There was a problem hiding this comment.
here we coud directly do
num_bands = image.count

What I am changing
I'm adding a basic GetFeatureInfo implementation to the Titiler WMS extension. This provides compatibility so that various WMS clients can automatically provide a users with queried point values.
How I did it
GetFeatureInfo reuses most of the logic from GetMap and queries a point within the returned image tile.
How you can test it
You can test this using the cog/wms endpoint in a WMS client like QGIS or nationalmap.gov.au and using the feature info capabilities to query a point. For some reason in QGIS some datasets like https://oin-hotosm.s3.amazonaws.com/56f9b5a963ebf4bc00074e70/0/56f9c2d42b67227a79b4faec.tif require invert axis orientation to be selected.
