Occasionally found this type of link (Google Fonts Previewer undocumented feature?) - search with query:
https://fonts.google.com/selection?query=some+search+text&selection.family=Archivo+Black|Asul|Cardo
It gives a list of fonts, but preview-test-text must be entered in the input box.
Is it possible to put custom text in URL (i.e. basically - to generate a preview with the link) to view how it looks in https://fonts.google.com/?
Maybe some kind of:
https://fonts.google.com/selection?query=search+text&selection.family=Archivo+Black|Asul|Cardo&preview=Some+Custom+Text+for+Preview
