API Explorer

You can explore the API using Swagger UI including methods requiring authorization.

DateTime Format

All timestamps are returned in ISO 8601 format or UNIX timestamp in milliseconds (UTC).

Example: "2024-04-03T10:20:49.315Z" or "1614815872000".

Date Format

Some timestamps are returned in ISO 8601 format which includes a calendar date only.

Example: "2024-04-03".

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

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 Sunflower 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.

Request Parameters

Pass a request payload (body) in POST requests and query parameters — in GET requests.

Passing parameters in a way different from the documentation is not supported.

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.

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_key as 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])

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.

`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.
`display_quantity`	String	Optional. The visible part of the hidden order quantity (the only valid value is `"0"`).
`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.

Available balance > price × quantity + price × quantity × max(take_rate, make_rate)

Order result status

For orders with time_in_force equal to IOC or FOK, the REST API returns final order status: filled or expired.

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

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`	[]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 a `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.
`display_quantity`	String	Optional. The visible part of the hidden order quantity (the only valid value is '0').
`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.

POST /api/3/futures/order

Creates a new futures order.

A full order description can be found in the "Margin Order Model" subsection.

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 characters 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	Contract code.
`side`	String	Trade side. Possible values: `sell`, `buy`
`type`	String	Optional. Order type. Possible values: `limit`, `market`, `stopLimit`, `stopMarket`, `takeProfitLimit`, `takeProfitMarket` Default value: `limit`
`time_in_force`	String	Optional. Time in Force instruction. Possible 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`, `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.
`reduce_only`	Boolean	Optional. Reduce-only order, being filled, guarantees not to put the position quantity to the point when the position flips.
`display_quantity`	String	Optional. The visible part of the hidden order quantity (the only valid value is `"0"`).
`margin_mode`	String	Optional. Margin mode. Accepted values: `isolated`, `cross` Default: `isolated`
`close_position`	Boolean	Flag indicating a stop market order must close a margin position when executed or be canceled otherwise. Default: `false` Conditions: `quantity` is omitted.

POST /api/3/futures/order/list

Creates a new futures 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: `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`	[]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. Must be the same for all orders in an `oneTriggerOneCancelOther` order 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 `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. Time in Force instruction. Accepted values: 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.
`reduce_only`	Boolean	Optional. Reduce-only order, being filled, guarantees not to put the position quantity to the point when the position flips.
`display_quantity`	String	Optional. The visible part of the hidden order quantity (the only valid value is '0').
`margin_mode`	String	Optional. Margin mode. Accepted values: `isolated`, `cross` Default: `isolated`
`close_position`	Boolean	Flag indicating a stop market order must close a margin position when executed or be canceled otherwise. Default: `false` Conditions: `quantity` is omitted.

Risk Limits

Risk limits are a set of upper boundaries to the position value regarding the chosen leverage. Thus, each user leverage has its individual limit calculated according to the configuration as follows:

Risk limit = limit_base / ( L ^ limit_power ),

where L is a leverage set by the user.

Note that the resulting limit hedges the value of existing open orders (considering unfilled portion of their quantity) added to the position market value and the value of a new order.

SOCKET API REFERENCE

Connection

The number of WebSoсket connections established per IP address cannot exceed 100.

Ping

wscat -c wss://api.sunflowercorp.com/api/3/ws/public -P

Ping messages

< Received ping
< Received ping
< Received ping

After a WebSocket connection is established, the system sends ping messages to the client each 30 seconds.

In order to see incoming ping messages, place -P flag after the endpoint.

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, or null value if included. If it is not included it is assumed to be a notification. The value SHOULD NOT be null.

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.

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.

Socket Market Data

In order to access market data via WebSocket interface, connect to the endpoint:

wscat -c wss://api.sunflowercorp.com/api/3/ws/public

Request

{
  "method": "subscribe",
  "ch": "orderbook/top/1000ms",          // Channel
  "params": {
    "symbols": [
      "ETHBTC",
      "BTCUSDT"
    ]
  },
  "id": 123
}

From that point on, you will be able to send request messages in JSON format with the following parameters:

Name	Type	Description
`method`	String	The name of the method to be invoked. Accepted values: `subscribe`, `unsubscribe`, `subscriptions`
`ch`	String	Channel name.
`params`	JSON	Parameter values to be used during the method invocation. The set of parameters may vary depending on the channel chosen.
`id`	String	Optional. Request identifier as assigned by sender.

