proxy APIs can have a high success rate, even into the 90% range, which is far more than what many will get from large companies that have anti-bot systems in place to limit your access.
Request and CAPTCHAs are managed. Here is another valuable benefit to API vs. traditional scraping. The proxy API will handle the CAPTCHAs. It does this by avoiding the challenge in the first place. It does not force its way through it. For example, if a website has a CAPTCHA requirement on it, such as a pop-up that shows, it can be avoided. In some situations, they may still become a slowdown, but the proxy API will continue to try until it gets through.
Finger spoofing tools. Another benefit to using API vs scraping is that it provides browser fingerprint spoofing. That means that it handles the browser fingerprints by automatically selecting the right request headers, as well as passive fingerprints, and other points you need. This means that you do not have to write unblocking logic on your own, which is certainly a time saver.
Easy to integrate. Web scraping vs API use for web scraping can often come down to this point. API scraping is easy t integrate. You have a single endpoint in hostname:port. This allows you to add a code in place of the traditional proxy server.
Web Scraping vs API: The Downside
While API vs web scraping seems to show that API web scraping is the best route, there are a few key factors to consider that may limit your overall desire to use them.
One of the challenges is that the proxy API can handle JavaScript. However, they are not flexible when it comes to dynamic content. Most of the time, these tools do not expose the parameters that are necessary to interact with a page that is set up as dynamic content. This means that the proxy API route is not ideal if you are looking for access to websites designed for dynamic content or those that require user interaction.
Also notable is that there are not many proxy APIs that provide support for integration with a headless browser library. That means that if you are using tools like Playwright or Puppeteer, you may find that the proxy API is not going to work well with these tools.
You also have to consider the price. Depending on the solution you select, you may find that a proxy API service will cost a bit more than other types of tools, and for some projects that added cost may not be worthwhile.
When to Use Web Scraping vs API
As you think about the various factors that are important to your project, consider the risks associated with web scraping. The following are some of the most common anti-bot blocking tools in place that could limit your reach if you do not use a proxy API:
- Rate limiting: This process aims to control the traffic flow to the website. For example, the website owner may choose an IP address to monitor visitors coming from it. If you are not using a proxy service or VPN, it could stop you.
- CAPTCHAs: One of the most common reasons to make the switch is that they are becoming more common on websites and tend to be challenging for most bots to navigate.
- Browser fingerprinting: This method is used to track hardware and software parameters that must be managed while web scraping. You need to emulate headers such as user agent to hide your identity.
For those considering web scraping vs API use, know that both methods have benefits. While you will need to have some experience and knowledge to use them, API proxies are an option to help many organizations navigate the growing number of anti-bot tools in place. With a wide range of tools out there, using proxy APIs to help you navigate the challenges is easier than you realize.
