如何用Python获取网页Preview中的JSON数据？API遇Cannot GET错误

我在查看基金网页时，通过浏览器开发者工具能看到一个名为“execute”的JSON接口返回了目标数据，但直接访问该API地址时，页面提示“Cannot GET /execute”错误。我推测这和token、密钥或API权限有关，作为新手想知道有没有办法用Python获取这些已经在网页上公开展示的数据，或者如何获取合法访问权限。数据已经在网站上显示了，理论上应该能获取，但我不知道具体方法。参考相关案例后，我尝试了以下代码，但无法正常运行：

import requests


payload = {
    "value": {
        "queries": [
            {
                "key": "nav_price_evolution_filtered",
                "type": "arrayOfObjects",
                "valid": True,
                "columns": [
                    {"name": "date", "nameTranslated": "date"},
                    {"name": "date_month_year", "nameTranslated": "date_month_year"},
                    {"name": "nav_price", "nameTranslated": "nav_price"},
                    {"name": "aum_size", "nameTranslated": "aum_size"},
                    {"name": "month_year", "nameTranslated": "month_year"},
                    {"name": "total", "nameTranslated": "total"},
                    {"name": "startDate", "nameTranslated": "startDate"},
                    {"name": "endDate", "nameTranslated": "endDate"},
                    {"name": "currency", "nameTranslated": "currency"}
                ],
                "results": [
                    {
                        "date": "22/05/2024",
                        "date_month_year": "05-2024",
                        "nav_price": 100.1215,
                        "aum_size": 458439516.26,
                        "currency": "EUR",
                        "endDate": "2024-05-22",
                        "month_year": "May 2024",
                        "startDate": "2002-12-20",
                        "total": 5101
                    },
                ]
            }
        ]
    }
}


api_url = "https://api-eu.kurtosys.app/dataset/execute"
headers = {
    "x-api-key": "b5954b1e-2cfa-453f-b336-75557f19ffae",
    "Origin": "https://fonds.axa-im.fr/fr/professionnels/fund/axa-pea-rgularit-capitalisation-eur/#performanceRisk",
}

data = requests.post(api_url, headers=headers, json=payload).json()
print(data)
