API
A set of rules that allows different software systems to communicate with each other.
API
Overview
Modern software systems rarely operate in isolation.
Applications constantly exchange information with other applications, databases, cloud services, and AI systems.
One of the most common ways they communicate is through an API.
API stands for Application Programming Interface.
An API provides a standardized way for software systems to exchange information and request services from one another.
A helpful way to think about an API is a waiter in a restaurant.
Customers place orders.
The waiter delivers those orders to the kitchen.
The kitchen prepares the meal and sends it back.
Similarly, an API receives requests, communicates with a service, and returns a response.
Many modern AI systems are accessed through APIs.
Applications can send prompts to AI models and receive responses without needing to understand how the underlying system works.
APIs have become a foundational component of modern software development and AI deployment.
Why It Matters
APIs make it possible for applications and AI systems to work together.
Real-World Example
A customer support application may use an AI API to generate responses for support agents.
