Public Rest API for Binance (2017-12-01)

General API Information

  • The base endpoint is: https://api.binance.com
  • 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 Binance's side.
  • HTTP 504 return code is used when the API successfully sent the message but not get a response within the timeout period. It is important to NOT treat this as a failure; the execution status is UNKNOWN and could have been a success.
  • Any endpoint can retun 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 /api/v1/exchangeInfo rateLimits array contains objects related to the exchange's REQUESTS and ORDER rate limits.
  • A 429 will be returned when either rather 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-MBX-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.
Security Type Description
NONE Endpoint can be accessed freely.
TRADE Endpoint requires sending a valid API-Key and signature.
USER_DATA Endpoint requires sending a valid API-Key and signature.
USER_STREAM Endpoint requires sending a valid API-Key.
MARKET_DATA Endpoint requires sending a valid API-Key.
  • 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 specific the number of milliseconds after timestamp the request is valid for. If recvWindow is not sent, it defaults to 5000.
  • 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.

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

SIGNED Endpoint Examples for POST /api/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.

Key Value
apiKey vmPUZE6mv9SD5VNHk4HlWFsOr6aKE2zvsw0MuIgwCIPy6utIco14y7Ju91duEh8A
secretKey NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j
Parameter Value
symbol LTCBTC
side BUY
type LIMIT
timeInForce GTC
quantity 1
price 0.1
recvWindow 5000
timestamp 1499827319559

Example 1: As a query string

  • queryString: symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559

  • HMAC SHA256 signature:

    [linux]$ echo -n "symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559" | openssl dgst -sha256 -hmac "NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j"
(stdin)= c8db56825ae71d6d79447849e617115f4a920fa2acdcab2b053c4b2838bd6b71

  • curl command:

    (HMAC SHA256)
[linux]$ curl -H "X-MBX-APIKEY: vmPUZE6mv9SD5VNHk4HlWFsOr6aKE2zvsw0MuIgwCIPy6utIco14y7Ju91duEh8A" -X POST 'https://api.binance.com/api/v3/order?symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559&signature=c8db56825ae71d6d79447849e617115f4a920fa2acdcab2b053c4b2838bd6b71'

Example 2: As a request body

  • requestBody: symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559

  • HMAC SHA256 signature:

    [linux]$ echo -n "symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559" | openssl dgst -sha256 -hmac "NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j"
(stdin)= c8db56825ae71d6d79447849e617115f4a920fa2acdcab2b053c4b2838bd6b71

  • curl command:

    (HMAC SHA256)
[linux]$ curl -H "X-MBX-APIKEY: vmPUZE6mv9SD5VNHk4HlWFsOr6aKE2zvsw0MuIgwCIPy6utIco14y7Ju91duEh8A" -X POST 'https://api.binance.com/api/v3/order' -d 'symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=6000000&timestamp=1499827319559&signature=c8db56825ae71d6d79447849e617115f4a920fa2acdcab2b053c4b2838bd6b71'

Example 3: Mixed query string and request body

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

  • requestBody: quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559

  • HMAC SHA256 signature:

    [linux]$ echo -n "symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTCquantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559" | openssl dgst -sha256 -hmac "NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j"
(stdin)= 0fd168b8ddb4876a0358a8d14d0c9f3da0e9b20c5d52b2a00fcf7d1c602f9a77

  • curl command:

    (HMAC SHA256)
[linux]$ curl -H "X-MBX-APIKEY: vmPUZE6mv9SD5VNHk4HlWFsOr6aKE2zvsw0MuIgwCIPy6utIco14y7Ju91duEh8A" -X POST 'https://api.binance.com/api/v3/order?symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC' -d 'quantity=1&price=0.1&recvWindow=6000000&timestamp=1499827319559&signature=0fd168b8ddb4876a0358a8d14d0c9f3da0e9b20c5d52b2a00fcf7d1c602f9a77'

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

Filters

Filters define trading rules on a symbol or an exchange. Filters come in two forms: symbol filters and exchange filters.

Symbol filters

PRICE_FILTER

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

  • minPrice defines the minimum price allowed.
  • maxPrice defines the maximum price allowed.
  • tickSize defines the intervals that a price can be increased/decreased by.

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

  • price >= minPrice
  • price <= maxPrice
  • (price-minPrice) % tickSize == 0

/exchangeInfo 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

/exchangeInfo 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.

/exchangeInfo 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.

/exchangeInfo format:

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

MAX_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.

/exchangeInfo format:

  {
    "filterType": "MAX_ALGO_ORDERS",
    "limit": 5
  }

Exchange Filters

EXCHANGE_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.

/exchangeInfo format:

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

EXCHANGE_MAX_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.

/exchangeInfo format:

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