Response

{
  "result": {
    "ch": "orderbook/top/1000ms",        // Channel
    "subscriptions": [
      "ETHBTC",
      "BTCUSDT"
    ]
  },
  "id": 123
}

Any valid and successfully processed request will result in a JSON-formatted response message containing the following fields:

Name	Type	Description
`result`	Result	Details about resulting subscription status.
`id`	String	Optional. Request identifier as assigned by sender.

Result model consists of:

Name	Type	Description
`ch`	String	Channel name.
`subscriptions`	[]String	List of active subscriptions.

Subscriptions

In case of a successful subscriptions, the server will send:

for price/rate/{speed}, ticker/price/{speed}, ticker/{speed}, orderbook/{depth}/{speed}, orderbook/top/{speed}, futures/info: data notifications (data) with a specified rate. {speed} — the period of updating data which embraces the changes that have occurred if any;
for trades, orderbook/full, candles/{period}: snapshot (snapshot) and update (update) notifications.

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 of 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.

`client_order_id`	String	Unique order identifier as assigned by the trader.
`symbol`	String	Symbol code.
`side`	String	Trade side. Accepted values: `sell`, `buy`
`status`	String	Order state. Possible values: `new` — an order is placed in the order book. `suspended` — a `stopLimit`, `stopMarket`, `takeProfitLimit` or `takeProfitMarket` order is parked until it meets the conditions for placement in the order book. `partiallyFilled` — an order is executed, but a part of its quantity is not filled yet. `filled` — (in updates) order quantity filled completely. `canceled` — (in updates) an order is canceled. It can either be done by a user through a cancel/replace request or by the system under specific circumstances. `expired` — (in updates) an order is deactivated after it no longer satisfies Time in Force (IOC, FOK) or Post Only requirements.
`type`	String	Order type. Possible values: `limit`, `market`, `stopLimit`, `stopMarket`, `takeProfitLimit`, `takeProfitMarket`
`time_in_force`	String	Time in Force is a special instruction used when placing an order to indicate how long it will remain active before it is executed or expired. `GTC` — "Good-Till-Canceled" order won't be closed until it is filled. `IOC` — "Immediate-Or-Cancel" order must be executed immediately. Any part of an IOC order that cannot be filled immediately will be canceled. `FOK` — "Fill-Or-Kill" order must be executed immediately and completely or not executed at all. `Day` — keeps the order active until the end of the trading day (23:59 UTC+0). `GTD` — "Good-Till-Date" order may remain active until the time specified in `expire_time`.
`quantity`	Number	Order quantity.
`price`	Number	Order price.
`cum_quantity`	Number	Cumulative executed quantity.
`post_only`	Boolean	A post-only order is an order that does not remove liquidity. If a post-only order causes a match with a pre-existing order as a taker, then the order will expire.

It can either be done by a user through a cancel/replace request or by the system under specific circumstances. `rejected` — (in updates) order request has been rejected (it is applicable exclusively to a request entry, so the `status` of the related canceled/replaced order will not change — i.e., it cannot be different from `new`, `suspended`, `partiallyFilled`). `status` is `rejected`. `expired` — (in updates) an order is deactivated as it no longer satisfies Time in Force (IOC, FOK) or Post Only requirements (`status` is `expired`). `replaced` — (in updates) an order cancel/replace request has been accepted and successfully processed (`status` is `canceled`, a new order placed instead has the `new` status value). `trade` — (in updates) an order has been fully or partially executed (`status` is `filled` or `partiallyFilled`).

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).

`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.
`display_quantity`	String	Optional. The visible part of the hidden order quantity (the only valid value is '0').
`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.

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.

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.

Subscription request:

wscat -c wss://api.sunflowercorp.com/api/3/ws/wallet

{
  "method": "subscribe_transactions",
  "params": {},
  "id": 7652

}

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.
