Making Script Input URL

Who could please help me scripting a url input that only needs the below components? (schema.org)

  • Web page
  • Creativework
  • Organization
  • Person

(Actually the same idea as linter.structured-data.org)

So I would like to have a script that I can use in my own website and fill in the results according to my own idea with font and color.

So I only want to be able to check / read the structured data of a certain url.

Who would like to help me with that?
