GPT-5.4

cURL
curl https://crazyrouter.com/v1/responses \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "gpt-5.4",
    "input": "Use web search to find one current headline from a major technology news site published recently.",
    "tools": [
      {
        "type": "web_search_preview"
      }
    ]
  }'
生产验证返回的关键 output.type： 
["web_search_call", "web_search_call", "message"]

Claude Sonnet 4.6

cURL
curl https://crazyrouter.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "claude-sonnet-4-6",
    "messages": [
      {
        "role": "user",
        "content": "Find one recent technology headline. Use web search and do not answer from memory."
      }
    ],
    "web_search_options": {
      "search_context_size": "medium",
      "user_location": {
        "approximate": {
          "timezone": "Asia/Shanghai",
          "country": "CN"
        }
      }
    },
    "max_tokens": 200
  }'
生产验证返回的关键字段： 
{
  "tool_calls": [
    {
      "type": "function",
      "function": {
        "name": "remote_web_search"
      }
    }
  ],
  "finish_reason": "tool_calls"
}
这说明在 Crazyrouter 的 OpenAI-compatible 路由下，Claude 4.6 的联网搜索会以工具调用形式暴露出来。 首轮联调建议：
  • 提示词里明确写出 Use web search
  • 同时补一句 do not answer from memory
  • 如果提示词过弱，模型可能直接给出文本回答，不一定显式触发 remote_web_search

Gemini 3 Pro Preview

cURL
curl "https://crazyrouter.com/v1beta/models/gemini-3-pro-preview:generateContent?key=YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      {
        "role": "user",
        "parts": [
          {
            "text": "Use Google Search to find one recent headline from a major technology news site."
          }
        ]
      }
    ],
    "tools": [
      {
        "googleSearch": {}
      }
    ]
  }'
生产验证返回了以下关键字段：
  • groundingMetadata.webSearchQueries
  • groundingMetadata.groundingChunks
  • groundingMetadata.groundingSupports
