Public Rest API for exchange (2019-11-22)

General API Information

  • The base endpoint is: https://altquick.com/
  • All endpoints return either a JSON object or array.
  • Data is returned in descending order. Newest first, oldest last.
  • All time and timestamp related fields are in milliseconds.

HTTP Return Codes

  • HTTP 4XX return codes are used for malformed requests; the issue is on the sender's side.
  • HTTP 429 return code is used when breaking a request rate limit.
  • HTTP 5XX return codes are used for internal errors; the issue is on exchange's side.

Error Codes

  • Any endpoint can return an ERROR

Sample Payload below:

{
  "code": -1104,
  "msg": "Invalid market."
}
  • Specific error codes and messages are defined in Errors Codes.

General Information on Endpoints

  • For GET and POST and DELETE endpoints, parameters must be sent as a query string.
  • Parameters may be sent in any order.

Endpoint security type

  • Each endpoint has a security type that determines the how you will interact with it. This is stated next to the NAME of the endpoint.
    • If no security type is stated, assume the security type is NONE.
  • API-keys are passed into the Rest API via the X-MBX-APIKEY header.
  • API-keys and secret-keys are case sensitive.
  • 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.
  • 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.
  • 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.

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.
  • The logic is as follows: 
    if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow) {
  // process request
} else {
  // reject request
}

It is recommended to use a small recvWindow of 5000 or less! The max cannot go beyond 60,000!

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
market BTC_CLAM
side buy
type limit
quantity 1
price 0.1
recvWindow 5000
timestamp 1499827319559

Example: Query string request

  • queryString: market=BTC_CLAM&side=buy&type=limit&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559

  • HMAC SHA256 signature:

    [linux]$ echo -n "market=BTC_CLAM&side=buy&type=limit&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://altquick.com/api/v1/order?market=BTC_CLAM&side=buy&type=limit&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559&signature=c8db56825ae71d6d79447849e617115f4a920fa2acdcab2b053c4b2838bd6b71'

Filters

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

Market filters

PRICE_FILTER

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

  • minPrice defines the minimum price allowed; disabled on minPrice == 0.
  • maxPrice defines the maximum price allowed; disabled on maxPrice == 0.
  • tickSize defines the intervals that a price can be increased/decreased by; disabled on tickSize == 0.

Any of the above variables can be set to 0, which disables that rule in the price filter. In order to pass the price filter, the following must be true for price of the enabled rules:

  • 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 market. There are 3 parts:

  • minQty defines the minimum quantity allowed.
  • maxQty defines the maximum quantityallowed.
  • stepSize defines the intervals that a quantity can be increased/decreased by.

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

  • quantity >= minQty
  • quantity <= maxQty
  • (quantity-minQty) % stepSize == 0

/exchangeInfo format:

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

MARKET_QUANTITY_INPUT

The MARKET_QUANTITY_INPUT filter defines the symbol used for quantity input when making a market order on the given order side. Any market orders submitted quantity will be assumed to be in the symbol defined in the MARKET_QUANTITY_INPUT filter.

/exchangeInfo format:

{
  "filterType": "MARKET_QUANTITY_INPUT",
  "buy": "quote",
  "sell": "base",
}

MAX_NUM_ORDERS

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

/exchangeInfo format:

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

MIN_ORDER_SIZE

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

/exchangeInfo format:

{
  "filterType": "MIN_NOTIONAL",
  "minNotional": "0.00001000",
}

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",
  "maxNumOrders": 1000
}
