Problem with template and REST API

See if someone can help me with this:

Scenario: Raspberry Pi 3B + HA (supervisor) + HomeBridge + AppleTV.

Version: Home Assistant 0.114.4

I wanted to create a command_line (or more suitable) for a script (python) to run that gets a list of names.

Python name file: who_at_home.py (path /config/script/)

#!/usr/bin/python3
# -*- coding: utf-8 -*-

print( {"Enrique": True, "Carmen": False})

Show these names in a dictionary / JSON based HA template {Name: Property}

Enrique: True
Carmen: False

Expose the entity that executes the script through the HA REST API (I already have it operational and working, which is the REST API, activation of tokens, etc). But I don’t know the structure of the URL to consult the data and that it is returned in JSON. Maybe with json_attributes?

I would also be interested in showing that information in Home Apple as a list (it would be similar to the template). I suppose that if done right in HA it would already be replicated in Home Apple … Is that right?

Then using Siri Shortcuts I would like to consume said endpoint (I know how to do this).

Could someone help me with this? Any similar example?

sensor:
  - platform: command_line
    name: Who at Home
    json_attributes:
      - Enrique
      - Carmen
    command: 'python3 /config/scripts/who_at_home.py'
    value_template: '{% set value_json = value|from_json %}{{ value_json.state }}'
    scan_interval: 10
    command_timeout: 120

    - platform: template
      sensors:
        who_at_home_tempp:
          friendly_name: 'who_enrique'
          value_template: {{ value_json.Enrique }}'

All help is good.
Thank you very much!

I am interested in doing something similar. script, template and api exposure.
