APIs are essential for modern developers. They simplify complex tasks, help integrate features, and save time. But choosing the best API for developers can be overwhelming. Luckily, there are many options to get API free, including those offering free JSON API access. In this article, we’ll explore what makes an API ideal for developers and highlight some of the top free APIs available.
What is an API?
An API (Application Programming Interface) allows two systems to communicate with each other. It enables developers to use features like weather data, geolocation, or payment systems in their apps without building everything from scratch. APIs are especially useful for retrieving data in formats like JSON.
Why JSON APIs Are Popular
JSON (JavaScript Object Notation) is a lightweight and easy-to-use data format. Most APIs today use JSON because it is simple, fast, and compatible with multiple programming languages. A free JSON API can be incredibly helpful for developers who want efficient data handling without additional costs.
Features of the Best API for Developers
The best API for developers should include:
- Ease of Use: Simple documentation and fast implementation.
- Free Access: Ability to get API free for testing or small projects.
- Scalability: Options to upgrade as your needs grow.
- Performance: Quick response times and reliable uptime.

- Secure Your API Key: Keep your API key private to prevent unauthorized usage.
- Optimize Requests: Minimize the number of requests to improve performance.
Conclusion
Finding the best API for developers doesn’t have to be expensive. By leveraging options to get API free, you can access powerful tools for your projects. A free JSON API can simplify data handling, reduce costs, and speed up development. Choose wisely, test thoroughly, and unlock the full potential of APIs in your applications.
Consider that you are extracting products from flipkart and you also want to extract other 100 products from all the categories, however you are incapable to utilize this technique as it grabs the initial 15 products from the page.Flipkart is having a feature named infinite scrolling therefore there are no pagination (like?
In case, it had the feature we might have entered a value in the “while loop” as well as incremented page values like we have given below.page_count = 0while page_count < 5: url = "http://example.com?page=%d" %(page_count) # scraping code... page_count += 1 Now, let’s get back to the infinite scrolling.“Ajax” allows any website of using infinite scrolling.
However, the ajax request has the URL from which products gets loaded on the similar pages on scroll.To observe the URL.Open a page in the Google ChromeAfter that, go to a console and right click as well as allow LogXMLHttpRequests.Now reload a page as well as scroll down slowly.
While the new products get populated, you would see various URLs called after “XHR finished loading: GET” and click on it.
The one that you are searching for begins with “flipkart.com/lc/pr/pv1/spotList1/spot1/productList?p=blahblahblah_of_crap”Then left click on the URL and this would be highlighted within a Network tab of Chrome dev tools.
(here is the image)Whenever you open a link in a new tab then you would see something like that with about 15-20 products every page.You can observe that merely 15 products again!
