Tips to Buying Private Proxies

LouiseeLambertf — Mon, 24 May 2021 09:08:07 +0000

As the need to work in a remote location and increased desire to maintain anonymity among internet user create the demand for the private proxies. The use of a virtual private network has been the most popular type of proxy used in the world. The first type of serves to be used were named Wingate (Smith & Robles, 2013). Wingate, window services enabled the sharing of internet destination dial-up among different users. With the increasing development in technology more advanced type of proxy continues to emerge and incidence of their misuse continue to increase.

Functions of a Proxy Server

A proxy can be defined as the intermediary on the connection between computers two or more over the internet. The primary function of the proxy is thus in establishing a permanent and a network link between two devices (Smith & Robles, 2013). For instance, opening a virtual private network from home may enable one to access computers systems in the workplace. The permanent connection created is therefore established as the default channel through which future communication will take place between the two computer systems. The connection between the computer and the remote VPN server does not only guarantees animosity in connection but in additions, it provides security through encryption of the communication between the two points.

The security provided make it difficult for a third party to identify the address and the sites that a proxy user accessed despite noticing the traffic flow. One similar that the use of any proxy attempt to provide is to conceal the originating address of the accessing system and only reveal the address of the server. However, apart from enhancing security and animosity proxy are used to serve other diversified purposes. For instance, one may use to access restricted content over the internet which would be deemed inaccessible. The fact that access to some cite is restricted to specific geographic locations require user in restricted geographical location to first establish connections with proxy servers in the home country to guarantee access to the controlled content.

For instance, individuals in France may use a proxy to access media contents that are only meant to be used in the United States. in such an attempt to bypass the restriction the user need to first to create a permanent network with a proxy server in the United States to be successful. On the other hand, the user proxy technology is not limited from illegal misuse particularly considering the increasing incidence of cyber-related crime. Hence, cybercriminals heavily rely on proxies as a measure to conceal their address and make it hard for the law enforcement agencies to track them.

Additionally, in large business organizations use of proxy server may serve the purpose of administrative control or providing security. In complementing the security of the enterprise, the proxy server may be used to monitor traffics as well as access to user’s privacy details. However not all of the user relies on the proxy with the primary aim of hiding their identity, some users rely on it based on its ability to provide protection against malware that may restrict internet access when the internet connection is working slowly.

On other hand proxy servers, the act as intermediaries provide security and shield the host internet destination. Users of proxies can subscribe to various service providers. Though the network administrators may provide critical security against unwarranted intrusion, the increasing threats continue to make the connection much more vulnerable, and thus administrators' attempts may not be sufficient in providing adequate security, and hence there is the need to consider using a proxy server.

Types of Proxies

Majority of the people do not realize that proxies are different from each other and their different feature distinguish certain capability from each other. Therefore, the ignorance led to some people making the wrong choice while selecting the proxy tools to purchase. Knowing the different type of proxies and their feature not only ensure that they achieve their objectives but also save on cost during purchase and future maintenance. When considering to purchase a particular type of proxy the user need to take some precautions on the type of proxy to purchase and make sure that the specific proxy aligns with the required performance. The user must have some necessary knowledge on the distinct feature and different functions of proxy servers.

First, it’s worth noting that proxy servers are classified into two broad categories, the transparent and anonymous type (Smith & Robles, 2013). On the transparent proxy, this type of services does not conceal the request of the connecting system. Such proxy serves to make it possible to identify the IP address of the requesting system. Transparent proxies are most widely used to connect computers in an internal environment where concealing the identity of a requesting system is not necessary as the network is generally secure from the external threats. Thus, the transparent proxies do not conceal any information contained in the traffic. Also, apart from their wide use in internal networks they are used to access sites that may be inaccessible in a particular geographical location.

