All timestamps are returned in ISO 8601 format (UTC).
Example: "2017-04-03T10:20:49.315Z"

Number Format

All finance data, e.g. price, quantity, fee, etc., should be arbitrary precision numbers and have a string representation.
Example: "10.2000058"

Pagination

Parameters:

Parameter	Description
limit	Number of results per call Accepted range: 0 - 1000 Default value: 100
offset	Number of results offset Default value: 0
sort	Sort direction Accepted values: ASC (ascending order), DESC (descending order) Default value: DESC
by	Defines filter type Accepted values: id, timestamp
from	Interval initial value (optional parameter) If filter by timestamp is used, then parameter type is datetime, otherwise object id

RATE LIMITING

The following Rate Limits are applied:

• For the Market data, the limit is 100 requests per second for one IP;
• For Trading, the limit is 300 requests per second for one user;
• For other requests, including Trading history, the limit is 10 requests per second for one user.

Significantly exceeding the Rate Limits can lead to suspension.

BEST PRACTICES

The BEQUANT 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

• 200 OK. Successful request
• 400 Bad Request. Returns JSON with the error message
• 401 Unauthorized. Authorization is required or has been failed
• 403 Forbidden. Action is forbidden for API key
• 429 Too Many Requests. Your connection has been rate limited
• 500 Internal Server. Internal Server Error
• 503 Service Unavailable. Service is down for maintenance
• 504 Gateway Timeout. Request timeout expired

Error response

All error responses have error code and human readable message fields. Some errors contain an additional description field.

Example of error response:

{
  "error": {
    "code": 20001,
    "message": "Insufficient funds",
    "description": "Check that the funds are sufficient, given commissions"
  }

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

You should create API keys on the API Setting 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.bequant.io/api/2/trading/balance").json()
# or without session
balance = requests.get("https://api.bequant.io/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.

Response: order

Socket API Reference

Use JSON-RPC 2.0 over WebSocket connection as transport.

Request object

{
  "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:

• method - a String containing the name of the method to be invoked.
• params - a Structured value that holds the parameter values to be used during the invocation of the method.
• id - An identifier established by the Client that MUST contain a String, Number, or NULL value if included. If it is not included it is assumed to be a notification. The value SHOULD NOT be Null.

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:

• method - a string containing the name of the method to be invoked.
• params - a structured value holding the parameter values to be used during the method invocation.

Response object

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

Server responses for each request. Response on success subscription is true. Example:

{
  "jsonrpc": "2.0",
  "result": true,
  "id": 123
}

Response error

{
  "jsonrpc": "2.0",
  "error": {
    "code": 2001,
    "message": "Symbol not found",
    "description": "Try get /api/2/public/symbol, to get list of all available symbols."
  },
  "id": 123
}

The Response is represented as a single JSON Object, with the following members:

• result - this member is REQUIRED on success. This member MUST NOT exist if there was an error during method invocation. The value of this member is determined by the method invoked on the Server.
• error - this member is REQUIRED on error. This member MUST NOT exist if there was no error triggered during method invocation. The value for this member MUST be an Object as defined in the Error response section.

Socket Market Data

The parameters of requests, responses, and errors correspond to REST, but have different usage procedures.
First, you should subscribe for the required data. Then the Server will send a full snapshot of the data. After that, the Server sends an update notification.

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 = ('3ef4a9f8c8bf04bd8f09884b98403eae', '2deb570ab58fd553a4ed3ee249fd2d51')

def get_my_trades(from_id):
    return session.get("https://api.bequant.io/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.bequant.io/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 = ('3ef4a9f8c8bf04bd8f09884b98403eae', '2deb570ab58fd553a4ed3ee249fd2d51')

def get_my_transactions(from_index):
    return session.get("https://api.bequant.io/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.bequant.io/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)
