Hello I'm trying to use the precipitation weather map layer but it doesn't work.

where xxx is my api key.
Is the url correct ?
No, the url is not correct.
You should use coordinates from Mercator projection https://en.wikipedia.org/wiki/Mercator_projection
For example https://tile.openweathermap.org/map/precipitation_new/4/1/1.png?appid=xxx
