Quick start

Prerequisites

Step 1: Register an account on OKX and apply for an API key

• Register for an account: https://www.okx.com/account/register
• Apply for an API key: https://www.okx.com/account/users/myApi

Step 2: Install python-okx

pip install python-okx

API Credentials

Option 1: Hardcoded credentials

from okx import Account

account = Account.AccountAPI(
    api_key="your-api-key-here",
    api_secret_key="your-api-secret-here",
    passphrase="your-passphrase-here",
    flag="1",  # 0 = live trading, 1 = demo trading
    debug=False
)

Option 2: Using .env file (recommended)

Create a .env file in your project root:

OKX_API_KEY=your-api-key-here
OKX_API_SECRET=your-api-secret-here
OKX_PASSPHRASE=your-passphrase-here
OKX_FLAG=1

Then load it in your code:

import os
from dotenv import load_dotenv
from okx import Account

load_dotenv()

account = Account.AccountAPI(
    api_key=os.getenv('OKX_API_KEY'),
    api_secret_key=os.getenv('OKX_API_SECRET'),
    passphrase=os.getenv('OKX_PASSPHRASE'),
    flag=os.getenv('OKX_FLAG', '1'),
    debug=False
)
