Get nearest points

This endpoint retrieves all points sorted from nearest to farthest from an origin point.
In scenarios where identical geographic names exist (e.g., multiple places named 'Holm'), the geo_code is prioritized over the geo_name to ensure accuracy. f ambiguity persists, the API returns an error message containing possible codes for the name.
Please note that for postcodes, geo_code and geo_name are identical (as they are numeric)
