I see on the API/service details page that gemini-2.5-flash-exp offers 10,000 free API calls per day. However, during actual calls, the following error appears:
{“error”: {“code”: 404, “message”: “models/gemini-2.5-flash-exp is not found for API version v1beta, or is not supported for generateContent. Call ListModels to see the list of available models and their supported methods.”, “status”: “NOT_FOUND”}}
