Which of the following is NOT a common type of API?

• A. REST
• B. SOAP
• C. XML-RPC
• D. GraphQL

Answer: (C)

XML-RPC is considered less common today compared to the other options listed. While it is a protocol that allows remote procedure calls using XML to encode its calls and HTTP as a transport mechanism, it has largely been overshadowed by more modern and flexible alternatives. REST, SOAP, and GraphQL are widely adopted approaches in API design for various reasons. REST provides a stateless architecture that uses HTTP and is easy to understand and implement, making it a popular choice for web services. SOAP, although it is more rigid and complex due to its reliance on XML and strict standards, is still widely used in enterprise environments where formal contracts and security standards are crucial. GraphQL introduces a flexible query language for APIs, allowing clients to request only the data they need, which leads to improved efficiency and performance. In contrast, XML-RPC is not commonly used in contemporary API design discussions, as developers favor more modern paradigms that offer better performance, flexibility, and ease of use.
