    ? action        = query
    & format        = json

                "pageid": 77085108,
                "ns": 10,
                "title": "Template:POTD/2024-06-06",

    "query": {
        "pages": [

                        "ns": 6,
                        "title": "File:NNC-US-1849-G$1-Liberty head (Ty1).jpg"
                    },
                    {
