Ethereum: Get ticker prices for all symbols via Websockets for Binance Futures
As the second largest market capitalization cryptocurrency, Ethereum (ETH) became increasingly popular among traders and investors. However, getting updated price information can be a challenge, especially when compared to Bitcoin (BTC). This is where webSockets-a technology comes in that allows real-time data exchange between servers over the internet.
In this article, we will explore how to use Binance Futures Websockets with API Websocket to receive current ticker prices for all Ethereum symbols. We will also analyze the requirements and documentation necessary to start.
Why Websockets?
Websockets offer several advantages over traditional APIs:
* Real -Time Updates : Websockets allows you to exchange quick and efficient data, allowing you to be ahead of changes in the market.
* LOW LATENCE : Using Websockets, you can reduce your latency to almost instant levels.
* Scalability
: With Websockets, you can handle a large number of simultaneous connections without sacrificing performance.
Introduction with Binance Futures Websocket API
To start with the Websocket API for Websocket for Ethereum, follow these steps:
- Create an account on [binance] ( one of the biggest cryptocurrency exchanges.
- Record a new API key on the binance panel and get a
carrier 'token that can be used to authenticate your requests.
- Install [node.js] ( Package managernpm
or yarn, which will allow you to create a new client Websocket for binance futures.
Using the WebSocket API to recover Ticker prices
After creating a WebSocket customer, you can use it to recover current ticker prices for all Ethereum symbols using the following code:
`JavaScript
Constant Axes = Requires (‘Axios’);
asynchronous function getticickerprices () {
constate URL = ‘
Headers const = {
‘x-api-chave’: process.env.binance_api_key,
‘x-api-secret’: process.env.binance_api_secret,
‘x-mdt-token’: process.env.mdt_token
};
to try {
CONST Response = awaits anxios.get (URL, {params: {}, headers});
CONST Data = Response.Data;
for (symbol const on data) {
if (object.prototype.hasownProperty.Call (data, symbol)) {
console.log ($ {symbol}: $ {date [symbol] .Price});
}
}
Return data;
} catch (error) {
console.error (error);
}
}
GetTickerPrices (). Then (() => console.log (‘Ticker prices successfully recovered!’)));
`
NOTE: Make sure to replace the reserved spaces (process.env.binance_api_key,process.env.binance_api_secret and process.mdt_token) with your Royal API credentials.
By following these steps, you can access current Ticker prices for all Ethereum symbols using the Binance Futures API. Always remember to follow the best practices for coding and authentication safe when working with APIs.
Conclusion
Websockets revolutionized the way we received real -time data from exchanges like Binance Futures. By using Websockets with Websocket’s API, you can stay up to date on market movements without depending on outdated or inaccurate prices.
