Want to have ECMWF animated map and data? Write Windy Plugin.
If you want to use ECMWF map and data in your app, then Windy API is wrong place to start. ECMWF data are proprietary and they MUST RUN on domain windy.com in the scope of Windy website.
Therefore ONLY way how to integrate your app is to develop Windy Plugin
And even inside Windy Plugin, all your transformation and work with ECMWF data must result in product that is available again on Windy.com.
