In the 21st century, everything tends to circle back to technology. This has further resulted in an ample amount of data that needs to be researched, analyzed, and extracted. And that is exactly when two major data extraction tools—API (Application Programming Interface) scraping and web scraping—come into play.

They are often believed to be two sides of the same coin. They have been gaining ground among the data extraction community for quite a while now. While some believe API scraping to be superior to web scraping, others think of it as a factually incorrect statement.

Through this article, we will put both theories to the test and determine the better data extractor among these two.

What does API scraping mean?

It refers to the process of extracting and accessing data from different websites or operating systems using APIs (application programming interfaces). Unlike web scraping, it fetches the data from the website’s backend by using an application programming interface (API).

Furthermore, these tools present the data in a machine-readable format, making it an efficient and convenient source.

Some of the commonly used API scraping tools are mentioned below:

The extracted data can then be used to generate leads, monitor prices and trends for research, etc.

Workings of API scraping

    • Initial Request: The initial step includes locating the API endpoints that provide the required data. Furthermore, it involves analyzing the processed data using API discovery tools.
    • Authentication: Several authentication tools, like API keys, come into play to ensure secure communication between the requester and server.
    • Acquiring data: After authenticating, the requested data is then processed and presented by the API server in JSON or XML format.
    • Data Storage: The extracted data is then saved as CSV or JSON file, or in a database.

Pros and cons of API scraping

This tool offers several advantages over traditional scraping tools. Some of the key advantages are mentioned below:

  • Maintainability: APIs used in the process of API scraping are comparatively more stable and less susceptible to changes. Thus, reducing the resources utilized in its maintenance.
  • Real-time data: It extracts data via API directly from the websites, resulting in near-instantaneous access to the latest information. This further proves advantageous in market monitoring, financial trading, and news aggregation.
  • Legality: APIs request permission beforehand from websites, thus avoiding any kind of legal trouble.
  • Scalability: It uses various techniques to deal with the extraction of data. This makes it possible to handle large sets of data without much difficulty.

Like any other scraping tool that is out there, API scraping too has its fair share of disadvantages. Some of the main downsides are mentioned below:

  • Limited access: It tends to have limited access in terms of the free features available. There is a great possibility of crucial data being omitted and made available only after further payments.
  • Limited API requests: The API provider puts a limit on the number of API requests a server can make in a given period. This imposes a major hindrance, especially in the case of the scalability of data.
  • Absence of API endpoints: Not all the websites contain API endpoints. The lack of these endpoints obstructs the process of API scraping.
  • Quality of data: While using this tool, the quality of the data extracted depends on the API itself. Errors in the API can thus affect the data quality as well.

What does Web Scraping mean?

It refers to the process of extracting data from a given website or operating system, either manually or by using software tools. The software tools used to extract data are known as web scrapers.

Some commonly used web scrapers are mentioned below:

  • Python

The extracted data can then be used for different purposes, such as research, market analysis, news monitoring, lead generation, etc.

Working on Web Scraping

The workings of web scraping can be summarized in the steps stated below:

  • Requesting Data: Different HTTP commands like GET, POST, and PUT are used to extract, submit, and update data on a website.
  • Data Parsing: The data obtained is then processed and presented in a more comprehensible and structured format to the user, known as data parsing. There are a wide variety of formats to choose from, like XML, JSON, etc.
  • Data Storage: The data obtained is then stored in different formats (CSV, JSON, XML, and databases) depending on its size and type.

Pros and Cons of Web Scraping

There are several reasons why this tool is beneficial to the user, some of which are stated below:

  • Cost-effective: It is considered to be cost-effective. These tools available extract the data from different websites free of charge, enabling users to avoid hiring people to do that manually.
  • Time Efficiency: These tools extract, process, and present the data in a presentable manner within a record time, saving the user his efforts and time.
  • Result Accuracy: These tools know and use the right tools and techniques to collect data that is up-to-date and highly accurate. This is something that can’t be ensured entirely when done manually.
  • Lead Generation: These tools are known for analyzing trends and making effective future predictions. This feature, backed by accurate results, helps generate leads.

While there might be several facts as to how and why this method is beneficial for users, we can’t turn a blind eye to its impacts on users and digital words as well. Below are some of the drawbacks:

  • Legality Issues: This method is considered illegal in cases where the websites prohibit it by stating the same in their terms of service agreements. Websites may also block these tools, making things difficult.
  • Error Prone: It comes with its fair share of risk. These tools on a large number of websites increase the risk of errors and require a lot of computing power and bandwidth.
  • Maintenance issues: For these tools to operate properly, regular maintenance and updates are a must. This turns out to be tiresome and exhausting, making it difficult to operate effectively.
  • Input costs: Even though this method is cost-effective as compared to manual data collection, it isn’t exactly cheap. Input costs in the form of hardware, software, and staffing still need to be made.

Web Scraping and API Scraping: Similarities

The first and foremost fact is that both the tools are widely known for efficient data extraction. They are proving to be beneficial for the economy as a whole. Both methods require technical knowledge for efficient working and require input costs to be made.

Furthermore, despite following different processes, both tools extract useful data.

Web Scraping and API Scraping: Differences

Both web and API scraping are the best tools that the market has to offer, and their differences only make them better than the rest.

The most significant difference between both the tools is the process of extracting data. Web scraping extracts data from various websites or software, either manually or by using software tools. On the other hand, API scraping extracts data from different sources using API endpoints.

The access to information in both tools differs. While the web scraping tool accesses data from all websites, API scraping faces some difficulty, especially when a website restricts API exposure.

Furthermore, web scraping would be deemed illegal if the terms of the website condemned it. But it isn’t the same for API scraping.

What does Web Scraping API mean?

With the vast variety of data available on the market, a tool with the combined benefits of both the tools discussed above was the need of the hour.
