API Explorer
You can explore the API using SwaggerUI including methods requiring authorization.
DateTime Format
All timestamps are returned in ISO 8601 format or UNIX timestamp in milliseconds (UTC).
Example: "2021-06-03T10:20:49.315Z" or "1614815872000".
Date Format
Some timestamps are returned in ISO 8601 format which includes a calendar date only.
Example: "2021-06-03".
Number Format
All finance data, e.g., price, quantity, fee, etc., should be arbitrary precision numbers and have a string representation.
Example: "10.2000058".
Custom Formats
In nested JSON objects, child objects have custom formats which are described in tables below a place of the first occurrence.
Pagination
Parameters:
| Parameter | Description |
|---|---|
| limit | Number of results per call. |
| offset | Number of results offset. |
| sort | Sort direction. Accepted values: ASC (ascending order), DESC (descending order) |
| by | Filter type. Accepted values: id, timestamp |
| from | Interval initial value. If filter by timestamp is used, then parameter type is DateTime; otherwise — Number. |
| till | Interval end value. If filter by timestamp is used, then parameter type is DateTime; otherwise — Number. |
RATE LIMITS
The maximum number requests per second (RPS) for specific calls can be limited by a rate limit and a burst limit.
The server will process a number of requests that do not exceed the sum of the rate limit and the burst limit within the 1-second sliding window.
If both limits in total are exceeded, an HTTP 429 response is returned.
Requests are being counted per call (REST endpoint or WebSocket message) and:
- per IP address—requests arrived from the same IP address regardless of the identity;
- per account—requests sent under the same identity regardless of an API key, session, connection or IP address.

BEST PRACTICES
The Crosstower 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 a request.
Keep-Alive is a part of the HTTP/1.1 or HTTP/2 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 orders, trades, and any transaction changes.

Authentication
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.
Alternatively, you may obtain API keys via the Auth API by creating a session (POST /account/auth) and an API key (POST /api-key).
Basic
curl -u "apiKey:secretKey" https://api.crosstower.com/api/3/spot/balance
import requests
session = requests.session()
session.auth = ("apiKey", "secretKey")
const fetch = require('node-fetch');
const credentials = Buffer.from('apiKey' + ':' + 'secretKey').toString('base64');
fetch('https://api.crosstower.com/api/3/spot/balance', {
method: 'GET',
headers: {
'Authorization': 'Basic ' + credentials
}
});
To authorize, place credentials to the request header. Those must be constituted of apiKey and secretKey as follows: "Basic " + apiKey + ":" + secretKey.
HS256
from base64 import b64encode
from hashlib import sha256
from hmac import HMAC

self.secret_key = secret_key
self.window = window
def __call__(self, r):
url = urlsplit(r.url)

if url.query:
message.append('?')
message.append(url.query)
if r.body:
message.append(r.body)

data = [self.api_key, signature, timestamp]
if window:
data.append(window)
base64_encoded = b64encode(':'.join(data).encode()).decode()
r.headers['Authorization'] = f'HS256 {base64_encoded}'
return r
auth = HS256(api_key='apiKey', secret_key='secretKey')
with Session() as s:
response = s.get('https://api.crosstower.com/api/3/spot/balance', auth=auth)
print(response.json())
The alternative authentication method is the HMAC signature.
To send a request, you should establish a persistent session using the credentials signed as follows:
- Create an HMAC signature with
secret_keyas the secret key, SHA256 as the hash algorithm, and payload as the message, structured like:<method> + <URL path> + [“?” + <query>] + [<body>] + <timestamp> + [<window>] - Add the authorization header to a request. It should have the following structure:
"HS256 " + Base64(api_key + ":" + <HMAC signature> + ":" + timestamp + [":" + window])

