    pub news: NewsService,
    pub common: CommonService,
    pub market: MarketService,

async fn main() -> dceapi::Result<()> {
    let config = Config::new()
        .with_api_key("your-api-key")
        .with_secret("your-secret");
     
    let client = Client::new(config)?;
     
    // Get current trade date
    let trade_date = client.common.get_curr_trade_date(None).await?;
    println!("Trade date: {}", trade_date.date);

    .with_secret("your-secret");

let client = Client::new(config).expect("Failed to create client");

pub fn from_env() -> Result<Self>
