ExtendsClass JSON Storage is a development API described as: A simple JSON store API. It is useful when you need programmatic access to a simple json store api from applications, dashboards, or internal tools. The published entry point or documentation is hosted at extendsclass.com, which makes it a practical starting point for evaluating available endpoints and response formats. Because the listing indicates no authentication, it is comparatively easy to test for prototypes, demos, or lightweight integrations.
