User Manual

We currently offer spot,future and option on bit.com.

Two methods to call API are currently offered at bit.com: Rest and Websocket.

REST endpoint consists of public and private APIs, where public API can be called directly without authentication.

Private API, on the other hand, requires API key signature authentication, Please register, set up API key and related access set ups on API page before kicking off API development.

Private API access: read,future&option trade,spot trade,wallet,block trade

API types and access details can be viewed API summary.

Websocket API is based on websocket protocol. Users need to first establish websocket connection, then send request for channel subscriptions, bit.com start pushing data (ever after) afterwards. You can always unsubscribe or disconnect if you change mind (no longer wish to be subscribed)

Subscription consists of public and private channels, where public channel can be subscribed directly without authentication. Private channel, on the other hand, requires token and authentication.

Channel types and access details can be viewed channel summary.

API hosts (production)

API hosts (testnet)

API rate limits

In order to ensure the system efficiency, bit.com implements the API rate limits . The public interface implements IP-specified frequency limitation , and the private interface implements user-specified frequency limitation. When a breach happens, a prompt will be returned: “429 too many requests”. The individual API limits can be found on the webpage of the trading center. Users who need to increase the speed limit please contact the support team via [email protected]

Public API: 10 requests per second per IP.
Private API(future&option trade): 5 requests per second per user.
Private API(option trade): 10 requests per second per user.
Private API(Wallet): 1 request per second per user.
Private API(Block Trade):2 requests per second per user.
Private API(Others): 5 requests second per user.

About the type of API rate limits, please refer to API summary.

Unlogged users:100 connections per IP
Unlogged users:10 connection requests per second per IP.
Login users: 5 private connections per user.
Connected IP:disconnection triggers when subscription is not established more than 30s.

Authentication

Private API mandatory fields

If authentication fails, a prompt will be returned: “AkId is invalid” and http status code is 412

  1. Request parameters: JSON Body for POST, query string for the rest
  2. Encode string to sign, for simple json object, sort your parameter keys alphabetically, and join them with '&' like 'param1=value1&param2=value2', then get str_to_sign = api_path + '&' + 'param1=value1&param2=value2'
  3. For nested array objects, encode each object and sort them alphabetically, join them with '&' and embraced with '[', ']', e.g. str_to_sign = api_path + '&' + 'param1=value1&array_key1=[array_item1&array_item2]', see example below.
  4. Signature = hex(hmac_sha256(str_to_sign, secret_key))
  5. Add signature field to request parameter:
    for query string, add '&signature=YOUR_SIGNATURE' for JSON body, add {'signature':YOUR_SIGNATURE}

string to sign

Multi-currency support

Supported currencies: BTC,ETHand BCH

To support multi currency in future versions, we revised the backend architecture. account/order/trade/position/tx_log etc for each currency has its own separate storage space and independent, so the account_id/order_id/trade_id etc for BTC and ETH may have the same values. For example, a user may have an order 123 for BTC, and has an order 123 for ETH as well, i.e. order_id is NOT unique across currencies, but currency + order_id is unique.

Place new order.
For market order, price is not required.
Order type default value is 'limit'.
Time in force default value is 'gtc'.


Enhanced Stop order:
* Order type should be stop-market/stop-limit/trigger-market/trigger-limit.
* stop_price is the target trigger price. price is the order price after triggered
* Support triggered by last-price now.


Auto price type:
usd: When place order, set [auto price type] = "usd", and [auto price] = usd value, order price will be automatically calculated as order_price = auto_price / underlying_price, and order will be automatically requoted every 6s to maintain the usd price

implv: When place order, set [auto price type] = "implv", and [auto price] = implied volatility value, order price will be automatically calculated as order_price = convert_iv_to_usd(auto_price) / underlying_price, , and order will be automatically requoted every 6s to maintain the implied volatility. Example: input 85.56 for 85.56% implied volatility


mmp order:Indicate that this order is mmp-enabled (Market Maker Protection).


bbo order:When bbo is true, auto set limit price (ask0 for buy order, bid0 for sell order), if orderbook is not available, set limit price to mark price. (Batch order not supported)

Users can subscribe to different channels, public and private. Private channel requires token and authentication.

Channels have different specifications, see details in the documentations below.

Users can set the push frequency with the parameter interval.
* interval=raw, the channel will push the updates immediately.
* interval=100ms, the updates within 100ms period will be aggregated and pushed out, note: if no updates within 100ms, no data will be pushed.
* interval=fixed100ms, data will be pushed every 100ms no matter has update or not (Only apply to order_book channel currently).

If the subscription request contains more than one channel and one of them failed, you will receive two separate responses.

Users can stop the feed by submitting an unsubscribe request.

Parameters

Name Type Description
type string [subscribe, unsubscribe]
channels string[] List of channels
currencies string[] List of currencies
categories string[] List of instrument categories
instruments string[] List of instrument IDs

To connect private websocket channels, user needs to first call GET /v1/ws/auth to acquire a token, which will be used to fill in private websocket channel subscription for websocket authentication.

Each token is used for single websocket connection, user needs to acquire new token if reconnect.

For websocket connection, user only need to do authentication in first private channel subscription, subsequent private subscription do not need authenticate.

Parameters

None

Response

Name Type Description
token string private channel authentication token

Heartbeat

协议标准

According to RFC 6455, Websocket protocol uses PING/PONG to indicate connection is alive.

Server sends PING to client every minute through Websocket, client responds with PONG. Connection will be closed if PONG is not received after one minute.

Client can also send PING to check if the server is still responsive.

PING/PONG are both control frames. PING's opcode is 0x9，PONG's opcode is 0xA. One can refer to this link。

自定义PING/PONG消息

由于部分客户端封装实现所限，对控制帧收发不能很好支持。因此在协议标准之外，另外提供一套自定义基于payload的PING/PONG机制。详细参考“Websocket RPC - PING”。

Depth channel can have two message types: snapshot and update. Snapshot sends snapshots of the current order book. Updates sends changes of the order book.

The first message will always be a snapshot followed by updates, if there is any sort of disruption, a new snapshot will be sent follow by updates.

A snapshot includes bids and asks depths, each depth layer consists of two elements: price and quantity.

A normal update message contains sequence and prev_sequence, with the prev_sequence matching the previous update.

Changes in update is a result in a change in depth, every changes consists of three elements: side, price and quantity. Quantity=0 means a layer is been removed from the depth.

Errors

Error Handling

A clarification of bit.com trading APIs:


When calling the trading APIs of bit.com to, e.g. placing, editing, cancelling orders, the caller will get one of the following four types of results:

  1. A response indicating the request was successful
  2. A response indicating the request had been rejected
  3. A response indicating failed to get the processing result of the request
  4. Failed to receive a response (should be handled similarly to type 3, see below)

A result of type 3. happens when the frontend web servers of bit.com failed to receive a response from the matching engine in time (due to a network issue or a timeout). The response can be in the form of

  1. A HTTP response with status "504 - Gateway Timeout", when the failure was at the gateway layer.
  2. A HTTP response with status "200 - OK", but the JSON error code = 18500000 (Rpc timeout)
  3. Other forms of network errors if the failure was even before the gateway of bit.com.

When a result of type 3 happens, it is unknown to the caller whether the sent request has been received/processed/rejected by the matching engine. Therefore, the caller has to make another call checking the state of the order or the account to find out.
