Geocode with Nominatim

Convert an address or place name to geographic coordinates and a bounding box using the OpenStreetMap Nominatim API.

Inputs:

• Address / Place Name. Address or place name to geocode, e.g. Basel, Switzerland or Marienplatz 1, München;

• Buffer (km). Expand the bounding box by this distance in km (default: 0). Useful to create a working area around a point address.

Outputs:

• JSON string with west, south, east, north — directly usable as bbox input for other tools;

• Human-readable geocoding result summary;

• Full JSON manifest with coordinates, bbox, area, and metadata.
