Application Programming Interface

Definition ∞ An Application Programming Interface, or API, is a set of defined routines, protocols, and tools for building software applications. It specifies how software components should interact, enabling different systems to communicate and exchange data. In crypto, APIs allow external applications to access blockchain data or interact with decentralized services.
Context ∞ APIs are fundamental for the integration of blockchain technology with traditional financial systems and for the creation of sophisticated decentralized applications. A key discussion point involves the security vulnerabilities associated with API endpoints and the standardization of APIs for various blockchain protocols. Future advancements will likely center on developing more robust, secure, and interoperable APIs for Web3 infrastructure.
