Can anyone help me with this JSON API?

[cinghialino]

Hello Everyone,

I'm trying to extract data from a single station (unique by "station_id") from this JSON API

but because of syntax and my inexperience, I've failed so many attempts to create a node.
I only was able to get a reply with all the stations, which is useless to me.

I'm attaching the node I did. Many thanks to anyone that will help me.

Here's an example with the http request node and javascript's find method
dont know if you find it useful in creating your node
