How to get Page Builder widgets used in Json

Hi All,

I have just started using Page Builder for the first time and so far I think it is awesome. I starting a new project where I am using a headless WP site on top of a React.js application.

What I am hoping to do is using Page Builder to allow users to build pages in the CMS, then I would like to feed the widgets and their information to the page JSON data. Then I can drop the data into my custom build React modules on the front end. I am hoping for something like this:

{
  "id": 21,
  "slug": "hello-world",
  "pageBuilder": {
    "rows" [{
      "Columns": 2,        
      "widgets": {
        "image": {
          "imageTitle": "This is the image title",
          "imageUrl": "This is the image title"
        },
        "text": {
          "title": "This is the text title",
          "content": "This is the content of text widget"
        }
      }
    },
    {
      "Columns": 2,        
      "widgets": {
        "image": {
          "imageTitle": "This is the image title",
          "imageUrl": "This is the image title"
        },
        "text": {
          "title": "This is the text title",
          "content": "This is the content of text widget"
        }
      }
    }]        
  }
}

This is some very basic JSON I quickly wrote just now, I am sure the actual solution would be much better.

If anyone knows if this exists and how I can access it please let me know.

Thanks in advance for any help,
Luke.
