OSM API returns different values with and without debug mode

Question

If you use the Nominatim API from Open Street Map, once in debug mode and once without debug mode you get different data.

Example URLs:

https://nominatim.openstreetmap.org/reverse.php?lat=51.06810&lon=8.79765&zoom=18&format=jsonv2&debug=1

https://nominatim.openstreetmap.org/reverse.php?lat=51.06810&lon=8.79765&zoom=18&format=jsonv2

Important for me is especially the 'website' field, which is present in debug mode, but not otherwise.

How can I get all the data?

Answer 1

Use extratags to get this data:
