Getting Market Cap or Coin Ranking Using Binance API

When building a cryptocurrency application, access to up-to-date market data is essential. One such platform is Binance API, which provides access to various financial data, including cryptocurrency market cap and ranking.

In this article, we will show you how to get the market cap or market cap ranking of a given coin using Binance C

API in a .NET application.

Problem

As you may have noticed, Binance C

API does not provide a built-in functionality to get the market cap or ranking of a specific cryptocurrency. To get this information, you need to manually query the API.

Get Close

To achieve this, we will use the “List Coins” endpoint, which allows you to get a list of all the coins on the Binance exchange. Then we’ll loop through each coin and make an additional request using the GetCoin endpoint to retrieve market cap or ranking data for a specific coin.

Sample Code

Here’s some sample code to get us started:

using System;
using System.Net.Http;
using System.Text.Json;
using Binance.Net;
public class MarketCapRequest
{
public string Symbol { get; set; }
}
public async task GetMarketCapsAsync()
{
var request = new HttpClient().PostAsync(" 
new StringContent(JsonSerializer.Serialize(new ListCoinsRequest()), Encoding.UTF8, "application/json"));
await request.Content.ReadFromTaskAsync();
var marketCaps = await GetMarketCapsAsyncFromResponse(request);
return marketCaps;
}


public async Task GetMarketCapsAsyncFromResponse(HttpResponseMessage response)

{

    var listCoinsResponse = wait for response.Content.ReadAsStringAsync();

    var listCoins = JsonSerializer.Deserialize(listCoinsResponse);


    var marketCaps = new List();


    foreach (var coin in listCoins)

    {

        var request = new MarketCapRequest { Symbol = coin.Symbol };

        var marketCapResponse = wait for GetMarketCapsAsyncFromCoinRequest(request);

        if (marketCapResponse != null)
{
marketCaps.Add(marketCapresponse);
}
}
return marketCaps;
}
public async task GetMarketCapsAsyncFromCoinRequest(MarketCapRequest request)
{
var url = " + request.Symbol;
var requestUrl = $"
using var httpClient = new HttpClient();
var response = await httpClient.GetAsync(requestUrl);
if (response.IsSuccessStatusCode)
{
return JsonSerializer.Deserialize(expect response.Content.ReadAsStringAsync());
}
else
{
Console.WriteLine($"Failed to get market cap for {request.Symbol}: {response.StatusCode}");
return null;
}
}

How ​​it works

The GetMarketCapsAsync method creates a new list of coins and loops through each one, sending an additional request using the GetCoin endpoint to retrieve market cap or ranking data. If successful, it adds the response from the GetMarketCapsAsyncFromCoinRequest method.

Note that we use the ListCoinsResponse variable to get a list of all the coins on the Binance exchange. We then loop through each coin and send an additional request using the GetMarketCapsAsyncFromCoinRequest method to get the market cap or ranking data for a specific coin.

Conclusion

By following this example, you should be able to get the market cap or market cap ranking of a coin using the Binance C

API in your .NET application. Be sure to handle any errors that may occur during the request and process them appropriately.