On the other hand, anonymous proxy servers transfer the users request without revealing their identity. Thus the proxy serves request without exposing the IP address of the users at the other end. It effectively conceals the address of the requesting system by utilizing a different IP address (Azumaya, Shiori & Manabu, 2014). Moreover, the proxy serves to ensure that the user system maintains high-level performance by providing additional storage on the previous request made. Moreover, it is worth noting that not all anonymous proxy serves to provide high-level information security. For instance, despite some less advanced proxies maintaining anonymity, they do not conceal their identity as proxy servers and thus making network administrators aware of its use. Purchasing such a proxy is not advisable for us as it may provide access to private information.

On the other hand, more advanced proxy servers do not reveal their identity as a proxy in the websites they visit this make them more convenient for concealing identity as well as protecting users' privacy.

Apart from anonymous and transparent proxies, other categories of proxies include the reverse and intercepting proxy. In reverse proxy, it acts as an intermediary that sends the user request to a specific private network through a firewall. On the other hand, an intercepting proxy enables the combination of different request and redirect them to the internet destination without any additional configurations.

Factors to Consider When Choosing the Proxy Services

Security

Therefore, having adequate knowledge on the type and feature that each type of proxy possess is critical in determining whether an individual purchase a product that will achieve the intended objective while on the other hand providing value for money. On choosing the type of proxy to purchase considering the level of security provided, its ability to maximize use system performance by providing additional memory and its capability to monitor traffic are some of the features that require to be considered before deciding to buy.

Number of Users

Moreover, need to avoid public available proxy’s s useful in ensuring that one maintains a high internet connection as the majority of then experience overload from numerous users thus affecting the level of performance over the internet. Further to overt facing the challenge of a poor connection in the future there is need to examine the bandwidth that the proxy providers have allowed since it limitation will automatically affect the performance of the user system (Azumaya, Shiori & Manabu, 2014).

Furthermore, another issue that affects the performance of the proxy is on the number of users that access the internet using that particular server. A proxy server that is shared by numerous user may perform slowly compared by the one that serves a few individuals (Triantafillou & Aekaterinidis, 2010). Thus, considering the number of individuals that a proxy serves to connect with offer better insight on the expected browsing speed and hence relying on a server that is shared by less individual is a better alternative where speed is a concern.

On improving the security of the user, there is a need to evaluate the available options of guaranteeing the users privacy. One need to choose whether to subscribe to a shared proxy which is considerably cheaper and less private or getting a dedicated one that provides a guarantee to user’s security. A shared proxy increase risk of privacy breach from a third party while a dedicated proxy is tailored purposely to serve the interest of the client and hence the security of the information is highly given much priority.

Free or Paid

Therefore for the user who wishes to maintain his identity concealed and additional information security considering installing a dedicated proxy server is the better alternative.

First, on the list of the proxies to avoid is those that are provided for free or attract a cheap subscription rate. The fact that running and managing a proxy server demand high capital contradicts the reason why an enterprise will be willing to provide its retail services at no fee or at a rate that generate less revenue incapable of efficiently managing the server. In relation, the users need to compares then price offered with the level of server performance.

Considering the high cost of purchasing hardware and need to settle personnel services the proxy server may be providing service to a large number of users and hence leading to a low-performance level (Kenneth & Stephanie, 2014). Moreover, a company that provide proxy service freely may allegedly intend to use the customer data for commercial gain without their consent. Hence, when purchasing a proxy server should place much emphasis on acquiring a paid service since it guarantees a source of accountability and hence rare to intrude on its privacy.

For Trust

Another critical element for consideration is trust, particularly on the reputation of the proxy service provider. By using a proxy server all the request logs and visits stays on the proxy server and can be viewed by server administrators. Therefore, the fact that individual browsing logs are private information, it is prudent to purchase proxy from a trusted company that may not share the data with third parties without my consent. The cache system makes a lot of useful information available for the proxy service provider to access including the sensitive password.

Further, there is a need to examine whether the proxy communication has full encryption. The fact that the majority of the people do not understand the difference between encrypted and non-encrypted make them vulnerable to third-party interception. Therefore when buying a proxy server priority to be placed on obtaining fully encrypted software and thus guarantee security from a potential interception that may siphon sensitive personal details such as credit card and bank details.

