Consider adding elevation for points

[brewin]

stations and gridpoints both contain elevation values, but points does not. It could just be the grid point elevation since it already contains the other grid point data, or it could use a higher resolution source.

[dangelsaurus]

points returns a grid which represents a 2.5km grid area, elevation for the points endpoint would be misleading. you would probably be better off with something like https://www.opentopodata.org/
