MEXC API for Delphi & CBuilder

What's new

The release introduces two new classes:

• TsgcWSAPI_MEXC – implements the Spot WebSocket and REST API.
• TsgcWSAPI_MEXC_Futures – implements the Futures WebSocket and REST API.

Together, these components allow you to:

• Connect to public market data (tickers, trades, depth, etc.).
• Manage private data streams (orders, balances, positions).
• Execute REST calls for placing or canceling orders, checking balances, and retrieving account history.
• Handle real-time trading events through easy-to-use Delphi events.

All of this is implemented natively, no external dependencies, just pure Delphi / C++Builder performance. 

Simple Integration for Delphi and CBuilder

Using the MEXC API in sgcWebSockets is intuitive and consistent with other sgcWebSockets APIs like Binance, Bybit, or KuCoin. 

Example: Connecting to the MEXC Spot WebSocket

var
  WSClient: TsgcWebSocketClient;
  MEXC: TsgcWSAPI_MEXC;
begin
  WSClient := TsgcWebSocketClient.Create(nil);
  MEXC := TsgcWSAPI_MEXC.Create(nil);
  MEXC.Client := WSClient;
  MEXC.MEXCAPI.ApiKey := 'YOUR_KEY';
  MEXC.MEXCAPI.ApiSecret := 'YOUR_SECRET';
  MEXC.MEXCUserDataStreams.UserStream := True;
  if WSClient.Connect then
    MEXC.SubscribeTrade('BTCUSDT');
end; 

This snippet connects your Delphi application to the MEXC Spot exchange and subscribes to live trade updates for BTC/USDT.
The component handles message parsing, authentication, and reconnection automatically.

Example: Fetching Data via HTTP REST (Spot API) 

var
  MEXC: TsgcWSAPI_MEXC;
  Response: string;
begin
  MEXC := TsgcWSAPI_MEXC.Create(nil);
  MEXC.MEXCAPI.ApiKey := 'YOUR_KEY';
  MEXC.MEXCAPI.ApiSecret := 'YOUR_SECRET';
  // Retrieve account information
  Response := MEXC.REST_API.GetAccountInfo;
  Memo1.Lines.Text := Response;
end; 

Real-Time Futures Trading with Delphi and CBuilder

 The MEXC component also supports the Futures API, allowing developers to manage perpetual contracts and real-time positions. 

Example: Subscribing to Futures Market Data

var
  WSClient: TsgcWebSocketClient;
  MEXC: TsgcWSAPI_MEXC_Futures;
begin
  WSClient := TsgcWebSocketClient.Create(nil);
  MEXC := TsgcWSAPI_MEXC.Create(nil);
  MEXC.Client := WSClient;
  MEXC.MEXCAPI.ApiKey := 'YOUR_KEY';
  MEXC.MEXCAPI.ApiSecret := 'YOUR_SECRET';
  if WSClient.Connect then
    MEXC.SubscribeTrade('BTCUSDT');
end; 

Unified Architecture and Documentation

The new component follows the same design philosophy that makes sgcWebSockets the most developer-friendly communication library for Delphi and CBuilder:

• Consistent class hierarchy across all exchanges (Binance, KuCoin, Bybit, and now MEXC).
• Unified event model for WebSocket messages.
• Simplified authentication and automatic request signing.
• Full SSL/TLS support and integrated logging.

Whether you're creating trading dashboards, portfolio managers, or high-frequency bots, sgcWebSockets 2025.10.0 empowers you to focus on your logic, not on API plumbing. 

Conclusion

With the release of sgcWebSockets 2025.10.0, Delphi and CBuilder developers can now integrate MEXC Spot and Futures APIs directly into their applications with minimal effort.
Real-time data, RESTful endpoints, authentication, and market access — all in one place, all natively coded in Delphi.