POST /api/3/spot/order
Creates a new spot order.
Requires the "Place/cancel orders" API key Access Right.
Parameters:
| Name | Type | Description |
|---|---|---|
| client_order_id | String | Optional. If omitted, an order will be created, and it will be generated by the Server. Uniqueness must be guaranteed until the last order with the same client_order_id becomes inactive (canceled, expired, or fully executed) and some time after that. Must be from 8 to 32 long. May include Latin letters of any case, digits, and _, -. If specified and corresponds to an existing order, a request will be rejected. |
| symbol | String | Symbol code. |
| side | String | Trade side. Accepted values: sell, buy |
| type | String | Optional. Order type. Must be set to market, stopMarket, or takeProfitMarket if price was left unspecified. Accepted values: limit, market, stopLimit, stopMarket, takeProfitLimit, takeProfitMarket Default value: limit |
| time_in_force | String | Optional. Time in Force instruction. Accepted values: GTC, IOC, FOK, Day, GTD Default value: FOK — type is market, stopMarket, takeProfitMarket; GTC — type is limit, stopLimit, takeProfitLimit. |
| quantity | Number | Order quantity. |
| price | Number | Order price. Required if type is limit, stopLimit, or takeProfitLimit. |
| stop_price | Number | The price level that triggers order activation. Required if type is stopLimit, stopMarket, takeProfitLimit, or takeProfitMarket. |
| expire_time | DateTime | Date of order expiration. Required if time_in_force is GTD. |
| strict_validate | Boolean | Price and quantity will be checked for incrementation within the symbol’s tick size and quantity step. See the symbol's tick_size and quantity_increment. |
| post_only | Boolean | Optional. If a post-only order causes a match with a pre-existing order as a taker, then the order will expire. |
| take_rate | Number | Optional. Liquidity taker fee, a fraction of order volume, such as 0.001 (for 0.1% fee). Can only increase the fee. Used for fee markup. |
| make_rate | Number | Optional. Liquidity provider fee, a fraction of order volume, such as 0.001 (for 0.1% fee). Can only increase the fee. Used for fee markup. |
Response: spot order
Price accuracy and quantity
Symbol config contains the tick_size parameter which means that price should be divided by tick_size with no remainder. quantity should be divided by quantity_increment with no remainder.
By default, if strict_validate is not enabled, the Server rounds half down the price and quantity for tick_size and quantity_increment.
Example of ETHBTC: if tick_size is 0.000001, then price 0.046016 is valid, and 0.0460165 is invalid.
Fees
Charged fee is determined by the symbol's fee_currency. Maker-taker fees offer a transaction rebate make_rate to those who provide liquidity (a maker), while charging customers who take that liquidity take_rate (a taker).
To create buy orders, you must have sufficient balance including fees.
To create market buy orders, you must have sufficient balance including fees, considering maximum possible market order slippage of 10%. Available balance > price × quantity × 1.1 + price × quantity × 1.1 × max(take_rate, make_rate)
Order result status

