What is an API? The waiter that connects all the software
You open the weather app and see the forecast for your city. That app doesn't have satellites, nor weather stations, nor a person looking out the window: it asks another system for the data. You request a trip on a transportation app and a map appears that the company didn't draw: it's the map of another service. You pay with a card in an online store that never touched...
An article discusses how Application Programming Interfaces, or APIs, act as intermediaries between different software systems, allowing them to communicate with each other. APIs enable apps to request data or services from other systems, such as weather forecasts or maps, without needing to know how they are generated. The article uses the analogy of a restaurant, where the API is like a waiter taking orders and bringing food from the kitchen, to explain how APIs work.
APIs have rules and security measures, such as API keys and rate limits, to ensure they are used correctly. The use of APIs is widespread, and they play a crucial role in modern software economy, including in open banking, government data, and artificial intelligence.