Additionally, apart from making the proxy purchase from a trusted company, it is necessary to ensure that the vendor provides after-sales free support services. Choosing brands that provide technical support for their software create confidence in the quality of the products. Moreover, free after-sales service is economical than considering to hire an expert to service and more avoid unnecessary interference during poor performance or when the proxy is faulty.

Compatibility

About choosing the proxy service provider, purchasing proxy tools from reputable and trust companies provide additional advantages as much often they tend to have modified their tools to be compatible with various tools and hence are more generally convenient in their usage. Therefore, when buying the proxy tools not only does the user need to consider after sales support but a more critical aspect that determines future usability is the compatibility of the proxy with other network tools. Hence, before making a purchase decision, one has to compare the compatibility of the necessary tools while considering the purpose of the proxy. For instance, if the user aims at enhancing online marketing through social networking, he/she may consider the compatibility of the proxy with tools such as scrapebox.

Free Trial

There is a need to take a keen on the review from past user based on their experience in using the particular tool. However, considering that reviews may be full of prejudice and sometimes used as a marketing approach a more effective manner to supplement the exposure on the performance of the tool is by relying on requesting for a free trial before purchasing the proxy tool. The free trial offers the best experience on how the proxy under consideration is expected to perform.

After the free trial experience, one has to assess how the experience met the various need and expectations and hence provide a better platform to acquire perfect knowledge about the product before committing to buy. Additionally, getting a first-hand experience through free trial will provide a better insight into the speed of the proxy tools. Some proxy tools limit their speed and thus depending on the purpose it is critical to evaluate its online performance before making a conclusive sale decision.

Ceanliness of the IPs

Additionally, it is critical to consider the number of proxies that are available in one tool. Having a high variety increases performance and minimize chances of being denied access when some IP addresses are banned from requesting from particular sits. Moreover, buying in bulk is more economical and hence considering purchasing multiple proxies save on considerable cost.

Location of Coverage

Considering the geographical location is critical in ensuring that the proxy tool will achieve the intended action. The fact that geographic location influence the effectiveness of the proxy tools considering that some regions are regarded as higher risk than others makes it essential for a company or individual to first consider their country of choice before making the purchase.

If the user proceeds to buy a proxy tool without considering the country that the proxy identifies itself with, it may result to access challenges in the future as some cites may ban connections from countries regarded as high-risk areas. Therefore, when buying the proxy from any vendor being so much economic may lead to purchasing of low-quality proxy which may be described as less secure, slow performance and one that jeopardizes the privacy of the user sensitive information especially due to lack of encryption.

Conclusion

In conclusion, by going through the article, one gets a clear insight into the need to understand how different proxies their distinct features and weakness before making a purchase decision. Before getting enough knowledge on the different categories of proxies, one may be tempted to consider public proxies as the appealing alternatives owing to their low price and popularity.

However, after a deep analysis, it gets clear despite the high cost of purchasing a dedicated server is the best alternative considering its high level of privacy and guarantee for technical support from the proxy tool vendors. After going through this article, you become more enlightened on the step to follow to acquire a proxy that offers value for money. However, after installing the proxy tool, there is a need to maintain the serve security updated to prevent future network intrusion in addition to maintaining contact with the vendor to provide support when technical supported is needed. Additional precaution measure to ensure security include to avoid sharing your proxy with other user and hence reduces its vulnerability from attacks.

Instagram Scraper 101: How to scrape Instagram posts, comments…

LouiseeLambertf — Thu, 20 May 2021 02:59:35 +0000

Does any data on Instagram appeal to you, and you want to extract them on a large scale from the platform? Then scraping is the only way out. Come in now to discover the best Instagram data Scraper in the market – and how to build yours.

Instagram, the popular photo, and video-sharing social media platform owned by Facebook is a huge source of social data. Unlike Facebook, Instagram does not hold as much personal data as Facebook does. However, the wealth of other information that still has a personal touch to it is overwhelming, especially among millennia. Data of interest on Instagram includes user profiles, posts (images and videos) – and their associated comments. Social researchers and businesses are in dare need of these data for their analysis in other to fine-tune their workflow, better understand their audience, create better content, and carry out other researches.

