Video summary

In this video, the speaker explains what APIs are and why they are needed. APIs, or Application Programming Interfaces, are contracts or protocols that dictate how different software applications communicate with each other. They allow for requests and responses between applications. APIs are necessary because they simplify communication between systems and reduce unnecessary work. The speaker uses analogies to illustrate the concept of APIs, such as changing a dinner reservation or using weather data from existing services. APIs work by using web APIs that deliver requests and responses usually over the internet using JSON or XML. Each API call consists of a server endpoint URL and a request method. The response body varies depending on the request, and it could be the server resource needed by the client or application-specific messages. The speaker also mentions the HTTP error code 404 when a URL is not found. To learn more about APIs, the viewer is encouraged to check out the linked article.
