@scherervictor Would you be interested in contributing this functionality to the Semantic Kernel?

[scherervictor]

@markwallace-microsoft sure! I could try to do that.

@markwallace-microsoft If the docs is:

curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash:generateContent?key=$GOOGLE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
      "contents": [
          {
              "parts": [
                  {"text": "What is the current Google stock price?"}
              ]
          }
      ],
      "tools": [
          {
              "google_search": {}
          }
      ]
  }' > result.json

cat result.json

Would it be equivelent to this in SK?

GeminiPromptExecutionSettings settings = new()
{
    ModelId = AIModel.Google_Gemini25ProPreview.ToModelIdentifier(),
    ServiceId = AIModel.Google_Gemini25ProPreview.ToModelIdentifier(),
    MaxTokens = 32768,
    ExtensionData = new Dictionary<string, object>()
    {
        ["tools"] = new List<Dictionary<string, object>>
        {
            new() 
            {
                ["google_search"] = new Dictionary<string, object>()
            }
        }
    }
};