However, the official Instagram API only provides you access to your own Instagram data with good number restrictions in terms of API calls and data limits. If you must access publicly available data not tied to your own account, then you must work outside the confinement of the official Instagram API, and this means making use of automation tools known as Instagram scrapers. An Instagram scraper is a computer program that automates the process of extracting data from the Instagram platform. It does so by sending HTTP requests to web pages of interest in other to download them, parse the required data out of the page – and save it to a database if necessary.

This article will recommend the best Instagram scrapers in the market to you and also show you how to build one for yourself if you know how to code. Before that, let take a look at an overview of scraping Instagram.

Instagram Scraping – an Overview

Instagram is very clear on the use of the scraper, crawlers, and other automation bots on its platform. According to what is contained in the Instagram term of usage, the use of web scrapers on its platform is prohibited. Despite this, people are still actively scraping data from Instagram – and you can’t blame them; the official Instagram API isn’t helping matters. However, that people are not scraping Instagram does not mean you will be able to do that. Instagram has one of the most strict, effective, and intelligent anti-bot system in place to prevent automated access and traffic on their platform. They have been at the forefront of fighting bots in the industry, shutting down a good number of services such as the popular Mass Planner. Being that as it may, with the right system in place, you can scrape data from the Instagram platform at any scale without being detected and blocked.

The most important tool you have to take care of is proxies. Yes, Instagram tracks IPs and is very smart at detecting proxies, and as such, mobile proxies are the proxies of choice. However, if you can’t afford them, you can use residential proxies.

How to Scrape Instagram using Python and Selenium

Except you can reverse engineer the Instagram mobile application, your focus should be on the Instagram web application as that’s the one you can easily replicate its requests. The Instagram web application was built heavily with JavaScript to provide you a near-native and responsive experience, and as such, you have a lot of XHR and AJAX requests to deal with.

This makes the duo of Requests and Beautifulsoup not suitable for scraping Instagram. You need a way of rendering and executing JavaScript, which headless browsers can. As a python developer, Selenium is the most popular and powerful browser automation tool you can use to control browsers in headless mode. [su_youtube url="https://www.youtube.com/watch?v=4UqQt7dF9a8"] As you already know, there are some data available publicly on Instagram you can access even without logging in. These include profiles, posts, hashtags, comments, and places. I will advise you to focus on this and others that won’t require a login. You know why?

Accessing Instagram with an automation tool while logged in makes it easy for the anti-bot system to sniff you out, and when that happens, you risk not only getting your IP blacklisted but also your account banned. I know you can create accounts to use for your scraping work, but you also need to be good at engineering your bot to evade the check activated on logged-in accounts and their activities.

Below is a small Instagram scraper for scraping comments under posts. It is a simple proof of concept scraper and built using Python and Selenium to show you how easy it is building and Instagram scraper.

from selenium import webdriver

class InstagramScraper:

    def __init__(self, post_url):
        self.post_url = post_url
        self.comments = []
        chrome_options = webdriver.ChromeOptions()
        chrome_options.add_argument("--headless")
        self.chrome = webdriver.Chrome(chrome_options=chrome_options)
    def scrape_comments(self):
        browser = self.chrome.get(self.post_url)
        content = self.chrome.page_source
        comments = 
self.chrome.find_element_by_class_name("XQXOT").find_elements_by_class_name("Mr508")
        for comment in comments:
            d = 
comment.find_element_by_class_name("ZyFrc").find_element_by_tag_name("li").find_elemen
t_by_class_name("P9YgZ").find_element_by_tag_name("div")
            d = d.find_element_by_class_name("C4VMK")
            poster = d.find_element_by_tag_name("h3").text
            post = d.find_element_by_tag_name("span").text
            self.comments.append({
                "poster": poster,
                "post": post
            })

        return self.comments
    
post_url = "https://www.instagram.com/p/CAbDmzDnSvn/"
x = InstagramScraper(post_url)
x.scrape_comments()

What You Need To Know About Proxies

LouiseeLambertf — Tue, 11 May 2021 08:49:57 +0000

People working in the corporate network environment will know and understand the meaning of ‘proxy server’ and that without it, it is impossible to access websites and other networks.

