3. 💡 解决方案

import requests

url = "https://api.example.com/your-endpoint"
headers = {
    # 移除"anthropic-beta"请求头，仅保留其他必要的请求头
    "Authorization": "Bearer your-token",
    "Content-Type": "application/json"
}
payload = {"your": "data"}

response = requests.post(url, headers=headers, json=payload)
print(response.json())

#### 方案二：将请求头值改为服务端允许的合法值
先查阅文档确认anthropic-beta请求头的合法取值（如特定版本标识），再修改为合法值，示例如下：

import requests

url = "https://api.example.com/your-endpoint"
# 将值替换为文档中允许的合法取值，例如"2023-10-31-beta"
headers = {
    "anthropic-beta": "2023-10-31-beta",
    "Authorization": "Bearer your-token",
    "Content-Type": "application/json"
}
payload = {"your": "data"}

response = requests.post(url, headers=headers, json=payload)
print(response.json())
