Hi, I work for the US Forest Service and develop a mobile application called the Fire Weather Alert System (open source and distributed free of charge). We'd like to use your free tier webcams API to display cameras in our app. I wanted to check that this was a valid use of the free tier. We would use a single API key to display cameras based on the user's zoom in the mapping interface of our app. When the user clicks on a camera we will include a link to windy.com/webcams to ensure your API is credited in our app. Is this a valid use of the free tier?
