Python Crypto.com SDK

A Python wrapper for the crypto.com Exchange REST API v1.

Installation

pip install python_crypto_dot_com_sdk

Setup

All private endpoints (trading, account balance, order history) require an API key and secret from your crypto.com Exchange account.

from crypto_dot_com.client import CryptoAPI

client = CryptoAPI(
    api_key="YOUR_API_KEY",
    api_secret="YOUR_API_SECRET",
)

Optional parameters:

Parameter	Default	Description
timeout	1000	Request timeout in ms
log_json_response_to_file	False	Save raw API responses as JSON files
logs_directory	None	Directory for JSON logs (current dir if None)

Enable response logging when debugging or auditing API calls:

client = CryptoAPI(
    api_key="YOUR_API_KEY",
    api_secret="YOUR_API_SECRET",
    log_json_response_to_file=True,
    logs_directory="logs/",
)

Market Data

Market data is public — no API credentials are required.

Get recent candlesticks

Use this to fetch the most recent OHLCV (Open, High, Low, Close, Volume) candles for a trading pair. Suitable for displaying a price chart or feeding a real-time strategy.

candles = client.get_candlesticks(
    instrument_name="BTC_USD",
    timeframe="1h",   # see intervals below
    count=100,        # number of candles (max 300)
)

for c in candles:
    print(c.datetime, c.open, c.high, c.low, c.close, c.volume)

Available timeframes (CandlestickTimeInterval):

Value	Enum name	Period
"1m"	MIN_1	1 minute
"5m"	MIN_5	5 minutes
"15m"	MIN_15	15 minutes
"30m"	MIN_30	30 minutes
"1h"	HOUR_1	1 hour
"2h"	HOUR_2	2 hours
"4h"	HOUR_4	4 hours
"12h"	HOUR_12	12 hours
"1D"	DAY_1	1 day
"7D"	DAY_7	7 days
"14D"	DAY_14	14 days
"1M"	MONTH_1	1 month

Download full historical candlestick data

Use this to build a local dataset for backtesting or analysis. The method automatically walks backwards in time, making repeated API calls until no more data is available (or until min_datetime is reached).

import datetime
import pytz

candles = client.get_all_candlesticks(
    instrument_name="BTC_USD",
    interval="1D",                        # daily candles
    verbose=True,                         # print progress
)

# Limit the date range
candles = client.get_all_candlesticks(
    instrument_name="ETH_USD",
    interval="1h",
    min_datetime=datetime.datetime(2024, 1, 1, tzinfo=pytz.UTC),
    max_datetime=datetime.datetime(2024, 6, 1, tzinfo=pytz.UTC),
    verbose=False,
)

# Save to JSON
import json
with open("btc_daily.json", "w") as f:
    json.dump([c.model_dump() for c in candles], f, indent=2, default=str)

When to use get_candlesticks vs get_all_candlesticks:

• get_candlesticks — live dashboards, recent data, or when you know the exact time window.
• get_all_candlesticks — one-time historical downloads or building a full dataset for backtesting.

Portfolio & Balance

View your current holdings

Returns your portfolio as a list of positions, one per currency held.

# As a list of xarizmi PortfolioItem objects
items = client.get_user_balance_summary()
for item in items:
    print(item.symbol.base_currency.name, item.quantity, item.market_value)

# As a xarizmi Portfolio object (useful with the xarizmi ecosystem)
portfolio = client.get_current_portfolio()

# As a pandas DataFrame (useful for quick analysis or export)
df = client.get_user_balance_summary_as_df()
print(df[["symbol", "market_value", "portfolio_percentage"]])

The DataFrame is sorted by market_value descending and includes:

Column	Description
symbol	Currency name (e.g. BTC)
quantity	Amount held
market_value	USD market value
exchange	Always crypto.com
portfolio_percentage	Fraction of total portfolio (0–1)
date	Today's date

Optional flags:

df = client.get_user_balance_summary_as_df(
    include_portfolio_percentage=False,
    include_date=False,
)

Use get_user_balance_summary_as_df when you want to quickly inspect or export your holdings. Use get_current_portfolio when integrating with the xarizmi framework (e.g. for portfolio ratio analysis).

Order Management

Place a limit buy order

A limit order lets you specify the exact price at which you want to buy. The order sits in the order book until it is filled or cancelled.

# Returns a simple object with order_id and client_oid
order = client.create_limit_order(
    instrument_name="CRO_USD",
    quantity=1000,
    side="BUY",
    price=0.12,
)
print(order.order_id)

# Returns a xarizmi Order (preferred when using the xarizmi ecosystem)
order = client.create_buy_limit_order_xarizmi(
    instrument_name="CRO_USD",
    quantity=1000,
    price=0.12,
)

Place a limit sell order

order = client.create_sell_limit_order_xarizmi(
    instrument_name="CRO_USD",
    quantity=1000,
    price=0.15,
)

create_limit_order vs create_buy/sell_limit_order_xarizmi:

• create_limit_order returns only the order_id and client_oid from the API response. Use it when you just need to fire and record the ID.
• create_buy_limit_order_xarizmi / create_sell_limit_order_xarizmi return a fully populated xarizmi Order object (with symbol, price, quantity, side, and status). Use these when you want to track the order in your own data model.

