I try to modify first page of laravel pagination from /category/german-language?page=1 to /category/german-language

also how to edit backend api path to frontend path

Current JSON

{ "first_page_url": "http://backend.example.com/api/category/slug/german-language?page=1",
            "from": 1,
            "next_page_url": "http://backend.example.com/api/category/slug/german-language?page=2",
            "path": "http://backend.example.com/api/category/slug/german-language",
            "per_page": "25",
            "prev_page_url": null,
            "to": 25}

Expected JSON

{
 "first_page_url": "http://frontend.example.com/category/german-language",
            "from": 1,
            "next_page_url": "http://frontend.example.com/category/slug/german-language?page=2",
            "path": "http://frontend.example.com/category/german-language",
            "per_page": "25",
            "prev_page_url": null,
            "to": 25}
