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.</p>
<p>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 <a href="https://www.bestproxyreviews.com/proxy-pool/">proxy pool</a> &ndash; you wouldn&rsquo;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.</p>

<h2 style="text-align: center;"><strong>What is a Proxy API for Scraping?</strong></h2>
<p><img class="aligncenter size-full wp-image-4104" src="https://www.bestproxyreviews.com/wp-content/uploads/2020/04/API-for-Scraping.jpg" alt="API for Scraping" width="700" height="443" /> 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.

<p>While regular proxies are priced either based on bandwidth usage or port, proxy APIs are priced based on the number of successful requests.

<h2 style="text-align: center;"><strong>Why You Should Use a Proxy API for Scraping</strong></h2>
<p><img class="aligncenter size-full wp-image-4102" src="https://www.bestproxyreviews.com/wp-content/uploads/2020/04/Proxy-API-Scraping-uses.jpg" alt="Proxy API Scraping uses" width="1007" height="523" /> I don&rsquo;t know about you, but I wouldn&rsquo;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.</p>
<ul>
<li>
<h3><strong>Good for New Proxy Users</strong></h3>
</li>
</ul>
<p>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.</p>
<p>To avoid all of these, you can use proxy APIs as they are proxy newbie-friendly, <strong>When using a proxy API, you give URLs to those Scraping Proxy API, then get web page data back.</strong></p>
<ul>
<li>
<h3><strong>They are Equipped with Scraping Specialized Functions</strong></h3>
</li>
</ul>
<p>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 &ndash; there&rsquo;s also a financial cost attached to this. Some of the proxy APIs also have support for solving Captcha.</p>
<ul>
<li>
<h3><strong>You only Pay for Successful Requests</strong></h3>
</li>
</ul>
<p>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.</p>

<h2 style="text-align: center;"><strong>Downsides of Using Proxy APIs</strong></h2>
<p><img class="aligncenter size-full wp-image-4106" src="https://www.bestproxyreviews.com/wp-content/uploads/2020/04/Downsides-of-Using-Proxy-APIs.jpg" alt="Downsides of Using Proxy APIs" width="978" height="489" /> 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.</p>
<ul>
<li>
<h3><strong>They are Expensive </strong></h3>
</li>
</ul>
<p>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.</p>
<ul>
<li>
<h3><strong>Content Returned Might Not Be What You Expect</strong></h3>
</li>
</ul>
<p>One other problem associated with proxy APIs is that they might return the wrong kind of data. Take, for instance, <strong>some proxy APIs that have the problem of not returning images and videos</strong>. 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.</p>
<ul>
<li>
<h3><strong>Privacy is of Major Concern</strong></h3>
</li>
</ul>
<p>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&rsquo;t be ruled out. That&rsquo;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.</p>
<hr />
<h2 style="text-align: center;"><strong>FAQs About Proxy APIs</strong></h2>
<hr />
<ul>
<li>
<h3><strong>Are There Free Proxy APIs in the market?</strong></h3>
</li>
</ul>
<p>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.</p>
<hr />
<ul>
<li>
<h3><strong>Are Proxy APIs Unblockable?</strong></h3>
</li>
</ul>
<p>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.</p>
<hr />
<ul>
<li>
<h3><strong>How Do Proxy API Providers Get Their Proxies?</strong></h3>
</li>
</ul>
<p>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.</p>
<hr />
<h2><strong>Conclusion</strong></h2>
<p>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.</p>
