Anyone have good examples of Terraform getting a remote json and assigning TF variables as a module to be consumed by multipe .tf projects?

Question

So I'm looking for some good examples of a module where I can remotely grab a json file and assign TF variables inside of a module to be consumed by several different terraform projects.

I'm new to TF and I know you can get he file like this:

module "get-my-json": {
   source="https://www.example.com/files/test.json"
}

but need some help in figuring out how to assign these to variables and for that module to be consumed by other tf projects.

Thanks
