Prerequisites
- Python 3.13
- VSCode with Python extension
๐ Ready to automate your crypto tracking? Try OKX API now!
Method 1: Manual Signature Approach
1. Setting Up the Development Environment
- Install required libraries:
bash
pip3 install requests - Verify installation:
bash
python3 -c "import requests; print(requests.__version__)"
2. Obtaining OKX API Keys
- Log in to OKX โ Profile โ API โ Create API Key
- Set permissions: “Read Account Information”
- Note your:
- API Key
- Secret Key
- Passphrase
3. Creating the Python Script
- Create a file
okx_balance.py - Insert the following code (replace placeholder credentials):
“`python
import requests
import time
import hashlib
import hmac
import base64
API configuration
API_KEY = “your_api_key”
SECRET_KEY = “your_secret_key”
PASSPHRASE = “your_passphrase”
“`

Common Issues & Solutions (Manual Method)
| Error Code | Cause | Solution |
|---|---|---|
| 50101 | Incorrect API credentials | Verify key permissions and character cases |
| 50113 | Connection failure | Test connectivity to OKX’s public endpoints first |
| 50114 | Invalid timestamp | Sync local clock with OKX server time |
Method 2: Python SDK Approach
1. Installation
bash
pip3 install okx
2. Modified Working Code
“`python
from okx.app.account import AccountSPOT # Critical import modification
def get_balance():
config = {
‘api_key’: ‘your_key’,
‘secret_key’: ‘your_secret’,
‘passphrase’: ‘your_phrase’
}
account = AccountSPOT(**config)
return account.get_balances()
“`
SDK Troubleshooting
Issue: Rust Compilation Errors
- Install Rust:
bash
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh - Restart terminal and reinstall SDK
FAQ Section
Q: Which method is better for beginners?
A: The SDK approach requires fewer cryptographic steps but may need Rust installation.
Q: How often can I call the balance API?
A: OKX rate limits apply – typically 20 requests per 2 seconds.
Q: Is my API key exposed in the script?
A: Never hardcode keys in production. Use environment variables instead.
Q: Why does my timestamp keep failing?
A: OKX requires UTC timestamps with โค30s deviation. Consider NTP synchronization.
Q: Can I use this for trading automation?
A: Yes, but you’ll need additional “Trade” permissions in your API key.
Q: Where can I find complete API documentation?

Key Takeaways
- Always secure your API credentials
- Prefer the SDK method for maintainability
- Monitor API rate limits
- Regularly update dependencies
- Test with small requests before production use
This guide covers essential techniques for integrating OKX’s API with Python while addressing common pain points developers encounter. For enterprise-grade implementations, consider additional error handling and logging.
