Finding Coin Market Cap or Rank Using Binance API

When building a cryptocurrency application, it is important to have access to up-to-date market data. Binance API is one such platform that provides access to various financial data including market cap and rank for cryptocurrencies.

In this article, you will learn how to get the market cap or market cap rank of a coin using Binance C

API in a .NET application.

The Problem

As you have already noticed, Binance C

API does not provide a built-in feature to get the market cap or rank of a specific cryptocurrency. You have to manually query the API for this information.

Approach

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. We then loop through each coin and make an additional request using the “GetCoin” endpoint to get the market cap or rank data for that particular coin.

Example Code

Here’s some example code to get us started:

“sharp

Using System;

using System.Net.Http;

using System.Text.Json;

using Binance.Net;

public class MarketCapRequest

{

public String Symbol { get; aSet; }

}

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 = waiting GetMarketCapsAsyncFromResponse(request);

yield-marketcaps;

}

public async Task GetMarketCapsAsyncFromResponse(HttpResponseMessage response)

{

var listCoinsResponse = WaitingForResponse.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 = WaitingForGetMarketCapsAsyncFromCoinRequest(request);

if (marketCapResponse != null)

{

marketCaps.Add(marketCapResponse);

}

}

yield-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(await Response.Content.ReadAsStringAsync());

}

else

{

Console.WriteLine($”Could not 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 coin, making an additional request via the GetCoin endpoint to get the market cap or rank data. If successful, the response is added by 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 make an additional request using the GetMarketCapsAsyncFromCoinRequest method to get the market cap or rank data for that particular coin.

Conclusion

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

API in your .NET application. Remember to account for any errors that may occur during the request and handle them accordingly.
