BEST PRACTICES

The CryptoMarket API development team strives to bring the best trading experience to API users. This manual contains a set of best practices for using the API as efficiently as possible.

HTTP Persistent Connection

The underlying TCP connection is kept active for multiple requests/responses. Subsequent requests will result in reduced latency as the TCP handshaking process is no longer required.

If you use the HTTP 1.0 client, please ensure it supports the Keep-Alive directive and submit the ''Connection: Keep-Alive'' header with your request.

Keep-Alive is a part of the HTTP 1.1 protocol and enabled by default on compliant clients. However, you will have to ensure your implementation does not set other values as the connection header.

Retrieving and updating account state

Use the Streaming API for real-time updates of your orders, trades and any transaction changes.

REST API Reference

HTTP Status codes

Authentication

curl -u "publicKey:secretKey" https://api.exchange.cryptomkt.com/api/2/trading/balance
import requests
session = requests.session()
session.auth = ("publicKey", "secretKey")

const fetch = require('node-fetch');

const credentials = Buffer.from('publicKey' + ':' + 'secretKey').toString('base64');

fetch('https://api.exchange.cryptomkt.com/api/2/trading/balance', {
    method: 'GET',
    headers: {
        'Authorization': 'Basic ' + credentials
    }
});

Public market data are available without authentication. Authentication is required for other requests.

You should create API keys on the API Settings page. You can create multiple API keys with different access rights for your applications.

Use Basic Authentication to access the REST API.

Authentication HS256

import requests
from requests.auth import AuthBase
from urllib.parse import urlparse
from base64 import b64encode
import hmac
import hashlib
import time


class HS256(AuthBase):
    def __init__(self, username, password):
        self.username = username
        self.password = password

    def __call__(self, r):
        url = urlparse(r.url)
        timestamp = str(int(time.time()))
        msg = r.method + timestamp + url.path
        if url.query != "":
            msg += "?" + url.query
        if r.body:
            msg += r.body

        signature = hmac.new(self.password.encode(), msg.encode(), hashlib.sha256).hexdigest()
        authstr = "HS256 " + b64encode(
                    b':'.join((self.username.encode(), timestamp.encode(), signature.encode()))).decode().strip()

        r.headers['Authorization'] = authstr
        return r

session = requests.session()
session.auth = HS256("publicKey", "secretKey")

balance = session.get("https://api.exchange.cryptomkt.com/api/2/trading/balance").json()
# or without session
balance = requests.get("https://api.exchange.cryptomkt.com/api/2/trading/balance", auth=HS256("publicKey", "secretKey")).json()

The alternative authentication method is the HMAC signature.

You should set header Authorization with publicKey and signature base64 encoded:

  1. Create hmac signature with secretKey as a key and sign request "method+timestamp+url+body"
  2. Like as basic authorization add header "Authorization: HS256 " + base64(publicKey+":"+timestamp+":"+signature hex encoded)

POST /api/2/order
PUT /api/2/order/{clientOrderId}

Requires the "Place/cancel orders" API key Access Right.

Price accuracy and quantity

Symbol config contains the tickSize parameter which means that price should be divided by tickSize with no remainder.
quantity should be divided by quantityIncrement with no remainder.
By default, if strictValidate is not enabled, the Server rounds half down the price and quantity for tickSize and quantityIncrement.

Example of ETHBTC: tickSize = '0.000001', then price '0.046016' is valid, '0.0460165' is invalid.

Fees

Charged fee is determined in symbol's feeCurrency. Maker-taker fees offer a transaction rebate provideLiquidityRate to those who provide liquidity (the market maker), while charging customers who take that liquidity takeLiquidityRate.

To create buy orders, you must have sufficient balance including fees.
Available balance > price * quantity * (1 + takeLiquidityRate)

Order result status

For orders with timeInForce = IOC or FOK, the REST API returns final order state: filled or expired.

If order can be instantly executed, then the REST API returns a status of filled or partiallyFilled in the order's info.

Parameters:

Name Type Description
clientOrderId String Optional parameter.
If it is skipped, it will be generated by the Server. Uniqueness must be guaranteed within a single trading day, including all active orders.
symbol String Trading symbol
side String Trade side
Accepted values: sell or buy
type String Optional parameter
Accepted values: limit, market, stopLimit, stopMarket
Default value: limit
timeInForce String Optional parameter
Accepted values: GTC, IOC, FOK, Day, GTD
Default value: GTC
quantity Number Order quantity
price Number Order price. Required for limit order types
stopPrice Number Required for stop-limit and stop-market orders
expireTime Datetime Required for orders with timeInForce = GTD
strictValidate Boolean Price and quantity will be checked for incrementation within the symbol’s tick size and quantity step. See the symbol's tickSize and quantityIncrement.
postOnly Boolean If your post-only order causes a match with a pre-existing order as a taker, then the order will be cancelled.
takeLiquidityMarkup Number Optional liquidity taker fee, a fraction of order volume, such as 0.001 (for 0.1% fee)
provideLiquidityMarkup Number Optional liquidity provider fee, a fraction of order volume, such as 0.001 (for 0.1% fee)

{
  "method": "newOrder",
  "params": {
    "clientOrderId": "57d5525562c945448e3cbd559bd068c4",
    "symbol": "ETHBTC",
    "side": "sell",
    "price": "0.059837",
    "quantity": "0.015"
  },
  "id": 123
}

An RPC call is represented by sending a Request object to a Server.

