API not working as expected

When I include this address in the address bar http://localhost:1337/api/pages?slug= I am expecting to not see any data come through the api as I have only one page content type with the slug of ‘home’, However, all the page content type content is being returned!

Also, no block content is being returned from the api as is expected from the blocks that were set up in the page content type dynamic zone.

Why isnt this working?
