API Resources

Server-side APIs allow developers to access data that companies and organizations provide through URLs, or endpoints. Developers can create applications that make requests to these endpoints, which respond with the requested data. Developers can then use this data in their own applications.

However, when you're building an application that only has a front end, you can only use APIs that don't require CORS. Cross-Origin Resource Sharing, also known as CORS, is a mechanism that allows a server to restrict which other origins other than its own are permitted to load resources.

For security reasons, browsers restrict cross-origin requests initiated from scripts. For example, the Fetch API follows the same-origin policy, which means that a web application can only request resources from the same origin the application was loaded from unless the response includes the right headers.

Therefore, when you're building a front-end application, you will need to use APIs that don't require CORS.
