As a developer, there are many instances where you’ll need to use an API. From building a simple portfolio project or a prototype to building robust real-time applications.

APIs saves us the hustle of reimplementing a logic by simply providing an interface to help with the functionalities we wish to have in our application.

Here are five APIs that I love and I think you should try them out.

1. JSON Placeholder API.

The JSON placeholder API is a RESTFUL API for fake content. It’s a go-to API if you need to make a quick prototype for a blog or website. From this API, you can get data for posts, comments, users etc.

Features of the API:

• Endpoints to make CRUD operations.
• Free to use.
• No keys are required.

2. Fakestore API.

Like JSON placeholder it provides fake content but is more tailored for e-commerce prototypes. You can fetch product data, reviews, and more from their restful endpoints.

Features of the API:

• REST endpoints to make CRUD operations.
• Free to use.
• No keys are required.

3. Auth0.

Auth0 is a platform for user authentication and authorization. It provides an easy interface to implement authentication methods like multifactor authentication, social logins, and even authorization to backend services.
