Overview
ExtendsClass JSON Storage is a web-based utility designed to provide a simple, ephemeral, or persistent backend for JSON data. It enables developers to store, retrieve, update, and delete JSON objects using a straightforward HTTP REST API. The service is particularly suited for scenarios where a lightweight data store is needed quickly, such as during the development and testing phases of an application, for proof-of-concept projects, or for hosting small, static datasets without the overhead of setting up and managing a traditional database.
The platform differentiates itself by requiring no authentication for public data bins, which streamlines the setup process for rapid development. This design choice makes it accessible for front-end developers who need a quick mock API or for educational purposes where complex authorization flows are not desired. For more controlled access, private bins can be created, which are only accessible via a unique URL. Data stored within JSON Storage can be managed through a web interface, allowing users to view, edit, and delete their JSON documents directly.
ExtendsClass JSON Storage supports standard CRUD (Create, Read, Update, Delete) operations, making it compatible with common web development patterns. Developers can use any HTTP client or programming language to interact with their stored JSON. The service manages the underlying storage and retrieval mechanics, abstracting away database configuration and maintenance. This focus on developer experience means that users can concentrate on their application logic rather than backend infrastructure. Its utility extends to scenarios like storing user preferences for simple apps, managing content for static sites, or serving as a temporary data layer for interactive prototypes.
While the service offers a free tier suitable for minimal usage, paid tiers are available for increased storage capacity and higher request volumes. This scaling model allows it to accommodate projects from individual developers to small teams requiring more substantial resources. The primary objective of ExtendsClass JSON Storage is to reduce the friction associated with data storage, offering an immediate solution for JSON data management.
Key features
- RESTful API Interface: Provides standard HTTP methods (GET, POST, PUT, DELETE) for interacting with JSON data, enabling seamless integration with web applications and scripts (ExtendsClass JSON Storage API reference).
- No Authentication for Public Bins: Allows for quick setup and testing without the need for API keys or user logins for publicly accessible data.
- Private Bins with Unique URLs: Offers a level of data isolation for sensitive or specific project data, accessible only via a unique, non-guessable URL.
- Web-based Management Interface: Users can view, edit, and delete their JSON documents directly through a browser-based dashboard.
- CRUD Operations: Full support for creating new JSON objects, reading existing data, updating specific fields, and deleting entire documents.
- Data Persistence: Stored JSON data persists across sessions, suitable for dynamic content or application settings.
- Scalable Storage and Requests: Offers tiered plans to accommodate varying data storage requirements and API call volumes, from free basic usage to paid enterprise-level capacity.
- Automatic Schema-less Storage: No predefined schema is required, allowing for flexible data structures that can evolve with application needs.

Common integrations
ExtendsClass JSON Storage, with its straightforward REST API, can be integrated into virtually any application that can make HTTP requests. Common integration patterns include:
- Front-end Web Applications: Used with JavaScript frameworks like React, Angular, or Vue.js to store and retrieve application state, user preferences, or small content blocks.
- Mobile Applications: Employed by iOS and Android applications written in Swift, Kotlin, or React Native for simple data storage that doesn't require a full cloud backend.
- Command-line Tools and Scripts: Integrated into Python, Node.js, or Shell scripts for managing configuration files, logging data, or automating small data tasks.
- Static Site Generators: Provides dynamic content for frameworks like Jekyll, Hugo, or Gatsby, allowing for content updates without redeploying the entire site.
- Testing and Mocking Environments: Serves as a mock API endpoint for unit and integration testing of applications that consume external data. Similar services like MockAPI also offer this capability.
Alternatives
- JSONPlaceholder: A free fake online REST API for testing and prototyping, primarily for GET requests, providing predefined sets of data.
- MockAPI: A tool for creating custom mock REST APIs quickly, allowing users to define their data models and endpoints.
- JSONBin.io: Offers a free JSON storage service with a REST API, supporting private bins and version control for JSON data.
Getting started
To get started with ExtendsClass JSON Storage, you can create a new JSON bin and then interact with it using simple HTTP requests. Here's an example using JavaScript's fetch API to perform a POST request (create data) and a GET request (retrieve data).
First, create a new JSON bin on the ExtendsClass JSON Storage website. Once created, you will receive a unique bin ID (e.g., your_bin_id).
const binId = 'YOUR_BIN_ID_HERE'; // Replace with your actual bin ID
const apiUrl = `https://api.extendsclass.com/json-storage/bin/${binId}`;
// --- POST: Add new data to the bin ---
const newData = {
"productName": "Wireless Mouse",
"price": 25.99,
"inStock": true,
"sku": "WM-001"
};
fetch(apiUrl, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(newData),
})
.then(response => {
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
return response.json();
})
.then(data => {
console.log('Data added successfully:', data);
// --- GET: Retrieve all data from the bin after adding ---
return fetch(apiUrl)
.then(response => {
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
return response.json();
});
})
.then(retrievedData => {
console.log('Retrieved data:', retrievedData);
})
.catch(error => {
console.error('Error:', error);
});
This code snippet first sends a POST request to add a new product object to your specified JSON bin. Upon successful creation, it then performs a GET request to retrieve all the data currently stored in that bin, printing both the successful POST response and the full bin content to the console. Remember to replace 'YOUR_BIN_ID_HERE' with the actual ID generated for your bin on the ExtendsClass website.
