    """An api to ask LLM"""

    query {
        """the question to ask"""
        @string(min_len=3, max_len=100) // validate params with builtin directive @string
        question: str
    }

    // `ai` and `prompt` are keywords
    ai fn ask(question: str) -> str {
        let answer = prompt question;
        return answer;
    }
    // use query.name or query["name"] to access query parameter
    let answer = ask(query.question);
    return { answer };
}
