to get a market top bound or coin rank using binance api

When developing a cryptocurrency program, it is necessary to have access to the latest market data. Binance API is one of these platforms providing access to various financial data, including market capitalization and cryptocurrency rank.

In this article, we will investigate how to get the top of the coin market or the top boundary of the market using Binance C

API .NET.

Question

As you have already learned, the Binance C

API does not provide built -in features to obtain the top limit of the market or the rank of specific cryptocurrency. You must manually ask the API of this information.

Attitude

To achieve this, we will use the “rear point of the list coins that allows you to scan all the list of Binance exchange coins. Then we will start through each coin and provide an additional query using the final point of Getcoin to get the top limit of the market or to divide that particular coin.

CODE EXAMPLE

Here are some examples of code so we can start:

`Cssharp

using the system;

using system.net.http;

Use of System.text.json;

using binance.net;

Public -class Marketcaprequest

{

Public line symbol {get; set; }

}

Public Async Task Getmarketcapsayync ()

{

VAR request = new httpclient (). Posturc (

New StringContent (JSONSERALIALIERIERIALIE (New Listcoinsrequest ()), Encoding.utf8, Application/JSON);

wait for the request.content.Readfromstaskasyanc ();

VAR MARKETCAPS = waiting for Getmarketcapsancfromresponse (request);

return MarketCaps;

}

Public Async Task “Getmarketcapesyncfromrespossse” (HttPresponsemeMessage Response)

{

VAR LISTOSRESPONSE = Wait for the answer.content.readstringing ();

VAR Listcoins = Jsonserialize.Deserialsis (Listcoinsresponse);

VAR MARKETCAPS = New List ();

Foreach (Var coin Listcoins)

{

VAR REQUEST = NEW MARKETCAPREQUEST {symbol = coin.symbol};

VAR MARKETCAPRESPONSE = waiting for getmarketcapesyncfromcoinrequest (request);

IF (MarketCapresponse! = Null)

{

MarketCaps.add (MarketCapresponse);

}

}

return MarketCaps;

}

Society’s Async Task Getmarketcapesyncfromcoinrequest (MarketCaprequest request)

{

VAR URL = ” + request.symbol;

VAR REQUESTURL = $ ” {reQuest.symbol imlimit = 100″;

using VAR httpclient = new httpclient ();

VAR Answer = Wait for httpclient.getyank (Requesturl);

If (resage.issuccessStatuscode)

{

return Jsonserializializeris.Deserialize (wait for the answer.content.readstringing ());

}

elsewhere

{

Console.writeline ($ “” Failed to scan {reQuest.symbol} market cover: {Response.statuscode} “);

return null;

}

}

`

How does it work

The Getmarketcapesync method creates a new list of coins and loops through each coin, with an additional query, using the final point for Getcoin to get the top limit of the market or rating data. If you are lucky, it adds a response from Getmarketcapesyncfromcoinrequest method.

Remember that we use the alternating Listcoinsresponse to get all the list of Binance Exchange coins. Then we go through each coin and provide an additional query using the Getmarketcapsasyncfromcoinrequest method to get the top limit of the market or divide that particular coin.

Conclusion

Based on this example, you should be able to crawl the coin market top or the top limit of the market using Binance C

API. Remember to handle all the mistakes that can occur during the request and process them accordingly.
