-
-search = ConstructSearch(city_code=Seoul.JONGNRO)
-search.set_result_count(1)
-print(search.get_url())
+from kheritageapi.api import Search, ItemDetail, EventSearch
+from kheritageapi.models import CityCode, Seoul, HeritageType
+
+# Search for 15 historic sites in Seoul's Jongno district
+search = Search(result_count=15, city_code=CityCode.SEOUL, district_code=Seoul.JONGNRO, canceled=False,
+                heritage_type=HeritageType.HISTORIC_SITE)
+result = search.commit_search()
+
+# Get detailed information on the first item
+detail = ItemDetail(result.items[0])
+detail_info = detail.info()
+print(detail_info)
+
+# Also, you can get images and videos of the item
+images = detail.image()
+print(images)
