Does my novice approach to interface with Weather Underground make sense?

I use node red, with a MQTT node to subscribe to the TTN API, then parse the JSON file and build the URL with a function node and HTTP request to finally send to WU

Seems to work but they dont publish the URL structure/API anywhere that I can find it easily anymore
