API reference for Gx402 SDK core functionality

Core Functions API

The core functions of the Gx402 SDK provide the essential x402 functionality for games, focusing on seamless payment processing and multi-chain integration.

initialize()

Initialize the Gx402 SDK with configuration options. This sets up the necessary infrastructure for x402 payment processing and multi-chain support.

JavaScript/WebGL

const Gx402 = new Gx402SDK({
  apiKey: 'your-api-key',
  environment: 'production', // or 'development'
  enableRealtimeSync: true,
  debug: false
});

await Gx402.init();

Configuration Options

• apiKey (string, required): Your Gx402 API key
• environment (string): ‘production’ or ‘development’ (default: ‘production’)
• enableRealtimeSync (boolean): Enable real-time synchronization (default: false)
• debug (boolean): Enable debug logging (default: false)

Unity (C#)

Gx402Manager.Initialize("your-api-key");

Gx402Manager.Configure(new Gx402Config {
    EnableRealtimeSync = true,
    LogLevel = Gx402LogLevel.Debug
});

Unreal Engine (C++)

FGx402Config Config;
Config.ApiKey = TEXT("your-api-key");
Config.bEnableRealtimeSync = true;
Config.LogLevel = EGx402LogLevel::Debug;

UGx402Manager::Initialize(Config);

processX402Data()

Process game data with x402 functionality. This function leverages the built-in x402 facilitator infrastructure to handle micropayments and other x402 protocol interactions.

JavaScript

const result = await Gx402.processX402Data({
  data: gameData,
  options: {
    feature: 'advanced-gaming',
    sync: true,
    encrypt: true
  }
});

Parameters

• params (Object): Processing parameters
  • data (any): Game data to process
  • options (Object, optional): Processing options
    • feature (string): Specific x402 feature to use
    • sync (boolean): Whether to sync the result
    • encrypt (boolean): Whether to encrypt the data

Returns

• Promise<any>: Processed data with x402 enhancements

Unity (C#)

var x402Result = Gx402Manager.ProcessX402Data(gameData);

Parameters

• object gameData: Game data to process with x402

Returns

• object: Processed data with x402 enhancements

Unreal Engine (C++)

FGx402Result Result = UGx402Manager::ProcessX402Data(GameData);

Multi-chain Support

The Gx402 SDK is designed with multi-chain support, accommodating both EVM (Ethereum Virtual Machine) and non-EVM blockchains. This ensures flexibility and broad compatibility for your game’s payment infrastructure.

Built-in x402 Facilitator Infrastructure

The SDK includes a built-in x402 facilitator infrastructure that handles the complexities of the x402 payment protocol. This allows developers to integrate micropayments without needing deep blockchain knowledge.
