Mapbox Terrain RGB image ' - mapbox

Question

I am new to mapbox and am trying to get the Terrain rgb data. I have followed the example from the documentation here :
https://www.mapbox.com/help/access-elevation-data/
and used the following query:
api.mapbox.com/v4/mapbox.terrain-rgb/{z}/{x}/{y}.pngraw?access_token={my_access_token}
which works find for zoom levels from 0 to 5 and returns RGB tiles of elevation data from a high level.
api.mapbox.com/v4/mapbox.terrain-rgb/5/0/0.pngraw?access_token={my_access_token}
I need to get the data at a much higher zoom level than 5, but once I use a zoom level above 5 it returns 'Tile Does Not Exist'.
The documentation says that there is data up to zoom of 15. My access token works and I have tried x,y tiles of 0, 0 (which should exist at all levels). Has anyone any help or suggestions ?

Answer 1

Had a similar issue and in my case the mistake was assuming that given an {x}/{y} tuple the zoom {z} was free to change, but it isn't, if zoom changes xy changes too.
To get the correct tiles I used mercantile (pip install mercantile)
import mercantile
print(mercantile.tile(-71.0638031, 42.3578952, 15))
>>> Tile(x=9915, y=12120, z=15)
