About ExtendsClass JSON Storage

ExtendsClass JSON Storage is a service for storing and sharing JSON data (bins) over an HTTP API, with a web interface for creating and editing bins directly in the browser. Bins can be created without an account, but using the HTTP API requires a free account to obtain an API key. Each bin can be made public or private, and an optional security key can be set to protect a bin from modification and deletion.

The API supports creating, retrieving, updating (full and partial via JSON Merge Patch or JSON Patch), and deleting bins, along with listing all bin IDs associated with an account. Free usage is limited to 10,000 requests per month, a maximum bin size of 100 KB, and a 10 MB account quota.

The service is intended for developers who need a simple JSON data store for tutorials, sharing code examples, or mocking requests, as well as for use as a backend in websites and web or mobile applications during development and testing environments.
