+
+**Purpose:** Type-safe, validated data models for all API responses and business logic
+
+**9 Comprehensive Models:**
+- `CoordinatePoint` - ITM coordinates (frozen/immutable)
+- `Address` - Israeli address with optional coordinates
+- `AutocompleteResult` & `AutocompleteResponse` - Search results
+- `Deal` - Real estate transaction with computed `price_per_sqm` field

+client = GovmapClient()
+
+# Returns AutocompleteResponse model
+result = client.autocomplete_address("חולון")
+coords = result.results[0].coordinates  # Optional[CoordinatePoint]
+
+# Returns List[Deal]
+deals = client.get_street_deals("polygon123")
+for deal in deals:
+    price = deal.deal_amount  # float (snake_case)
+    price_per_sqm = deal.price_per_sqm  # Computed field!
+
+# Serialize to dict/JSON when needed
+deal_dict = deal.model_dump()
+deal_json = deal.model_dump_json()
