ZennApi is a service that provides various kinds of APIs for free. No registration, credit card, or personal data needed.
APIs are mechanisms that enable two software components to communicate with each other using a set of definitions and protocols.
API architecture is usually explained in terms of client and server. The application sending the request is called the client, and the application sending the response is called the server.
APIs are essential for modern applications as they enable different systems, services, and applications to communicate seamlessly. They provide a standardized way for applications to request and access data, services, or functionality from other applications or systems.
