Automation to run specific URL at 5:00 pm

I need to create an automation to run/check a specific URL at a specific time. What is the best service I could use?

- id: 123456789
  alias: "Check URL"
  trigger:
    platform: time
    at: "17:00:00"  

  action:
    - service: call a service to check https://www.mysite.com


Thanks in advance for your help.
