0G Kit - Simplified SDK for easy integration!

A developer-friendly SDK that makes it easy to interact with the 0G decentralized AI network. Go from multiple lines of complex setup to just 2 lines of code and get any 0G infrastructure integrated into your app!

What Complexity Does 0G Kit Handle For You?

The 0G Kit abstracts away the following complex technical details:

🧠 0G Compute Network

• Broker Initialization - No need to manually create and configure the 0G Compute Network broker with ethers.js providers, wallets etc

• Provider Discovery - Automatic service discovery and provider selection instead of manually calling broker.inference.listService()

• Provider Acknowledgment - Automatic on-chain provider acknowledgment via broker.inference.acknowledgeProviderSigner()

• Service Metadata Retrieval - No need to manually fetch endpoint and model information with broker.inference.getServiceMetadata()

• Request Header Generation - Automatic generation of single-use authenticated headers via broker.inference.getRequestHeaders()

• HTTP Request Management - Handles all the fetch API calls, error handling, and response parsing

• Response Verification - Automatic response processing and verification for TEE-enabled services

• Fee Settlement - Automatic micropayment handling and fee settlement

• Account Management - Simplified balance checking, deposits, and withdrawals without direct ledger interactions

• Error Handling - Comprehensive error handling for network issues, insufficient funds, and provider failures

• Retry Logic - Built-in retry mechanisms for failed requests

• Timeout Management - Automatic request timeout handling and cleanup

💾 0G Storage Network

• Indexer Initialization - No need to manually create and configure the 0G Storage indexer with ethers.js providers, wallets etc

• File Processing - Automatic file handling, Merkle tree generation, and buffer management

• Upload Management - Handles all upload operations, transaction signing, and blockchain interactions

• Download Management - Automatic file retrieval and verification using root hashes

• Gas Management - Automatic gas price optimization (5x default) and transaction fee handling

• Error Handling - Comprehensive error handling for network issues, file operations, and blockchain failures

• Retry Logic - Built-in retry mechanisms for failed uploads/downloads

• Timeout Management - Automatic operation timeout handling and cleanup

Installation

• Install 0G kit npm install 0g-kit
• Get some 0G faucet from Link
• Add your EVM private key to .env ( PRIVATE_KEY )

⚠️ Important: For first time usage, it automatically deposits 0.05 OG to activate your broker account. Subsequent calls won't auto-deposit unless you explicitly call the deposit function!

Import Options

// Compute-only imports  
import { chat, useDeepseek, useLlama, useQwen } from '0g-kit';

// Storage-only imports
import { uploadFile, downloadFile, uploadFileWithGas, uploadKeyValueFile, downloadKeyValueFile, uploadStream, downloadStream } from '0g-kit/storage';

🧠 0G Compute Network

Basic Usage (2 lines!)

// AI Chat
import { chat } from '0g-kit';
const response = await chat('Hello, how are you?');

Model-Specific Functions

// Use DeepSeek model specifically
import { useDeepseek } from '0g-kit';
const response = await useDeepseek('Hello, how are you?')

// Use Llama model specifically
import { useLlama } from '0g-kit';
const response = await useLlama('Hello, how are you?')

// Use Qwen model specifically
import { useQwen } from '0g-kit';
const response = await useQwen('Hello, how are you?')

Service Discovery

// Get list of available models and providers
import { getAvailableModels } from '0g-kit';
await getAvailableModels().then(console.log());

// Get detailed service information
import { listServices } from '0g-kit';
await listServices().then(console.log());

Manage Your Balance

// Check balance
import { getBalance } from '0g-kit';
await getBalance().then(console.log());

// Deposit 0.5 0G from wallet to broker account
import { deposit } from '0g-kit';
await deposit(0.5); 

// Withdraw 0.2 0G from your broker account to wallet
import { withdraw } from '0g-kit';
await withdraw(0.2); 

Advanced Configuration

import { initZeroG } from '0g-kit';

// Advanced setup with custom options
initZeroG({
  privateKey: '0x1234567890abcdef...',
  rpcUrl: 'https://evmrpc-testnet.0g.ai',
  autoDeposit: true,
  defaultModel: 'deepseek-chat', 
  timeout: 30000,
  retries: 3,
  logLevel: 'info' 
});

Chat Options

will be implemented once 0G activates the feature on each models ⚠️

�� 0G Storage Network

File Storage Operations

// Upload a file (2 lines!)
import { uploadFile } from '0g-kit';
const result = await uploadFile('./my-file.txt');
console.log('Root Hash:', result.rootHash);

// Download a file (2 lines!)
import { downloadFile } from '0g-kit';
await downloadFile(result.rootHash, './downloaded-file.txt');

// Upload with custom gas price
import { uploadFileWithGas } from '0g-kit';
const result = await uploadFileWithGas('./my-file.txt', '10000000'); // 10 gwei
console.log('Root Hash:', result.rootHash);

// Upload with custom options
import { uploadFile } from '0g-kit';

⚙️ Configuration Options

🔧 Error Handling

The SDK provides clear error types:

import { ConfigurationError, NetworkError, InsufficientFundsError } from '0g-kit';

try {
  const response = await chat('Hello');
} catch (error) {
  if (error instanceof ConfigurationError) {
    console.log('Configuration issue:', error.message);
  } else if (error instanceof InsufficientFundsError) {
    console.log('Need more funds:', error.message);
  } else if (error instanceof NetworkError) {
    console.log('Network issue:', error.message);
  }
}