Cancel orders

# Cancel a specific order
client.cancel_order(order_id="11111000000000000001")

# Cancel all open orders for an instrument (asynchronous — confirmation only)
client.cancel_all_orders(instrument_name="CRO_USD")

# Cancel all open orders across all instruments
client.cancel_all_orders()

Note: cancel_all_orders is asynchronous on the exchange side. The call returns immediately after the request is accepted, not after the orders are actually cancelled. Wait briefly and check order status if you need confirmation.

Error handling for order placement

The API returns specific error codes that are mapped to Python exceptions:

from crypto_dot_com.exceptions import BadPriceException, BadQuantityException

try:
    client.create_limit_order("CRO_USD", quantity=1000, side="BUY", price=0.0)
except BadPriceException:
    print("Price was rejected by the exchange (too low, too high, or zero)")
except BadQuantityException:
    print("Quantity was rejected (below minimum or invalid)")
except RuntimeError as e:
    print(f"Unexpected API error: {e}")

Order History & Status

Check the status of a specific order

Use this to poll whether an order has been filled, is still active, or was cancelled. Common in automated trading loops.

# Raw response (crypto.com data model)
order = client.get_order_details(order_id="11111000000000000001")
print(order.status)          # ACTIVE | FILLED | CANCELED | REJECTED | EXPIRED
print(order.avg_price)       # average fill price
print(order.cumulative_quantity)  # how much has been filled so far

# xarizmi Order (maps status to xarizmi OrderStatusEnum)
order = client.get_order_details_in_xarizmi(order_id="11111000000000000001")
print(order.status)   # OrderStatusEnum.ACTIVE | DONE | CANCELLED
print(order.price)    # computed as order_value / quantity

Fetch order history for a time range

Use this to review what trades were executed. The client automatically handles pagination — if the API returns the maximum number of records, it splits the time range and recurses until all orders are retrieved.

# Timestamps in nanoseconds
orders = client.get_order_history(
    start_time=1_704_067_200_000_000_000,
    end_time=1_704_153_600_000_000_000,
    instrument_name="BTC_USD",   # omit to get all instruments
)

# Convenience wrapper for a single calendar day
import datetime
orders = client.get_all_order_history_of_a_day(
    day=datetime.date(2024, 6, 15),
    instrument_name="CRO_USD",
)

for o in orders:
    print(o.order_id, o.side, o.status, o.avg_price, o.cumulative_quantity)

Limit: Crypto.com allows retrieving order history up to 6 months in the past. Run export_order_history (see below) regularly to maintain a longer local record.

Export Utilities

The crypto_dot_com.export module provides standalone functions for downloading and persisting data without managing a CryptoAPI instance directly.

Export order history to CSV

Downloads order history and saves it to a CSV file. If the file already exists, new records are merged and duplicates (by order_id) are removed — so you can run this daily as an incremental update.

from crypto_dot_com.export import export_order_history

# Download today's orders and append to existing file
n_records = export_order_history(
    api_key="YOUR_API_KEY",
    secret_key="YOUR_API_SECRET",
    filepath="orders.csv",
    past_n_days=0,     # 0 = today only; 7 = today + last 7 days
)
print(f"Total records in file: {n_records}")

Read and filter a saved CSV

from crypto_dot_com.export import read_order_history_from_csv
from crypto_dot_com.enums import StatusEnum

# Load as list of OrderHistoryDataMessage objects
orders = read_order_history_from_csv(
    filepath="orders.csv",
    filter_by_status=[StatusEnum.FILLED],
    filter_by_instrument_name="BTC_USD",
)

# Load as a DataFrame instead
df = read_order_history_from_csv(
    filepath="orders.csv",
    filter_by_status=["FILLED", "CANCELED"],
    return_type="dataframe",
)

Export portfolio snapshot to CSV and pie chart

Takes a snapshot of your current holdings and saves it to CSV. Optionally generates a pie chart of your portfolio allocation.

from crypto_dot_com.export import export_user_balance

export_user_balance(
    api_key="YOUR_API_KEY",
    secret_key="YOUR_API_SECRET",
    filepath="portfolio.csv",
    pie_chart_filepath="portfolio.svg",   # omit to skip the chart
    figsize=(10, 10),
)

Tip: Schedule export_order_history and export_user_balance to run daily (e.g. with cron or a scheduler) to build a long-term record of your trading activity and portfolio performance.

Instrument names

Crypto.com uses BASE_QUOTE format for instrument names:

BTC_USD    — Bitcoin priced in USD
ETH_USDT   — Ethereum priced in USDT
CRO_USD    — Cronos priced in USD

Pass these strings as-is to any method that accepts instrument_name.

---

Integration with xarizmi

Methods suffixed with _xarizmi return objects from the xarizmi framework, which provides a unified data model for portfolio management across exchanges. Use these when you want to:

• Compare portfolios across exchanges
• Use xarizmi's portfolio ratio analysis (portfolio / past_portfolio)
• Store orders and candles in xarizmi's database via CryptoDbApiClient (see crypto_dot_com/client_db.py)
