Quick Start

use zrxswap::{Client, Chain, QuoteRequest};

#[tokio::main]
async fn main() -> Result<(), zrxswap::Error> {
    // Create a client with your API key
    let client = Client::with_api_key("your-api-key")?;

    // Get an indicative price for swapping 1 ETH to USDC
    let request = QuoteRequest::sell(
        "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE", // Native ETH
        "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC
        "1000000000000000000", // 1 ETH in wei
    );

    let price = client.get_price(Chain::Ethereum, &request).await?;
    println!("You would receive: {} USDC", price.buy_amount);

    Ok(())
}
