Getting Price and Lot Size Numbers from Binance API

As a cryptocurrency developer, getting access to real-time market data is essential for building reliable trading systems. In this article, we will explore how to get price and lot size numbers from Binance API using their exchangeInfo endpoint.

Getting the ExchangeInfo response

The ExchangeInfo endpoint returns a JSON object with various exchange information, including the symbol, exchange name, base currency, quote currency, etc. Here is an example of what the response might look like:

{
"symbol": "LTCUDT",
"baseCurrency": "USD",
"quoteCurrency": "ETH",
"isPair": false,
"ExchangeInfo": {
"id": "1000000",
"name": "Binance",
"description": "",
"type": "exchange",
"currency": "USDT"
},
"apiVersion": 3
}

Price Digits

You can use the «symbol» and «basecurrency» response fields to extract the price digits. For example:

const symbol = 'LTCUDT';
const baseCurrency = 'USD';
const exchangeInfoResponse = {
// assuming this is the actual JSON object containing the API response
};
// assuming the price field is the current market price in USD
const price = exchangeInfoResponse.apiInfo.price;
console.log(Current price of ${symbol} ${baseCurrency}: ${price});

Lot size digits

To extract the lot size digits, you can use the `lots'' response field. For example:

const symbol = 'LTCUDT';
const baseCurrency = 'ETH';
const exchangeInfoResponse = {
// assuming this is the actual JSON object containing the API response
};
// assuming the lots field is the current lot size in ETH
const lots = exchangeInfoResponse.apiInfo.lots;
console.log(Current lot size of ${symbol} ${baseCurrency}: ${lots});

function getPriceDigits(symbol, basecurrency) {
const exchangeInfoResponse = {
apiInfo: {
symbol,
basecurrency
}
};
// Assuming the API response is a JSON object
const apiVersion = exchangeInfoResponse.apiInfo.version;
const endpoint =
get (endpoint)
.then(response => response.json())
.then(data => {
const price = data.apiInfo.price;
console.log(Current price of ${symbol} ${baseCurrency}: ${price});
})
.catch(error => console.error('Error:', error));
}
function getLotSizeDigits(symbol, basecurrency) {
const exchangeInfoResponse = {
apiInfo: {
symbol,
basecurrency
}
};
// Assuming the API response is a JSON object
const apiVersion = exchangeInfoResponse.apiInfo.version;
const endpoint = 
get (endpoint)
.then(response => response.json())
.then(data => {
const lots = data.apiInfo.lots;
console.log(Current lot size for ${symbol} ${baseCurrency}: ${lots});
})
.catch(error => console.error('Error:', error));
}
getPriceDigits('LTCUDT', 'USD');
getLotSizeDigits('LTCUDT', 'ETH');

To summarize, to get price and lot size digits from the Binance API using their exchangeInfo endpoint, you can use the response fieldssymbol'' and`basecurrency». You can then extract these values ​​using JavaScript functions or by directly parsing the JSON object.
