Use Web Search when you need the assistant to run a quick web query and return results.

​
Prerequisites

​
Requirements

  • Tool spec: { "name": "web_search", "type": "web_search_v1" }
  • No tool_context required

​
Basic request and response

This example validates a request that enables the web search tool: 
curl -X POST "https://{BASE_URL}/api/gpt/v1/messages/validate" \
  -H "Authorization: Bearer {API_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "default",
    "max_tokens": 64,
    "messages": [
      { "role": "user", "content": "Find recent updates about the EU AI Act." }
    ],
    "tools": [
      { "name": "web_search", "type": "web_search_v1" }
    ],
    "tool_choice": { "type": "auto" }
  }'
Example response: 
{ "valid": true, "errors": null }
To run the request, send the same body to POST /messages.
