A JSON API is an application programming interface that uses JSON to exchange structured data between software systems. It allows applications to send requests and receive responses containing information in a simple, standardized format, often over HTTP. A client can request specific data or actions, while the server processes the request and returns a JSON response. This approach helps different applications communicate even when they are built using different technologies.
For example, a weather application can use a JSON API to request current weather information from a remote service and receive details such as temperature, conditions, and location data. JSON APIs are widely used in websites, mobile applications, cloud services, e-commerce platforms, and connected devices. They simplify system integration, support automation, and enable flexible data exchange between applications.
