APIs allow developers to access the data and functionality of a service or resource without requiring in-depth knowledge of its implementation. By defining CRUD (Create, Read, Update, Delete) operations, an API enables applications to interact with the service or resource.

For example, the data might be structured in JSON as follows:

– Product 1: ID 1, name “Product 1”, description “This product is awesome!”, price 100
– Product 2: ID 2, name “Product 2”, description “This product is even more awesome!”, price 200

Methods associated with this data include:
– GET /products/:id: to retrieve a product based on its ID
– POST /products: to create a new product
– PUT /products/:id: to update an existing product
– DELETE /products/:id: to delete an existing product
