Looks for low-emission zones, congestion charge areas and access-restricted areas around a coordinate and reports each with its type, the vehicle classes it restricts where tagged, the operator, and the distance from your point. Zones are matched by the tags actually used for this in OpenStreetMap, including boundary relations and landuse areas carrying emission tags, and the response lists which tag produced each hit so a questionable match can be judged.
