# Web Scraping vs. APIs: Which is Best for Data Extraction?
![Web Scraping vs. APIs Which is Best for Data Extraction (1)](https://hackmd.io/_uploads/HJgcgh7ple.png)
In the ever-growing era of data collection, there are two distinct approaches that are trending most of the time. One is Web Scraping, and the other is APIs. These techniques are the most essential for businesses or developers. Each method has its pros and cons.  Businesses today extract data from any website using web scraping or official APIs. In this article, we will understand the intricacies and simplicity of Web Scraping and API, and how they differ from each other. This will help you choose the right one for your next data scraping project.
## What is Web Scraping?
Web scraping literally means a bot or crawler that can be used to extract publicly available data from any website. Based on what you want for your business, a scraper can be customized to extract images, text, video, or [B2B data](https://www.locationscloud.com/b2b-data/). Basically, web scraping converts raw HTML data or unstructured data into a more structured and understandable format.
**Web scraping works in the following manner:**
First of all, you will make an HTTP request to web Servers. Next, you have to download the HTML content of the website you wish to scrape data from. Now, parse this HTML data to pull out the needed information. Web scrapers can visit multiple pages, handle different data formats, and sometimes even interact with dynamic JavaScript. This functionality makes them perfect for collecting valuable data.
## Features of Web Scraping
These are some of the important features of web scraping that you need to consider before scraping data.
●     Enables you to access publicly available data with no restrictions.
●     Provides complete control over data scraping timing and frequency.
●     Helps you seamlessly collect data from more than one source simultaneously.
●     You can easily schedule data collection according to your desire.
●     Allows you to extract historical data.
## What Are APIs?
APIs (Application Programming Interface) are a mechanism that enables computers or software to communicate with each other. It basically works as an intermediary that allows developers to access or use data from other software applications without any hassle. API offers a more generic way for applications to exchange information.
**Let’s see how APIs work:**
First, identify the endpoints that your targeted website uses. After this, you have to understand its specification. Wait for the API response. It will be in XML or JSON. Next, you need to pass the response to extract the desired data. Once this is done, you can finally process, filter, or store data in any spreadsheet or database. Because API rely less on HTML structure, they provide more accurate and structured data.
**Features of API**
The following are the major features of API you have to consider when scraping data. 
●     It provides a high level of security through authentication and authorization.
●     APIs have built-in functionality to balance load.
●     Provides simplicity in response formats.
●     Easily monetized to gain its advantage.
●     APIs can be used by developers to extend their functionality.
●     Helps you automate repetitive tasks.
Web scraping and API can be used to extract data from any website. However, they differ in many ways. So, let’s understand this difference in depth.


| Criteria  | Web Scraping | API |
| -------- | -------- | -------- |
| Access     | It has a risk of being blocked by websites' anti-bot systems    | Restrictions are based on usage and paid plans.
Stability     | Highly dependent on fluctuations in website structure and anti-scraping measures         | It is stable with a version control facility
Coverage     | Data can be extracted from any public website     | Scope is limited to websites offering API endpoints
|Data Format     | Basic HTML requiring parsing and cleaning     | Requires structured data such as JSON/XML
Cost     | Includes the cost of proxy and Infrastructure     | Depending on the purchased API plan.
| Legality     | Targeted website terms & conditions must be considered     | Clear usage terms and conditions     |
Speed     | Slow for scraping a vast amount of data     | It is fast because of direct data accessibility 
Technical Setup     | Requires custom scraping logic and maintenance     | Direct integration with documentation 

Let’s analyze the above difference in detail so that you can select the approach for your project.
**APIs Have the Ability To Manage Anti-Bot Systems Compared to Web Scraping**
You may encounter some challenges from the anti-bot system, which cannot be neglected. If you want to overcome them, then you have to go for proxies or headless browsers for a seamless process. In contrast, APIs have a straightforward approach with authenticated access through API keys. Here, you have to strictly follow the rate limit and usage policies.
**APIs Offer Better Stability Compared to Web Scraping**
Web scrapers are not able to bear website changes and updates. Changes in HTML structure can break your code, hence it requires maintenance. API, on the other hand, provides a stable environment with versioning support; however, it may deprecate this feature.
**Web Scraping Can Be Cheaper Compared to APIs:**
Web Scraping involves infrastructure and maintenance. You have to pay for proxies and servers for scale and frequency of operations. While the API price is based on usage, it can be expensive if you have to collect a high volume of data.
**APIs Provide Structured Data Compared To Web Scraping**
Web scrapers heavily depend on unstructured HTML; therefore, you need to process it further. You then need to parse, clean, and convert data into a more structured format. While API offers data in an understandable JSON and XML file format. Then you have to just load both files, navigate their structure, and extract the needed data
**APIs Are Safer Than Web Scraping**
Web scraping accepts only public data. You have to consider the targeted website's terms and conditions or follow the ideal practice for web scraping. As opposed to it, APIs offer a clear legal framework of their terms and conditions. APIs are a safer way to scrape website data than a Web scraper.
**APIs Are Faster Compared to Web Scraping**
Web Scraping is sluggish, especially when you have to extract large-scale data from JavaScript-enabled websites. In contrast, APIs can optimize data delivery with less overhead; therefore, they perform faster in most cases. If you have to use web scraping, then you should look into the ways to either efficiently handle requests or parallel processing.
**Web Scraper Development Requires Technical Knowledge Than APIs**
Developing your own web scraper can be a tough nut to crack because it requires lots of technical expertise, not only in understanding the structure of a web page, but also in security measures and parsing logic. API generally provides clear documentation with simple integration patterns that can be understood by developers of all skill levels.
## What to Choose: Web Scraping or APIs?
**Choose an API when:**
●     You need structured data.
●     Official API is available to serve your data extraction purpose.
●     You want to integrate it into an existing system without technical       requirements.
●     Legal consideration is pivotal.
●     You are seeking stability with version control.

**Choose Web Scraping when:**
●     You have to extract data in a custom format.
●     There are no official APIs.
●     You have a limited budget.
●     Working with an immense amount of unstructured data.
●     You have technical expertise.
## Future Trends
In the near future, browser-based web scraping will become more pivotal as websites are using JavaScript and dynamic content. You will need a tool that can directly interact with modern web applications.

API integration, along with AI, will boom in areas where businesses have to extract intelligent content from unstructured data and can handle frequent website changes. In a nutshell, we can say that the debate of the difference between Web scraping and API leans towards the usage of AI in APIs.

Furthermore, scraping any data ethically will become more pivotal to web scraping.[Web scraping service providers](https://www.iwebscraping.com/) have to follow emerging concerns, such as rate limits and adhering to robots.txt.

## Conclusion
In this blog post, we learn what web scraping and API is. We understand the features of both, how they work, and how they differ from each other. You have to use the API when you need both reliable and real-time data, or ready-to-use structured data. On the other hand, you can utilize web scraping when a website doesn’t have official APIs. If you are looking for a flexible option in accessing publicly available data, then web scraping is a better option to choose. Web scraping and API have their own upside and downside. Though web scraping and API can help you to scrape data from websites, it's good that you think logically and choose one based on your project, or combine both.
