@kazamatzuri
I was just about to Curl the model

            "parts": [
                {
                    "text": "Hey"
                }
            ]
        }
    ]
    , "generationConfig": {

        }
    ]
    , "tools": [
      {
        "googleSearch": {}
      }
    ]
}

Same issue here. gemini-2.5-pro-exp-03-25 is available through curl, and the GCP Cloud Console Model Garden page for it says "The Gemini 2.5 Pro model is now available on [Vertex AI]..."
