Installation

pip install cbadvanced

Or with your preferred package manager:

# Using uv
uv add cbadvanced

# Using poetry
poetry add cbadvanced

Quick Start

Getting API Credentials

1. Go to Coinbase Developer Platform
2. Create a new API key with "Advanced Trade" permissions
3. Save your API key name and private key (PEM format)

Synchronous Usage

from cbadvanced import Client

# Your API credentials
API_KEY = "organizations/your-org/apiKeys/your-key"
API_SECRET = """-----BEGIN EC PRIVATE KEY-----
YOUR PRIVATE KEY HERE
-----END EC PRIVATE KEY-----"""

with Client(key=API_KEY, secret=API_SECRET) as client:
    # Get all products
    products = client.get_products()
    for product in products:
        print(f"{product.product_id}: ${product.price}")

    # Get account balances
    accounts = client.get_accounts()
    for account in accounts:
        if float(account.available_balance.value) > 0:
            print(f"{account.currency}: {account.available_balance.value}")

Asynchronous Usage

import asyncio
from cbadvanced import AsyncClient

async def main():
    async with AsyncClient(key=API_KEY, secret=API_SECRET) as client:
        # Get BTC-USD price
        product = await client.get_product("BTC-USD")
        print(f"BTC-USD: ${product.price}")

        # Get recent candles
        candles = await client.get_candles("BTC-USD")
        for candle in candles[:5]:
            print(f"Open: {candle['open']}, Close: {candle['close']}")

asyncio.run(main())

API Reference

Client Initialization

Both Client and AsyncClient accept the same parameters:

Client(
    key: str,           # API key name
    secret: str,        # PEM-encoded private key
    timeout: float = 30.0  # Request timeout in seconds
)

Account Methods

# Get all accounts (wallets)
accounts = client.get_accounts(limit=250, cursor=None)

# Get a specific account
account = client.get_account(account_id="your-account-uuid")

Product Methods

# Get all tradeable products
products = client.get_products(product_type="SPOT", limit=None)

# Get a specific product
product = client.get_product("BTC-USD")

# Get historical candles (OHLCV data)
from cbadvanced import Granularity
from datetime import datetime, timedelta

candles = client.get_candles(
    "BTC-USD",
    start=datetime.now() - timedelta(days=7),  # or Unix timestamp
    end=datetime.now(),                         # or Unix timestamp
    granularity=Granularity.ONE_HOUR
)

# Get recent market trades
trades = client.get_market_trades("BTC-USD", limit=100)
print(f"Best bid: {trades.best_bid}, Best ask: {trades.best_ask}")

Order Methods

from cbadvanced import OrderSide

# Create a limit order
response = client.create_order(
    product_id="BTC-USD",
    side=OrderSide.BUY,  # or "BUY"
    order_type="limit",
    size="0.001",        # Amount in base currency (BTC)
    price="50000.00"     # Limit price in quote currency (USD)
)

if response.success:
    print(f"Order created: {response.order_id}")

# Create a market order
response = client.create_order(
    product_id="BTC-USD",
    side=OrderSide.BUY,
    order_type="market",
    size="100.00"  # Amount in quote currency (USD) for market orders
)

# Get historical orders
orders = client.get_orders(
    product_id="BTC-USD",      # Optional: filter by product
    order_status=["FILLED"],   # Optional: filter by status
    limit=100
)

# Get a specific order
order = client.get_order("order-id-here")

# Cancel orders
result = client.cancel_orders(["order-id-1", "order-id-2"])
for r in result.results:
    print(f"Order {r.order_id}: {'Cancelled' if r.success else r.failure_reason}")

Fill Methods

# Get trade fills (executed orders)
fills = client.get_fills(
    product_id="BTC-USD",  # Optional
    order_id="order-123",  # Optional
    limit=100
)

for fill in fills:
    print(f"Trade {fill.trade_id}: {fill.size} @ ${fill.price}")

    CoinbaseAPIError,     # API returned an error (4xx, 5xx)
    CoinbaseAuthError,    # Authentication failed
    CoinbaseRequestError, # Request/network error
)

try:
    product = client.get_product("INVALID-PRODUCT")
except CoinbaseAPIError as e:
    print(f"API Error {e.status_code}: {e.message}")
    print(f"Error code: {e.error_code}")
    print(f"Details: {e.details}")
except CoinbaseRequestError as e:
    print(f"Request failed: {e.message}")
