Add dynamic assign limiter to get_data function.
From my previous experience, the APIs are:

1. One rate limit to all functions.
2. Some functions are in A-rate, the others in B-rate.

By the way, the idea of the context manager is a good idea in some cases. In my case, I need to login to use the API, it might suitable for the singleton pattern. But in other case which no need of sharing setting, the context manger version will be a good usage.
