blender 4.1
blender gis 2.2.10

learn and tried from blender > scripting
>>> bpy.ops.view3d.map_search(query = 'rome italy')

result not expected
{'FINISHED'}

expected result
should return latitude and longitude
or
x and y value

>>> bpy.ops.view3d.map_start(src='GOOGLE', grd='WM', lay='SAT', dialog="MAP", query="", zoom=0, recenter=False)

expected result
can use python api scripting
e.g.

f = open("stl_converter.py", "w")
f.write("""
import bpy

bpy.ops.wm.read_factory_settings(use_empty = True)

bpy.ops.view3d.map_start(src='GOOGLE', grd='WM', lay='SAT', dialog="MAP", query="", zoom=0, recenter=False)

# get elevation opentopography or marine-geo.org, don't know the python api syntax for this perhaps use : bpy.ops.object.shade_smooth()

bpy.ops.export_mesh.stl(filepath = '/content/stl_converter.stl', ascii = False)

bpy.ops.wm.save_as_mainfile(filepath = "/content/stl_converter.blend")
""")
f.close()

!blender --background --python terrain.generator.py

question
how can achieve it using blend gis for python api scripting ?

best regards

Blender operator can only be executed in a specific context : https://docs.blender.org/api/current/bpy.ops.html
In this case, the 3d view, not the Python console, that why tit raise an error. Also an operator only return a value of his state of execution.

Internally this operator just use the Nomatim API
