Ask HN: When is client module needed for a REST API service?

I run a weather service that allows REST API access to time-series weather data (historical & forecast).

I've tried to make it as intuitive as possible without too much abstraction, where the query basically answers the questions where you'd like the data for (location), for what time period (start, end dates), and what weather parameters (temperature? wind speed? etc.) they might be looking for:

General feedback is that the API is easy to use. However, I do have developers who go silent during multi-day email conversations when I ask them to try it out, rather than me having to go into in-depth explanation or provide sample data.

Wondering the what the recommended practice is to create say a Python wrapper/client to make it even simpler to use for such service. I remember there being many wrappers for Dark Sky API and wondering if this was one of the things that made it easy-to-use/popular.
