Hello, I have been tasked to attempt usage of Baidu Yuyin and UNIT for robot development. As of now, I require the capability to retrieve weather information, with multi-country support being something sought after, as well as the ability to perform an encyclopedia search using something like Baike.

As such, I am obliged to check if there are any open source weather information and Baike/Encyclopedia APIs under Baidu which we could use, so as to provide a usability showcase to our supervisor. Your feedback will be most appreciated.

您好， 我正在开发一个对话机器人， 测试着百度的语音与UNIT服务。我所要试的功能包括领取各国的天气预报和搜寻功能。

因此，我想知道百度是否有提供天气预报和百度百科的API服务。
