Statelessrajapinnat, often translated as stateless APIs, are a fundamental concept in web service design. They operate based on the principles of REST (Representational State Transfer), a set of architectural constraints for distributed hypermedia systems. The core characteristic of a stateless API is that each request from a client to the server must contain all the information necessary to understand and complete the request. The server does not store any client context or session state between requests.

This lack of server-side state has several significant advantages. Firstly, it greatly enhances scalability. Since the server doesn't need to manage individual client sessions, it can handle a much larger number of concurrent requests. Each request is independent, allowing for easier distribution across multiple servers. Secondly, statelessness improves reliability. If a server fails, another server can seamlessly take over without losing any client information, as that information resides with the client.

Thirdly, stateless APIs simplify the client-server interaction. Clients are responsible for maintaining their own state and sending it with each request. This can involve passing tokens, cookies, or other identifiers in the request headers or body. While this places more burden on the client, it leads to a cleaner and more decoupled architecture. Examples of stateless APIs are prevalent in modern web development, powering everything from mobile applications to single-page web applications.
