RE: Programming Tutorial: Renting your splinterlands card collection with python

First of all, I would like to appreciate all your time, attention and detail put on this thread. I have been delaying learning python and you just gave me a great will to finally start.

However, I have been getting erros at the function get_rental_listing. It doesn't matter what I do, it always returns "None". I've tried my own cards that were renting already, but also cards there were not renting and I always get the same result.

I believe the error is not on the function itself, but the api key:

"https://api2.splinterlands.com//market/for_rent_by_card"

Is this api key correct? I tried looking up at kiokizz github api documentation, but there isn't any related to rent, only sale. (https://github.com/kiokizz/Splinterlands-API)

Once again, thank you very much for what you are doing for the community. As a busy man who can't be looking at my rentals all day long, this is awesome.
