How to call API on WeChat public platform?

Just recently, we are developing the WeChat public platform. Let's talk about what functions the WeChat public platform can achieve (except basic reply):

1. Common API calls: weather query, peripheral search, ranging, map navigation, artificial intelligence funny reply, translation, express query, daily jokes, real-time news, football scores, etc.

2 code realization: you can engage in spike activities, scratch music, video playback, membership binding and so on. Of course, what shocked me is that the game can be developed on the WeChat public platform and is still under development.
