+
+```python
+# Example: Version-aware vulnerability fetching
+async def get_vulnerabilities(self, **params):
+    # Automatically uses /vulnerability/agents for 4.8.0+
+    # Falls back to legacy endpoint for 4.7.x and below
+    return await self._request("GET", "/vulnerability/agents", params=params)
+```
+
