Public Rest API (2018-09-25)

General API Information

  • All endpoints return either a JSON object or array.

  • Data is returned in ascending order. Oldest first, newest last.

  • All time and timestamp related fields are in milliseconds.

  • HTTP 4XX return codes are used for for malformed requests; the issue is on the sender's side.

  • HTTP 429 return code is used when breaking a request rate limit.

  • HTTP 418 return code is used when an IP has been auto-banned for continuing to send requests after receiving 429 codes.

  • HTTP 5XX return codes are used for internal errors; the issue is on exchange's side. It is important to NOT treat this as a failure operation; the execution status is UNKNOWN and could have been a success.

  • Any endpoint can return an ERROR; the error payload is as follows:

{
  "code": -1121,
  "msg": "Invalid symbol."
}

  • Specific error codes and messages defined in another document.

  • For GET endpoints, parameters must be sent as a query string.

  • For POST, PUT, and DELETE endpoints, the parameters may be sent as a query string or in the request body with content type application/x-www-form-urlencoded. You may mix parameters between both the query string and request body if you wish to do so.

  • Parameters may be sent in any order.

  • If a parameter sent in both the query string and request body, the query string parameter will be used.

LIMITS

  • The /openapi/v1/exchange rateLimits array contains objects related to the exchange's REQUEST_WEIGHT and ORDER rate limits.

  • A 429 will be returned when either rate limit is violated.

  • Each route has a weight which determines for the number of requests each endpoint counts for. Heavier endpoints and endpoints that do operations on multiple symbols will have a heavier weight.

  • When a 429 is recieved, it's your obligation as an API to back off and not spam the API.

  • Repeatedly violating rate limits and/or failing to back off after receiving 429s will result in an automated IP ban (http status 418).

  • IP bans are tracked and scale in duration for repeat offenders, from 2 minutes to 3 days.

Endpoint security type

  • Each endpoint has a security type that determines the how you will interact with it.

  • API-keys are passed into the Rest API via the X-BH-APIKEY header.

  • API-keys and secret-keys are case sensitive.

  • API-keys can be configured to only access certain types of secure endpoints. For example, one API-key could be used for TRADE only, while another API-key can access everything except for TRADE routes.

  • By default, API-keys can access all secure routes.

  • TRADE and USER_DATA endpoints are SIGNED endpoints.

SIGNED (TRADE and USER_DATA) Endpoint security

  • SIGNED endpoints require an additional parameter, signature, to be sent in the query string or request body.

  • Endpoints use HMAC SHA256 signatures. The HMAC SHA256 signature is a keyed HMAC SHA256 operation. Use your secretKey as the key and totalParams as the value for the HMAC operation.

  • The signature is not case sensitive.

  • totalParams is defined as the query string concatenated with the request body.

Timing security

  • A SIGNED endpoint also requires a parameter, timestamp, to be sent which should be the millisecond timestamp of when the request was created and sent.

  • An additional parameter, recvWindow, may be sent to specify the number of milliseconds after timestamp the request is valid for. If recvWindow is not sent, it defaults to 5000.

  • Currently, recvWindow is only used when creates order.

  • The logic is as follows:

    if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow) {
  // process request
} else {
  // reject request
}

Serious trading is about timing. Networks can be unstable and unreliable, which can lead to requests taking varying amounts of time to reach the servers. With recvWindow, you can specify that the request must be processed within a certain number of milliseconds or be rejected by the server.

It recommended to use a small recvWindow of 5000 or less!

SIGNED Endpoint Examples for POST /openapi/v1/order

Here is a step-by-step example of how to send a vaild signed payload from the Linux command line using echo, openssl, and curl.

Example 1: As a query string

  • queryString: symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000

  • HMAC SHA256 signature:

[linux]$ echo -n "symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000" | openssl dgst -sha256 -hmac "lH3ELTNiFxCQTmi9pPcWWikhsjO04Yoqw3euoHUuOLC3GYBW64ZqzQsiOEHXQS76"
(stdin)= 5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6

  • curl command:

(HMAC SHA256)
[linux]$ curl -H "X-BH-APIKEY: tAQfOrPIZAhym0qHISRt8EFvxPemdBm5j5WMlkm3Ke9aFp0EGWC2CGM8GHV4kCYW" -X POST 'https://$HOST/openapi/v1/order?symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000&signature=5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6'

Example 2: As a request body

  • requestBody: symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000

  • HMAC SHA256 signature:

[linux]$ echo -n "symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000" | openssl dgst -sha256 -hmac "lH3ELTNiFxCQTmi9pPcWWikhsjO04Yoqw3euoHUuOLC3GYBW64ZqzQsiOEHXQS76"
(stdin)= 5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6

  • curl command:

(HMAC SHA256)
[linux]$ curl -H "X-BH-APIKEY: tAQfOrPIZAhym0qHISRt8EFvxPemdBm5j5WMlkm3Ke9aFp0EGWC2CGM8GHV4kCYW" -X POST 'https://$HOST/openapi/v1/order' -d 'symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000&signature=5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6'

Example 3: Mixed query string and request body

  • queryString: symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC

  • requestBody: quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000

  • HMAC SHA256 signature:

