api.geoprimitives.dev geometry union

https://api.geoprimitives.dev/v1/geometry/union

needs params

Dissolve overlapping or adjacent polygons into a single shape: merging parcels, coverage areas or service zones into one boundary before measuring or testing it. Send a FeatureCollection of Polygons or MultiPolygons; the answer is a single Polygon or MultiPolygon Feature, or null with empty:true when nothing is left. Clipping is planar in longitude/latitude, the way every polygon-clipping library

Bazaar lists this endpoint, but when we called it we got HTTP 400 instead of a payment challenge.
