Account

Both Direct Inference and Fine-tuning use the same per-provider account system: you deposit to a main account, transfer funds to each provider's sub-account, and the provider deducts from there as you use the service. This page is the shared reference for all operations — Web UI, CLI, and SDK.

Using the Router instead?

The Router has its own unified billing and does not use per-provider sub-accounts. Router deposits, balance, API keys, and usage live elsewhere — see Router → Deposits & Billing and Router → Authentication.

Overview

The account system provides a secure and flexible way to manage funds across different AI service providers.

Account Structure

• Main Account: Your primary wallet where funds are deposited. All deposits go here first, and you can withdraw funds from here back to your wallet.
• Sub-Accounts: Provider-specific accounts created automatically when you transfer funds to a provider. Each provider has a separate sub-account where funds are locked for their specific services.

Fund Flow

1. Deposit: Transfer funds from your wallet to your Main Account
2. Transfer: Move funds from Main Account to Provider Sub-Accounts
3. Usage: Provider deducts from Sub-Account for services rendered
4. Refund Request: Initiate refund from Sub-Account (enters 24-hour lock period)
5. Complete Refund: After lock period expires, call retrieve-fund again to complete transfer back to Main Account
6. Withdraw: Transfer funds from Main Account back to your wallet

Security Features

• 24-hour lock period for refunds to protect providers from abuse
• Single-use authentication for each request to prevent replay attacks
• On-chain verification for all transactions ensuring transparency
• Provider acknowledgment required before first use of services

Prerequisites

• Node.js >= 20.0.0
• A wallet with 0G tokens (for testnet or mainnet)
• EVM compatible wallet (for Web UI)

Transfer to Provider

Before using a provider's service, transfer funds to their sub-account:

0g-compute-cli transfer-fund --provider <PROVIDER_ADDRESS> --amount 5

Request Refund

Withdraw unused funds from sub-accounts back to main account:

0g-compute-cli retrieve-fund

Note: Refunds have a 24-hour lock period for security. After the lock period expires, you need to call this function again to complete the refund and transfer the funds back to your main account. You can check the remaining lock time using the get-sub-account command:

0g-compute-cli get-sub-account --provider <PROVIDER_ADDRESS>

Example output showing refund details:

Withdraw to Wallet

Withdraw funds from main account to your wallet:

0g-compute-cli refund --amount 5

SDK

Best for: Application integration and programmatic access

Installation

pnpm add @0gfoundation/0g-compute-ts-sdk

Initialize Broker

import { ethers } from "ethers";
import { createZGComputeNetworkBroker } from "@0gfoundation/0g-compute-ts-sdk";

const provider = new ethers.JsonRpcProvider("https://evmrpc-testnet.0g.ai");
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
const broker = await createZGComputeNetworkBroker(wallet);

Check Account Balance

const account = await broker.ledger.getLedger();
console.log(`Total Balance: ${ethers.formatEther(account.totalBalance)} 0G`);
console.log(`Available: ${ethers.formatEther(account.availableBalance)} 0G`);

Deposit Funds

await broker.ledger.depositFund(10); // Deposit 10 0G

Transfer to Provider

const providerAddress = "<PROVIDER_ADDRESS>";
const amount = ethers.parseEther("5"); // 5 0G
await broker.ledger.transferFund(providerAddress, "inference", amount);

Check Sub-Account Details

const [subAccount, refunds] = await broker.inference.getAccountWithDetail(providerAddress);
console.log(`Sub-account balance: ${ethers.formatEther(subAccount.balance)} 0G`);

const { account: subAccount, refunds } = await broker.fineTuning.getAccountWithDetail(providerAddress);
console.log(`Sub-account balance: ${ethers.formatEther(subAccount.balance)} 0G`);

Request Refund

await broker.ledger.retrieveFund("inference");
await broker.ledger.retrieveFund("fine-tuning");

Withdraw to Wallet

await broker.ledger.refund(5); // Withdraw 5 0G

Best Practices

For Inference Services

1. Deposit enough funds for expected usage
2. Transfer funds to providers you plan to use frequently
3. Keep some balance in sub-accounts for better response times
4. Monitor usage regularly

For Fine-tuning Services

1. Calculate dataset size before transferring funds
2. Transfer enough to cover the entire training job
3. Request refunds for unused funds after job completion

Troubleshooting

Insufficient Balance Error

Check which account needs funds:

• Main account: Use deposit
• Sub-account: Use transfer-fund

# Check all balances
0g-compute-cli get-account

# Deposit to main account if needed
0g-compute-cli deposit --amount 10

# Transfer to provider if needed
0g-compute-cli transfer-fund --provider <ADDRESS> --amount 5

Refund Not Available

Refunds have a 24-hour lock period. After the lock period expires, you need to call the retrieve-fund function again to complete the refund. Check the status:

0g-compute-cli get-sub-account --provider <PROVIDER_ADDRESS>

Look for "Remaining Locked Time" in the output.

Transaction Failed

Common causes:

1. Network issues - Check your RPC endpoint
2. Gas price too low - Increase gas price
3. Insufficient gas - Ensure wallet has enough for gas fees

# Specify custom gas price
0g-compute-cli deposit --amount 10 --gas-price 20000000000