[linux]$ echo -n "symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTCquantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000" | openssl dgst -sha256 -hmac "lH3ELTNiFxCQTmi9pPcWWikhsjO04Yoqw3euoHUuOLC3GYBW64ZqzQsiOEHXQS76"
(stdin)= 885c9e3dd89ccd13408b25e6d54c2330703759d7494bea6dd5a3d1fd16ba3afa

  • curl command:

(HMAC SHA256)
[linux]$ curl -H "X-BH-APIKEY: tAQfOrPIZAhym0qHISRt8EFvxPemdBm5j5WMlkm3Ke9aFp0EGWC2CGM8GHV4kCYW" -X POST 'https://$HOST/openapi/v1/order?symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC' -d 'quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000&signature=885c9e3dd89ccd13408b25e6d54c2330703759d7494bea6dd5a3d1fd16ba3afa'

Note that the signature is different in example 3. There is no & between "GTC" and "quantity=1".

Internal Account Transfer (ACCOUNT_TRANSFER)

POST /openapi/v1/transfer

Internal transfer

Weight: 1

Parameters:

Response:

{
    "success":"true" // success
}

Explanation

  1. Either transferring or receiving account must be the main account (Token trading account)

  2. Main account api can support transferring to other account(including sub-accounts) and receiving from other accounts

  3. Sub-account API only supports transferring from current account to the main-account. Therefore fromAccountType\fromAccountIndex\toAccountType\toAccountIndex should be left empty.

        "created": "1578640809195"
    }
]

Explanation

  1. Main-account API can query balance flow for token account and other accounts(including sub-accounts, or designated accountType and accountIndex accounts)

  2. Sub-account API can only query current sub-account, therefore accountType and accountIndex is not required.

Please see the following for balance flow types

Filters

Filters define trading rules on a symbol. Filters come in two forms: symbol filters and broker filters.

Symbol filters

PRICE_FILTER

The PRICE_FILTER defines the price rules for a symbol. There are 3 parts:

  • minPrice defines the minimum price/stopPrice allowed.

  • maxPrice defines the maximum price/stopPrice allowed.

  • tickSize defines the intervals that a price/stopPrice can be increased/decreased by.

In order to pass the price filter, the following must be true for price/stopPrice:

  • price >= minPrice

  • price <= maxPrice

  • (price-minPrice) % tickSize == 0

/exchange format:

  {
    "filterType": "PRICE_FILTER",
    "minPrice": "0.00000100",
    "maxPrice": "100000.00000000",
    "tickSize": "0.00000100"
  }

LOT_SIZE

The LOT_SIZE filter defines the quantity (aka "lots" in auction terms) rules for a symbol. There are 3 parts:

  • minQty defines the minimum quantity/icebergQty allowed.

  • maxQty defines the maximum quantity/icebergQty allowed.

  • stepSize defines the intervals that a quantity/icebergQty can be increased/decreased by.

In order to pass the lot size, the following must be true for quantity/icebergQty:

  • quantity >= minQty

  • quantity <= maxQty

  • (quantity-minQty) % stepSize == 0

/exchange format:

  {
    "filterType": "LOT_SIZE",
    "minQty": "0.00100000",
    "maxQty": "100000.00000000",
    "stepSize": "0.00100000"
  }

MIN_NOTIONAL

The MIN_NOTIONAL filter defines the minimum notional value allowed for an order on a symbol. An order's notional value is the price * quantity.

/exchange format:

  {
    "filterType": "MIN_NOTIONAL",
    "minNotional": "0.00100000"
  }

MAX_NUM_ORDERS

The MAX_NUM_ORDERS filter defines the maximum number of orders an account is allowed to have open on a symbol. Note that both "algo" orders and normal orders are counted for this filter.

/exchange format:

  {
    "filterType": "MAX_NUM_ORDERS",
    "limit": 25
  }

MAX_NUM_ALGO_ORDERS

The MAX_ALGO_ORDERS filter defines the maximum number of "algo" orders an account is allowed to have open on a symbol. "Algo" orders are STOP_LOSS, STOP_LOSS_LIMIT, TAKE_PROFIT, and TAKE_PROFIT_LIMIT orders.

/exchange format:

  {
    "filterType": "MAX_NUM_ALGO_ORDERS",
    "maxNumAlgoOrders": 5
  }

ICEBERG_PARTS

The ICEBERG_PARTS filter defines the maximum parts an iceberg order can have. The number of ICEBERG_PARTS is defined as CEIL(qty / icebergQty).

/exchange format:

  {
    "filterType": "ICEBERG_PARTS",
    "limit": 10
  }

Broker Filters

BROKER_MAX_NUM_ORDERS

The MAX_NUM_ORDERS filter defines the maximum number of orders an account is allowed to have open on the exchange. Note that both "algo" orders and normal orders are counted for this filter.

/exchange format:

  {
    "filterType": "BROKER_MAX_NUM_ORDERS",
    "limit": 1000
  }

BROKER_MAX_NUM_ALGO_ORDERS

The MAX_ALGO_ORDERS filter defines the maximum number of "algo" orders an account is allowed to have open on the exchange. "Algo" orders are STOP_LOSS, STOP_LOSS_LIMIT, TAKE_PROFIT, and TAKE_PROFIT_LIMIT orders.

/exchange format:

  {
    "filterType": "BROKER_MAX_NUM_ALGO_ORDERS",
    "limit": 200
  }
