Publicly available Postman collection with query parameter for locales

Question

I need some advice about how to create publicly available Postman collection with query parameter. The data would be fix, something like:

{
  "home": {
    "title": "Hello"
  }
}

and the url would be created by Postman, e.g. https://api.postman.com/translations/titles/en

If I use https://api.postman.com/translations/titles/fr the data would be:

{
  "home": {
    "title": "Bonjour"
  }
}

Is it possible somehow? If not with Postman, what free service do you suggest?
