API

Definition ∞ An API, or Application Programming Interface, is a set of rules and protocols that allows different software applications to communicate with each other. It functions as an intermediary, enabling data exchange and functionality access between disparate systems without requiring direct knowledge of their internal workings. APIs are fundamental for building interconnected digital services.
Context ∞ In the cryptocurrency domain, APIs are critical for exchanges to provide trading data and order execution capabilities, for wallets to interact with blockchains, and for decentralized applications to access on-chain information. Ongoing developments in API security and standardization are key considerations for developers and users interacting with digital asset platforms.