The Request object has the following members:

Notification

{
  "jsonrpc": "2.0",
  "method": "updateTrades",
  "params": {
    "data": [
      {
        "id": 54469813,
        "price": "0.054670",
        "quantity": "0.183",
        "side": "buy",
        "timestamp": "2017-10-19T16:34:25.041Z"
      }
    ],
    "symbol": "ETHBTC"
  }
}    

A Notification is a Request object without an id member. A Request object (a Notification) signifies the lack of the Client's interest in the corresponding Response object. Therefore no Response objects need to be returned to the Client.

The Notification object has the following members:

Response object

When RPC call is made, the Server MUST reply with a Response, except for Notifications cases.

Socket Account Management

Description

WebSocket Account API uses the same authorization approach as described in the Socket Session Authentication section.

API provides the following tools to manage a general account:

Subscription to the transactions

Method: subscribeTransactions and the corresponding unsubscription method: unsubscribeTransactions

Income method: updateTransaction

A full transaction model description can be found in the "Get Transactions History" section.

A subscription to the transactions has to be used rather than transaction polling.

A transaction notification occurs each time the transaction has been changed: such as creating a transaction, updating the pending state (for example the hash assigned) or completing a transaction. This is the easiest way to track deposits or develop real-time asset monitoring.

A combination of the recovery mechanism and transaction subscription provides reliable and consistent information regarding transactions. For that, you should store the latest processed index and requested possible gap using a "loadTransactions" method after connecting or reconnecting the Websocket.

Subscription request:

{"method": "subscribeTransactions", "jsonrpc": "2.0", "params": {}, "id": 7652}

Subscription result:

{"jsonrpc":"2.0","result":true,"id": 7652}

    "updatedAt": "2021-01-31T08:19:33.967Z"
  }
}

Subscription to the balance

Method: subscribeBalance and the corresponding unsubscription method: unsubscribeBalance

Income method: balance

This subscription aims to provide an easy way to be informed of the current balance state. If the state has been changed or potentially changed the "balance" event will come with the actual state. Please be aware that only non-zero values present.

Event "balance" arrives after each successful subscription.

Guide & Code Samples

Fetch all public trades

Fetch all trades history for a symbol and keep it updated.

General idea: the fetch trades are sorted by ASC from latest id.

import requests
import time
session = requests.session()


def get_trades(symbol_code, from_id):
    return session.get("https://api.exchange.cryptomkt.com/api/2/public/trades/%s?sort=ASC&by=id&from=%d&limit=1000" % (symbol_code, from_id)).json()


symbol = 'ETHDAI'
from_trade_id = 1

while True:
    trades = get_trades(symbol, from_trade_id)
    if len(trades) > 0:
        from_trade_id = trades[-1]['id'] + 1
        print('Loaded trades till', trades[-1]['id'], trades[-1]['timestamp'])
        if len(trades) < 1000:
            time.sleep(5)
    else:
        time.sleep(30)

Get trades updated

First version

The fastest way is use the socket API. Subscribe for reports (method subscribeReports) and handle reportType == trade.

Second version

Fetch trades as in the example above but with small changes.

import requests
import time
session = requests.session()
session.auth = ("publicKey", "secretKey")

def get_my_trades(from_id):
    return session.get("https://api.exchange.cryptomkt.com/api/2/history/trades?sort=ASC&by=id&limit=100&from=%d" % (from_id)).json()

def get_recent_my_trades():
    return session.get("https://api.exchange.cryptomkt.com/api/2/history/trades?sort=DESC&by=id&limit=10").json()

from_trade_id = 0

while True:
    if from_trade_id == 0:
        recent_trades = get_recent_my_trades()
        if len(recent_trades) > 0:
            from_trade_id = recent_trades[0]['id'] + 1
            print('Last recent trade', recent_trades[0])
        else:
            print('You do not have any trades')
    else:
        trades = get_my_trades(from_trade_id)
        if len(trades) > 0:
            from_trade_id = trades[-1]['id'] + 1
            print('new trades', trades)
        else:
            print('No new trades')
    time.sleep(30)

Getting new transactions

The code in the example allows you to get all of your new deposits, withdrawals and transfers.

The index is a 64-bit integer, that increases on any transaction update. To get all new updates of transactions you will need to request transactions with an index value which is greater than the latest one.

For example, if you have created a withdrawal, then you get an update with a transaction hash and committed status after receiving the required number of confirmations.

import requests
import time
session = requests.session()
session.auth = ("publicKey", "secretKey")

def get_my_transactions(from_index):
    return session.get("https://api.exchange.cryptomkt.com/api/2/account/transactions?sort=ASC&by=index&limit=100&from=%d" % (from_index)).json()

def get_recent_my_transactions():
    return session.get("https://api.exchange.cryptomkt.com/api/2/account/transactions?sort=DESC&by=index&limit=100").json()

from_index = 0

while True:
    if from_index == 0:
        recent_transactions = get_recent_my_transactions()
        if len(recent_transactions) > 0:
            from_index = recent_transactions[0]['index'] + 1
            print('Last recent trade', recent_transactions[0])
        else:
            print('You do not have any transactions')
    else:
        transactions = get_my_transactions(from_index)
        if len(transactions) > 0:
            from_index = transactions[-1]['index'] + 1
            print('New and Updated transactions', transactions)
        else:
            print('No new updates')
    time.sleep(60)
