+### Tool Search via Chat Completions Bridge
+
+You can also use tool search through the `/v1/chat/completions` endpoint by prefixing the model with `openai/responses/`. The request is routed through the Responses API but returns a standard chat completions response.
+
+
+
+
+```python showLineNumbers title="Tool Search via Chat Completions Bridge"
+import litellm
+
+response = litellm.completion(
+ model="openai/responses/gpt-5.4",
+ messages=[{"role": "user", "content": "Look up invoice INV-2024-001"}],
+ tools=[
+ {"type": "tool_search"},
+ {
+ "type": "namespace",
+ "name": "billing",
+ "description": "Billing and invoicing tools",
+ "tools": [
+ {
+ "type": "function",
+ "name": "get_invoice",
+ "description": "Get an invoice by ID",
+ "parameters": {
+ "type": "object",
+ "properties": {"invoice_id": {"type": "string"}},
+ "required": ["invoice_id"],
+ },
+ "defer_loading": True,
+ },
+ ],
+ },
+ ],
+)
+
+# Standard chat completions response
+for tool_call in response.choices[0].message.tool_calls:
+ print(f"Called: {tool_call.function.name}({tool_call.function.arguments})")
+```
