JSONbin.io

API

Free JSON storage service for small-scale web, mobile, and website projects

Overview

JSONbin.io offers RESTful endpoints for CRUD operations (create, read, update, delete) on JSON data. It supports storing lightweight JSON payloads, with responses always in JSON format. Ideal for small web apps needing temporary data persistence, mobile apps with minimal backend requirements, or static websites prototyping dynamic content without a full database. The service allows public bin access without authentication and uses API keys for write operations, making it simple to integrate into hobbyist or small-scale projects.
