In the context of APIs, what does the term "transferable" primarily refer to?

The term "transferable" in the context of APIs primarily refers to the ability of data to be sent over networks. This concept is crucial in understanding how APIs facilitate communication between different software systems by allowing data to be exchanged seamlessly over the internet or other network types. Transferability ensures that data can travel efficiently from one server to another, making it accessible for applications or users that need to utilize that information.

This feature is fundamental in the design and function of APIs, which are intended to allow different systems to interact and share data dynamically. Without transferability, APIs would not fulfill their purpose of enabling interconnectivity between disparate systems and applications.