Most people have not about the term or may have come across it on the browsers of their devices but have never paid attention to its meaning.

This article is written specifically for them. This article will explain the benefits and the more reason why they should understand and use proxies.

A proxy server is an intermediary or linkage between the internet and the device. It makes communication between your PC or device and the worldwide web (www). If you visit a website like facebook.com from your browser which is set to a particular proxy server, a request is initiated and sent to the proxy server. The server then serves as an intermediary and sends the request to the server that is hosting the website. The host server then sends the page to you through the proxy server. Proxy servers are application-level gateways.

Anyone will love to protect their identity and to boost his or her security from getting damaged, tampered with or hacked by a third party. There are thousands of free proxy servers, but it is advisable to use the paid or premium versions to be certain of efficient work.

The forms of proxy servers are forward, reverse and open. The forward proxy is the standard proxy. It serves as the gateway between a PC or device and a wide and large network. The reverse proxy serves as the gateway between a corporate Local Area Network (LAN) and the web. Most times, the LAN networks are a small group of servers. The open proxies are free proxies that can be assessed by any user online. They are known as “public proxies.”

There are more types of proxies.

Transparent proxies

Transparent proxies are typical examples. They are found near the exit-point of a corporate network. They mainly help to centralize the network traffics. These proxy servers are associated with a gateway server that separates the local network from the Internet and a firewall that serves as protection of the local network from external intrusion.

They also allow data to be scanned for the purpose of security it is delivered to the client on the network. These proxies also serve as admin and monitor of the traffic in networks.

Anonymous proxies

Anonymous proxies are meant to hide the IP address or location of the user. They also allow users to access materials that are blocked by firewalls of the organization or server and to bypass the IP address ban. And one of their most important uses is to intensify privacy and protection from attacks by hackers. A proxy can also be highly anonymous.

These types will protect the identity of the clients and present a non-proxy public IP address. They do not only hide the IP address of their users, they also give access to the sites that block proxy servers. I2P and TOR are perfect examples of highly anonymous proxies.

More...

Socks 4 and 5 proxies are proxy service providers for the UDP data and DNS lookup operations. There are some proxy servers that offer both socks 4 and 5 proxies. A DNS proxy helps to forward domain name service requests from Local Area Networks to Internet DNS servers. While they do that, they are also caching for great speed.

Benefits of Proxies

Proxies work in a way that they cache the contents when given access, before delivering it to the user that made the request for the data. After the first access, subsequent data will load faster because of the different connections between the hosting server and the client of which that of the proxy server is the better. The benefits of proxies are well-explained below.

Control of Internet Usage

Organizations, companies, airports, restaurants, and other establishments make do with proxies a lot. They do this to restrict their employees and other users from accessing malicious websites and contents during work hours. They also ban access to some file extensions that are from unreliable sources which can have and drastic effect on the computers.

It is very easy to spot ‘misbehaving users’ with detailed reports and logs of contents and sites that they want to access. Websites containing malware or phishing links can be prevented by an admin from allowing access to them.

The Anonymity of IP Address and Location

This is a very good benefit of proxy servers. They prevent the website you access from being able to log your real IP address. Your identity will be protected and it will only be able to log the proxy server’s IP address instead. So, that means when you browse online, you are not visible and your anonymity is preserved.

Your IP address can reveal a lot about yourself, your country and the city you are from. Cybercriminals can use the details of your IP address to find out things about your ISP, zip code, and even to the extent of knowing your street and where you work. A hacker can get access to your IP address through a data breach or leak on a website you visit.

It is very important to disable the webRTC leak of the browser you visit. This will help to disable any form of leaks that will reveal your details through your IP address. This is a very useful benefit. Also, for those that own a company with an international presence, they will surely have different visitors and subscribers from different countries. There will be a need for a great proxy server that will detect the location of your website visitors and load pages and contents that are relevant and appropriate for the local market of their country.

