Do I need to create the 'store/carts' endpoint or it already comes when i install Medusa?

I'm trying to implement an "Add to cart" functionality. While I know how to add, delete and update a cart based on the docs, the functions do not work because all the cart endpoints do not exist. Accessing 'http://localhost:9000/store/carts' on the browser shows "Cannot GET /store/carts"
