JSON APIs allow applications to exchange data in JavaScript Object Notation (JSON) format, making them lightweight, human-readable, and widely supported. They are commonly used in RESTful services for CRUD operations over HTTP.
Example with a Public Test API (JSONPlaceholder) JSONPlaceholder provides fake endpoints for prototyping:
GET /posts – List all posts
GET /posts/1 – Get a single post
POST /posts – Create a new post
PUT /posts/1 – Replace a post
PATCH /posts/1 – Update part of a post
DELETE /posts/1 – Delete a post
JavaScript Example – GET Request
// Fetch a single postfetch('https://jsonplaceholder.typicode.com/posts/1').then(response => response.json()) // Parse JSON.then(data => {console.log('Post Title:', data.title);console.log('Post Body:', data.body);}).catch(error => console.error('API Error:', error));Copied!✕CopyPython Example – GET Request