POST /api/3/spot/order/list
Creates a new spot order list.
Requires the "Place/cancel orders" API key Access Right.
Parameters:
| Name | Type | Description |
|---|---|---|
| order_list_id | String | Order list identifier. If omitted, it will be generated by the system upon order list creation. Must be equal to client_order_id of the first order in the request. |
| contingency_type | String | Order list type. Accepted values: allOrNone (AON) — all orders in the set should be executed within a single transaction or become expired otherwise; oneCancelOther (OCO) — all orders in the set should be canceled if one of them was executed; oneTriggerOther (OTO) — execution of the first (primary) order on the list activates other (secondary) orders as independent of each other; oneTriggerOneCancelOther (OTOCO) — the execution of the first (primary) order on the list activates the other (secondary) orders as an OCO order list. |
| orders | Array of Order | Orders in the list. There must be 2 or 3 orders for allOrNone/oneCancelOther/oneTriggerOther and 3 — for oneTriggerOneCancelOther. Placing any other number of orders will result in an error. |
Order model consists of:
| Name | Type | Description |
|---|---|---|
| client_order_id | String | Optional. Must be different from the identifiers of other orders in the list. If omitted, it will be generated by the system upon order list creation. Uniqueness must be guaranteed until the last order with the same client_order_id becomes inactive (canceled, expired, or fully executed) and some time after that. |
| symbol | String | Symbol code. For an allOrNone order list, symbol code must be unique for each order in the list. For an oneTriggerOneCancelOther order list, symbol code must be the same for all orders in the list (placing orders in different order books is not supported). |
| side | String | Trade side. Accepted values: sell, buy |
| type | String | Optional. Order type. Accepted values: for allOrNone — limit, market; for oneCancelOther (and secondary orders in oneTriggerOneCancelOther) — limit, stopLimit, stopMarket, takeProfitLimit, takeProfitMarket; for oneTriggerOneCancelOther — limit, market, stopLimit, stopMarket, takeProfitLimit, takeProfitMarket. Default value: limit |
| time_in_force | String | Optional (required for allOrNone). Time in Force instruction. Accepted values: for allOrNone — FOK; for oneCancelOther (and secondary orders in oneTriggerOneCancelOther) — GTC, IOC (except limit orders), FOK (except limit orders), Day, GTD; for oneTriggerOneCancelOther — GTC, IOC, FOK, Day, GTD. |
| quantity | Number | Order quantity. |
| price | Number | Order price. Required if type is limit, stopLimit, or takeProfitLimit. |
| stop_price | Number | The price level that triggers order activation. Required if type is stopLimit, stopMarket, takeProfitLimit, or takeProfitMarket. |
| expire_time | DateTime | Date of order expiration. Required if time_in_force is GTD. |
| strict_validate | Boolean | Price and quantity will be checked for incrementation within the symbol’s tick size and quantity step. See the symbol's tick_size and quantity_increment. |
| post_only | Boolean | Optional. If a post-only order causes a match with a pre-existing order as a taker, then the order will expire. |
| take_rate | Number | Optional. Liquidity taker fee, a fraction of order volume, such as 0.001 (for 0.1% fee). Can only increase the fee. Used for fee markup. |
| make_rate | Number | Optional. Liquidity provider fee, a fraction of order volume, such as 0.001 (for 0.1% fee). Can only increase the fee. Used for fee markup. |

Request Object
Request
{
"method": "spot_new_order",
"params": {
"client_order_id": "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, ornullvalue if included. If it is not included it is assumed to be a notification. The value SHOULD NOT benull.
Notification
Notification

"ch": "trades",
"update": {
"BTCUSDT": [{
"t": 1626861123552,
"i": 1555634359,
"p": "30877.68",
"q": "0.00006",
"s": "sell"
}]
}
}
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 an RPC call is made, the server must reply with responses, except for notifications cases.
Response on success subscription is true. Example:
Response
{
"result": true,
"id": 123
}
Response error
{
"error": {
"code": 2001,
"message": "Symbol not found",
"description": "Symbol not found"
},
"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.

In the second case, the first snapshot comes right after the response if the limit parameter is greater than 0. Snapshot gives a full account of the market within the defined scope, and an update contains only recent changes which are being sent immediately.
Batch Notifications
If a market data request includes a number subscriptions, a choice of channel will determine the distribution of updates over incoming notifications.
In the basic scenario, a single notification will contain data on a particular symbol only. Subscription to "batch" channels (ones ending with /batch) allows notifying via combined updates per multiple symbols.

Socket Trading
Trade via socket has some major differences compared to REST:
- quickness. The time to place a new order is a bit higher than network latency;
- the Server notifies you of any order updates;
- FIFO. Your requests are executed on a First In First Out basis.

Socket Wallet 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:
- a subscription to the transactions:
- any sequenced transaction changes such as creating or updating.
- a balance request;
- a transaction history request.
Subscribe to Transactions
Method: subscribe_transactions and the corresponding unsubscription method: unsubscribe_transactions
Income method: transaction_update
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 the transaction polling.
A transaction notification occurs each time the transaction has been changed, such as creating a transaction, updating the pending state (e.g., the hash assigned) or completing a transaction. This is the easiest way to track deposits or develop real-time asset monitoring.

Subscribe to Wallet Balances
Method: subscribe_wallet_balances and the corresponding unsubscription method: unsubscribe_wallet_balances
Income methods: wallet_balances, wallet_balance_update
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 wallet_balance_update event will come with the actual state.
Please be aware that only non-zero values are present.
Event wallet_balances arrives after each successful subscription.
