Resolve a real estate listing (Immobilien-Inserat, Exposé) to the cadastral parcel (Flurstück) at the listing's coordinate and assess whether that match is plausible. Input is the listing's platform URL, e.g. an ImmobilienScout24, Immowelt or Kleinanzeigen link. The URL is only the lookup key — the tool never contacts the portal or a portal API. It calls the Assetfy API — GET https://assetfy.com/api/v1/real-estates/by-url for the listing (same lookup as assetfy_get_real_estate, so the listing must be in the Assetfy listing stock), then /api/v1/flurstueck and the /api/v1/flurstueck/{gml_id} endpoints for the parcel. The tool reads the listing coordinate, looks up the Flurstück there in the ALKIS cadastre and adds its parcel profile: area, GFZ/GRZ potential, Bodenrichtwert, buildings and actual land use. match_assessment returns status plausible_match, needs_review, unlikely_match or no_match with a confidence, from comparing the listed plot area with the parcel area and a house listing with the buildings on the parcel. Portal coordinates are often only approximate — when the status is not plausible_match, use assetfy_match_listing_to_parcel, which searches by ZIP and plot area instead. A listing without a street has no property coordinate (the map places it on a random point in its postcode area); the tool then reads no parcel and names assetfy_match_listing_to_parcel as next_step.
