// Initialize the SDK with your API key
mut sdk := sdk_gemini.GeminiSDK{
    api_key: 'your-api-key-here'
}

// Send a simple prompt
response := sdk.send_prompt(
    structs.Models.gemini_2_0_flash,
    'Tell me about João Pessoa, Paraíba',
    'You are a tour guide from Brazil, specifically from the Northeast region, João Pessoa and Paraíba state'