Access to Blocked and Restricted Content

There are countries that make do of ‘geo-restrictions to prevent access to contents by the citizens of their countries. These laws of restrictions are made by the government legislature or rule. Most times, the reason for this online restriction is because of network and copyright regulations. At this juncture, a proxy server hides your IP address and restrictions to access websites that are banned will be breached.

NOW TV is a website that cannot be accessed by people outside the UK. Using a proxy server will give you elusive access to it. You can also use a proxy server to bypass and breach network restrictions at workplaces, and establishments. Restrictions that prevent users from accessing certain contents or websites will be breached easily.

Enhanced Speed and Bandwidth Saving

Using proxies will help save important bandwidths. This happens when proxy servers compress traffic, cache files, and web pages from the Internet. Also, ads are blocked from websites before they are accessed by the computer. Companies like the New York Times, CNN news, et al. with thousands of employees will be able to save bandwidth and improves internet performances.

There is Improvement of Security and Privacy

Proxy servers enhance security measures and boost privacy benefits. Malicious and prying eyes can be well prevented from spying into your logs, history, and transactions when you encrypt your request by configuring a proxy server. The server prevents malware sites from any form of access.

An organization can make do with a VPN, coupled with their proxy servers to allow access by users. A VPN provides a direct linkage to the company’s network for external users. With the use of a VPN, the company can control the limit of access to the resources by their users. A secure connection is also provided for the user and the company data is protected.

Individuals, establishments, and organizations make use of proxy servers to surf the internet privately. Personal information is kept private because the destination server is unable to detect the source of the request made. Proxy servers are used in business networks to improve security by preventing malicious websites from distributing malware. They are set to block that malware and to provide encryption services so that your data are shielded from third parties.

There is Reduction in the Load Time

Since proxy servers can cache data, web pages are stored for later when they are accessed. The next time a web page is requested, the browser will display it faster to the user because it was previously cached. This will only happen if the particular proxy server’s local cache already has the web page. If not, it may take time to load on the browser.

In conclusion, this is all about the benefits of using proxies. As you can see, proxy servers are very good for your business, privacy, security, and efficiency of your network connection. A proxy server can also be configured in different ways, based on the admin and the purpose of their use.

For maximum and efficient use, it is advisable to understand why you are using it, who controls it, and whether it is from a trusted party. There are public proxies that are not to be trusted and it is good to beware of them. They may tamper with some important information that is very vital.

Scraping Proxy API – Automatic Proxy Rotation for Concurrent requests

LouiseeLambertf — Mon, 10 May 2021 08:50:52 +0000

Are you looking for the best proxy API for web scraping and crawling? Come in now and discover the best ones in the market. You will also be learning about why you should use them and their downsides.

Are you new to web scraping and proxy management? Chances are there that your web scraper keeps getting blocked and requesting for Captcha to be solved. If this happens often, then you might want to drop using general proxies altogether and switch to using proxy APIs, which are optimized for web scraping. Even though most proxy providers will claim that their proxies are optimized for web scraping, only a few are. Most of them are general-purpose proxies with little consideration for the unique requirements of web scraping.

Proxy APIs for web scraping put into consideration the requirements for a successful scraping. While some providers are strictly providers of these APIs, others are web scraping services that allow people to use their private proxy pool. Generally, providers of proxy APIs for scraping do not disclose much about their proxy pool – you wouldn’t know whether their proxies are self-built or they rent from proxy providers. However, their pricing is much flexible compared to that of regular proxy services, as it is based on the number of successful requests sent.

What is a Proxy API for Scraping?

Proxy APIs for web scraping is specialized scraping proxy systems that do not only take care of proxies but also takes care of headless browsers for you. Some proxy APIs go as far as helping out in handling Captcha

While regular proxies are priced either based on bandwidth usage or port, proxy APIs are priced based on the number of successful requests. They are quite useful when you want to delegate the tasks of managing proxies. They are effective in doing that as they make use of an IP rotation system that makes sure blocks are avoided.

