API Documentation for Aster Finance

General API Information

  • Some endpoints will require an API Key. Please refer to

  • The base endpoint is:

  • 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.

  • All data types adopt definition in JAVA.

HTTP Return Codes

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

  • HTTP 403 return code is used when the WAF Limit (Web Application Firewall) has been violated.

  • 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 Aster's side.

  • HTTP 503 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 operation; the execution status is UNKNOWN and could have been a success.

Error Codes and Messages

  • Any endpoint can return an ERROR

The error payload is as follows:

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

General Information on Endpoints

  • 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 /fapi/v1/exchangeInfo rateLimits array contains objects related to the exchange's RAW_REQUEST, REQUEST_WEIGHT, and ORDER rate limits. These are further defined in the ENUM definitions section under Rate limiters (rateLimitType).

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

Aster Finance has the right to further tighten the rate limits on users with intent to attack.

IP Limits

  • Every request will contain X-MBX-USED-WEIGHT-(intervalNum)(intervalLetter) in the response headers which has the current used weight for the IP for all request rate limiters defined.

  • 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 received, 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.

  • The limits on the API are based on the IPs, not the API keys.

It is strongly recommended to use websocket stream for getting data as much as possible, which can not only ensure the timeliness of the message, but also reduce the access restriction pressure caused by the request.

Order Rate Limits

  • Every order response will contain a X-MBX-ORDER-COUNT-(intervalNum)(intervalLetter) header which has the current order count for the account for all order rate limiters defined.

  • Rejected/unsuccessful orders are not guaranteed to have X-MBX-ORDER-COUNT-** headers in the response.

  • The order rate limit is counted against each account.

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.

  • Please make sure the signature is the end part of your query string or request body.

  • 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.

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

Filters

Filters define trading rules on a symbol or an exchange.

Symbol filters

PRICE_FILTER

/exchangeInfo format:

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

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

  • minPrice defines the minimum price/stopPrice allowed; disabled on minPrice == 0.

  • maxPrice defines the maximum price/stopPrice allowed; disabled on maxPrice == 0.

  • tickSize defines the intervals that a price/stopPrice 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/stopPrice of the enabled rules:

  • price >= minPrice

  • price <= maxPrice

  • (price-minPrice) % tickSize == 0

LOT_SIZE

/exchangeInfo format:

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

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 allowed.

  • maxQty defines the maximum quantity allowed.

  • 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

MARKET_LOT_SIZE

/exchangeInfo format:

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

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

  • minQty defines the minimum quantity allowed.

  • maxQty defines the maximum quantity allowed.

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

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

  • quantity >= minQty

  • quantity <= maxQty

  • (quantity-minQty) % stepSize == 0

MAX_NUM_ORDERS

/exchangeInfo format:

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

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.

MAX_NUM_ALGO_ORDERS

/exchangeInfo format:

  {
    "filterType": "MAX_NUM_ALGO_ORDERS",
    "limit": 100
  }

The MAX_NUM_ALGO_ORDERS filter defines the maximum number of all kinds of algo orders an account is allowed to have open on a symbol.

The algo orders include STOP, STOP_MARKET, TAKE_PROFIT, TAKE_PROFIT_MARKET, and TRAILING_STOP_MARKET orders.

PERCENT_PRICE

/exchangeInfo format:

  {
    "filterType": "PERCENT_PRICE",
    "multiplierUp": "1.1500",
    "multiplierDown": "0.8500",
    "multiplierDecimal": 4
  }

The PERCENT_PRICE filter defines valid range for a price based on the mark price.

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

  • BUY: price <= markPrice * multiplierUp

  • SELL: price >= markPrice * multiplierDown

MIN_NOTIONAL

/exchangeInfo format:

  {
    "filterType": "MIN_NOTIONAL",
    "notional": "1"
  }

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. Since MARKET orders have no price, the mark price is used.

Websocket Market Streams

  • The baseurl for websocket is wss://fstream.asterdex.com

  • Streams can be access either in a single raw stream or a combined stream

  • Raw streams are accessed at /ws/<streamName>

  • Combined streams are accessed at /stream?streams=<streamName1>/<streamName2>/<streamName3>

  • Combined stream events are wrapped as follows: {"stream":"<streamName>","data":<rawPayload>}

  • All symbols for streams are lowercase

  • A single connection is only valid for 24 hours; expect to be disconnected at the 24 hour mark

  • The websocket server will send a ping frame every 5 minutes. If the websocket server does not receive a pong frame back from the connection within a 15 minute period, the connection will be disconnected. Unsolicited pong frames are allowed.

  • WebSocket connections have a limit of 10 incoming messages per second.

  • A connection that goes beyond the limit will be disconnected; IPs that are repeatedly disconnected may be banned.

  • A single connection can listen to a maximum of 200 streams.

  • Considering the possible data latency from RESTful endpoints during an extremely volatile market, it is highly recommended to get the order status, position, etc from the Websocket user data stream.

Live Subscribing/Unsubscribing to streams

  • The following data can be sent through the websocket instance in order to subscribe/unsubscribe from streams. Examples can be seen below.

  • The id used in the JSON payloads is an unsigned INT used as an identifier to uniquely identify the messages going back and forth.

How to manage a local order book correctly

  1. Open a stream to wss://fstream.asterdex.com/stream?streams=btcusdt@depth.

  2. Buffer the events you receive from the stream. For same price, latest received update covers the previous one.

  3. Drop any event where u is < lastUpdateId in the snapshot.

  4. The first processed event should have U <= lastUpdateId AND u >= lastUpdateId

  5. While listening to the stream, each new event's pu should be equal to the previous event's u, otherwise initialize the process from step 3.

  6. The data in each event is the absolute quantity for a price level.

  7. If the quantity is 0, remove the price level.

  8. Receiving an event that removes a price level that is not in your local order book can happen and is normal.

Account/Trades Endpoints

Considering the possible data latency from RESTful endpoints during an extremely volatile market, it is highly recommended to get the order status, position, etc from the Websocket user data stream.

  • The endpoint should be called repeatedly as heartbeats so that the existing countdown time can be canceled and replaced by a new one.

  • Example usage: Call this endpoint at 30s intervals with an countdownTime of 120000 (120s). If this endpoint is not called within 120 seconds, all your orders of the specified symbol will be automatically canceled. If this endpoint is called with an countdownTime of 0, the countdown timer will be stopped.

  • The system will check all countdowns approximately every 10 milliseconds, so please note that sufficient redundancy should be considered when using this function. We do not recommend setting the countdown time to be too precise or too small.
