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

As the second-largest cryptocurrency by market cap, 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 allows real-time data exchange between servers over the internet.

In this article, we’ll learn how to use websockets with the Binance Futures websocket API to receive current ticker prices for all Ethereum symbols. We’ll also go over 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 simultaneous connections without sacrificing performance.

Getting started with Binance Futures Websocket API

To get started with 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]( npm or yarn package manager, which will allow you to create a new WebSocket client for Binance Futures.

Using the 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 tokens using the following code:

const axes = require('axes');
async function getTickerPrices() {
const url = '
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 = wait axios.get(url, { parameters: {}, headers });
const date = response.date;
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 successfully retrieved!'));

Note: Make 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.

By following these steps, you should be able to access current ticker prices for all Ethereum tokens using the Binance Futures Websocket API. Always remember to follow secure coding and authentication best practices 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 on top of market movements without relying on outdated or inaccurate ticker prices.
