Coinbase Python API - Basic Example

Here's a basic example of using the Coinbase Python API to check the price of a cryptocurrency and place buy or sell orders. This requires the coinbase Python library, which you can install via pip install coinbase.

Note: Replace 'API_KEY' and 'API_SECRET' with your actual API key and secret, which you can create on your Coinbase account under API settings. Make sure your API key has the appropriate permissions for trading.

Setup

# Install the Coinbase library
!pip install coinbase

Import Libraries and Set Up API Client

from coinbase.wallet.client import Client

# Initialize the client
API_KEY = 'YOUR_API_KEY'
API_SECRET = 'YOUR_API_SECRET'
client = Client(API_KEY, API_SECRET)

Check Price

def check_price(currency_pair='BTC-USD'):
    price = client.get_spot_price(currency_pair=currency_pair)
    print(f"The current price of {currency_pair} is: {price['amount']} {price['currency']}")
    return price['amount']

# Check price of Bitcoin in USD
check_price()

Place a Buy Order

def place_buy_order(amount, currency='BTC', currency_pair='BTC-USD'):
    buy = client.buy(
        account_id='YOUR_ACCOUNT_ID',  # Replace with your Coinbase account ID for the asset
        amount=amount,
        currency=currency,
        payment_method='YOUR_PAYMENT_METHOD_ID'  # Replace with your payment method ID
    )
    print(f"Placed a buy order for {amount} {currency}. Transaction details:", buy)
    return buy

# Example: Buy 0.001 BTC
place_buy_order(0.001)

Place a Sell Order

def place_sell_order(amount, currency='BTC', currency_pair='BTC-USD'):
    sell = client.sell(
        account_id='YOUR_ACCOUNT_ID',  # Replace with your Coinbase account ID for the asset
        amount=amount,
        currency=currency,
        payment_method='YOUR_PAYMENT_METHOD_ID'  # Replace with your payment method ID
    )
    print(f"Placed a sell order for {amount} {currency}. Transaction details:", sell)
    return sell

# Example: Sell 0.001 BTC
place_sell_order(0.001)

Notes:

1. Account ID: You can find your account ID in your Coinbase account or by using the client.get_accounts() method.
2. Payment Method ID: Required for placing trades, find it by using client.get_payment_methods().

This code allows checking prices and executing basic buy/sell orders. Make sure to test in a controlled environment or use a sandbox API if available, as transactions in live mode affect real funds.