Why You Should Use a Proxy API for Scraping

I don’t know about you, but I wouldn’t just rush into using a proxy API for all of my web scraping jobs until it is required. So, what are those reasons why people use them? Let take a look at a few of these reasons below.

Good for New Proxy Users

At first, you will have the thought that using proxies is an easy task, especially if you are carried away by the marketing gimmicks of proxy providers. However, when you start using proxies at a reasonable scale, you will get to know that proxy management is not an easy task. As a newbie in using proxies, you might things mixed up and get overwhelmed.

To avoid all of these, you can use proxy APIs as they are proxy newbie-friendly, When using a proxy API, you give URLs to those Scraping Proxy API, then get web page data back.

They are Equipped with Scraping Specialized Functions

One of the things that proxy APIs handle is headless browser automation, and you will agree with me that handling headless browsers yourself is not an easy task. You will appreciate this when you need to scale a headless chrome grid, which requires a lot of engineering time and knowledge – there’s also a financial cost attached to this. Some of the proxy APIs also have support for solving Captcha.

You only Pay for Successful Requests

One of the major reasons why you should use a proxy API is that the pricing is based on the number of successful requests. Because of this, the providers are always fine-tuning their system to increase their success rate. This makes a lot of sense and might be the reason they have a high success rate. However, you have to know that your subscription has an expiry date attached to it.

Best Proxy APIs for Web Scraping

There are many proxy APIs in the market optimized for web scraping. Most are paid while a few others have free plans with some limitations. We do not advise our users to use free proxy APIs as they won’t be effective and come with some disadvantages. For the paid ones in the market, below are the best 5 right now.

Downsides of Using Proxy APIs

While there is no doubt that proxy APIs are quite helpful to beginners, and when you do not want to worry about blocks and managing of proxy servers, they also have their downsides. Some of them are disclosed below.

They are Expensive

The number one downside to using proxy APIs is that they are expensive. While the cost is justifiable because it takes over the work of proxy management, handling browsers, and in some providers, Captcha solving, it is still expensive and can be termed over-priced. Take, for instance, sending 200,000 requests that will exhaust your $99 Crawlera Starter plan subscription. For some web scraping jobs, this plan will be exhausted in a few hours.

Content Returned Might Not Be What You Expect

One other problem associated with proxy APIs is that they might return the wrong kind of data. Take, for instance, some proxy APIs that have the problem of not returning images and videos. Some can even return the wrong data when it comes to geotargeted content. Because of this, it is advisable for you to make use of the provider's free trials first and see if it works as you want. Also, you can avoid some of these problems by encoding URLs correctly, using the wait parameter so JS codes will finish executing. Using premium_true = True can also help.

Privacy is of Major Concern

This problem is not only applicable to proxy APIs only. Any proxy network you use can monitor your traffic, and as such, the issue of data privacy can’t be ruled out. That’s is why you need to make sure you are using a trusted provider that has been proven beyond a reasonable doubt that it does not sniff on its users' traffic.

FAQs About Proxy APIs

Are There Free Proxy APIs in the market?

Yes, there are free proxy APIs in the market, but we always advise our users against using free proxy networks, and proxy APIs are not excluded.

Are Proxy APIs Unblockable?

Forget about what you hear; Proxy APIs are not unblockable. But to a large extent, they have proven to work better in avoiding blocks, and when it occurs, they have their ways around, such as in the case of handling Captchas. However, there are some cases that will still fail and report back to you after so many trials.

How Do Proxy API Providers Get Their Proxies?

Proxy API providers do disclose the source of their proxies. Some of them might be buying proxies from the regular proxy providers in the market while others build their proxy pools themselves. Whichever the case may be, you do not have to worry as you only pay for successful requests. And if you are unable to get them to work for you, you can simply ask for a refund.

Conclusion

Proxy APIs can help you avoid thinking of blocks and handling of browsers and Captcha. They serve as smart downloaders and will return a whole page for you with just an API call. Above are some of the best proxy APIs you can use for web scraping. However, be sure you are ready to spend more on them than you would on regular proxies.
