Ethereum: Get Ticker Prices for All Symbols via Websockets for Binance Futures

As the second-largest cryptocurrency by market capitalization, Ethereum (ETH) has become increasingly popular among traders and investors. However, getting up-to-date price information can be a challenge, especially when compared to Bitcoin (BTC). That’s where websockets come in – a technology that enables real-time data exchange between servers over the internet.

In this article, we will explore how to use websockets with Binance Futures’ websocket API to get current ticker prices for all Ethereum symbols. We’ll also review the requirements and documentation needed to get started.

Why Websockets?

Websockets offer several advantages over traditional APIs:

Real-time updates: Websockets enable fast and efficient data exchange, allowing you to stay ahead of market changes.

Low latency: By using websockets, you can reduce your latency to near-instantaneous levels.

Scalability: With websockets, you can handle a large number of concurrent connections without sacrificing performance.

Getting Started with Binance Futures Websocket API

To get started using the Binance Futures WebSocket API for Ethereum, follow these steps:

Create an account on [Binance]( one of the largest cryptocurrency exchanges.

Register a new API key on your Binance dashboard and obtain a Bearer token that can be used to authenticate your requests.

Install the [Node.js]( package manager npm or yarn, which will allow you to create a new WebSocket client for Binance Futures.

Using Websocket API to Retrieve Ticker Prices

Once you have created a WebSocket client, you can use it to retrieve the current ticker prices for all Ethereum symbols using the following code:


const axis = require('axis');


async function getTickerPrices ( ) { ) ;

  const url = '

  const headers = { const headers = {

    'x-api-key': process.env.BINANCE_API_KEY,

    'x-api-secret': process.env.BINANCE_API_SECRET,

    'x-mdt-token': process.env.MDT_TOKEN

  };


  try {

    const response = await axios . get ( url , { params : { } , headers });

    const data = response.data;


    for ( const symbol in data ) {

      if ( Object . prototype . hasOwnProperty . call ( data , symbol )) { ;

        console.log(${symbol}: ${data[symbol].price});

      } }

    } }


    return data ;

  } catch (error) {

    console.error(error);

  } }

} }


getTickerPrices().then(() => console.log('Ticker prices retrieved successfully!'));

Note: Be sure to replace the placeholders (process.env.BINANCE_API_KEY, process.env.BINANCE_API_SECRET, and process.env.MDT_TOKEN) with your actual API credentials.

You should be able to access current ticker prices for all Ethereum symbols using Binance Futures’ websocket API. Remember to always follow best practices for secure coding and authentication when working with APIs.

Conclusion

Websockets have revolutionized the way we receive real-time data from exchanges like Binance Futures. By using websockets with their websocket API, you can stay up-to-date on market movements without relying on outdated or inaccurate ticker prices.
