如何设置Centris.ca API请求以获取英文响应？

背景 #

我正在学习一门课程，但课程内容已过时，目标房地产网站的部分内容发生了变更。获取房产数据需要调用两个API接口：

• 接口1：https://www.centris.ca/property/UpdateQuery
• 接口2：https://www.centris.ca/Property/GetInscriptions

目前遇到的核心问题是：找不到让这两个接口返回英文响应的方法。

已尝试的操作 #

• 请求头：设置Accept-Language: en-US,en;q=0.6
• Cookie检查：未发现与语言设置相关的Cookie项

       for listing in listings:
         print("not yet implemented")

补充说明 #

本次爬取的目标是网站的API接口，而非网页页面本身。
