Binance Public API Connector Rust

This is a lightweight library that works as a connector to Binance public API

  • Supported APIs:
    • /api/*
    • /sapi/*
    • Spot Websocket Market Stream
    • Spot User Data Stream
  • Test cases and examples
  • Customizable base URL and request timeout
  • Blocking and Non-blocking clients
  • Response Metadata
  • Supports HMAC and ED25519 authentications but not RSA authentication.

RESTful APIs

The Binance Rust Connector exposes two abstraction layers to integrete with Binance RESTful APIs; a high level abstraction consisting of maintained functions mapped one-to-one with Binance API endpoints, and a low level generic abstraction for more control over the request.

High Level Usage Example

use env_logger::Builder;
use binance_spot_connector_rust::{
    http::Credentials,
    hyper::{BinanceHttpClient, Error},
    market::{self, klines::KlineInterval},
    trade
};

#[tokio::main]
async fn main() -> Result<(), Error> {
    Builder::from_default_env()
        .filter(None, log::LevelFilter::Info)
        .init();

    let credentials = Credentials::from_hmac("api-key".to_owned(), "api-secret".to_owned());
    let client = BinanceHttpClient::default().credentials(credentials);

    // Get candlesticks for BTCUSDT with a 1 minute interval
    let data = client.send(market::klines("BTCUSDT", KlineInterval::Minutes1)).await
        .expect("Request failed")
        .into_body_str().await
        .expect("Failed to read response body");
    log::info!("{}", data);

    // Get the last 10 candlesticks for BTCUSDT with a 1 hour interval
    let data = client.send(market::klines("BTCUSDT", KlineInterval::Hours1).limit(10)).await
        .expect("Request failed")
        .into_body_str().await
        .expect("Failed to read response body");
    log::info!("{}", data);

    // Get account information
    let data = client.send(trade::account()).await
        .expect("Request failed")
        .into_body_str().await
        .expect("Failed to read response body");
    log::info!("{}", data);

    Ok(())
}

Examples for other endpoints are available in the examples folder.

Low Level Usage Example

use binance_spot_connector_rust::{
    http::{request::RequestBuilder, Method},
    hyper::{BinanceHttpClient, Error},
};
use env_logger::Builder;

#[tokio::main]
async fn main() -> Result<(), Error> {
    Builder::from_default_env()
        .filter(None, log::LevelFilter::Info)
        .init();

    let client = BinanceHttpClient::default();

    let builder = RequestBuilder::new(Method::Get, "/api/v3/klines")
        .params(vec![("symbol", "BTCUSDT"), ("interval", "1m")]);

    // Get candlesticks for BTCUSDT with a 1 minute interval
    let data = client
        .send(builder)
        .await
        .expect("Request failed")
        .into_body_str()
        .await
        .expect("Failed to read response body");
    log::info!("{}", data);

    Ok(())
}

Websocket

use binance_spot_connector_rust::{
    market::klines::KlineInterval, market_stream::kline::KlineStream,
    tokio_tungstenite::BinanceWebSocketClient,
};
use env_logger::Builder;
use futures_util::StreamExt;

#[tokio::main]
async fn main() {
    Builder::from_default_env()
        .filter(None, log::LevelFilter::Info)
        .init();
    // Establish connection
    let (mut conn, _) = BinanceWebSocketClient::connect_async_default()
        .await
        .expect("Failed to connect");
    // Subscribe to streams
    conn.subscribe(vec![
        &KlineStream::new("BTCUSDT", KlineInterval::Minutes1).into()
    ])
    .await;
    // Read messages
    while let Some(message) = conn.as_mut().next().await {
        match message {
            Ok(message) => {
                let binary_data = message.into_data();
                let data = std::str::from_utf8(&binary_data).expect("Failed to parse message");
                log::info!("{:?}", data);
            }
            Err(_) => break,
        }
    }
    // Disconnect
    conn.close().await.expect("Failed to disconnect");
}

Examples for other websocket streams are available in the examples folder.

Heartbeat

Once connected, the websocket server sends a ping frame every 3 minutes and requires a response pong frame back within a 10 minutes period. This package handles the pong responses automatically.

Testnet

/api/* endpoints can be tested in Spot Testnet. /sapi/* endpoints are not supported.

let client = BinanceHttpClient::with_url("https://testnet.binance.vision");

Base URL

It's recommended to pass in the baseUrl parameter, even in production as Binance provides alternative URLs in case of performance issues:

  • https://api1.binance.com
  • https://api2.binance.com
  • https://api3.binance.com

Timeout

The default timeout is 100,000 milliseconds (100 seconds).

Logging

This library implements the standard rust logging framework which works with a variety of built-in and third-party logging providers.

Usage Example

use binance_spot_connector_rust::{
    http::Credentials,
    hyper::{BinanceHttpClient, Error},
    wallet,
};
use env_logger::Builder;

#[tokio::main]
async fn main() -> Result<(), Error> {
    Builder::from_default_env()
        .filter(None, log::LevelFilter::Debug)
        .init();

    let credentials = Credentials::from_hmac("api-key".to_owned(), "api-secret".to_owned());
    let client = BinanceHttpClient::default().credentials(credentials);

    // Get candlesticks for BTCUSDT with a 1 minute interval
    let data = client
        .send(wallet::system_status())
        .await
        .expect("Request failed")
        .into_body_str()
        .await
        .expect("Failed to read response body");

    Ok(())
}
