User Manual

We currently offerspot,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,spot trade,future&option 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.

Spot API hosts (production)

Spot API hosts (testnet)

Spot API rate limit

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(spot trade):5 requests per second per user
Private API(Wallet): 1 request 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: 10 private connections per user.
Connected IP:disconnection triggers when subscription is not established more than 30s.

Account mode guidelines

Bit. Com now supports two account types, classic mode and unified margin account mode.
Different modes mainly affect the acquisition of account data and transaction log.
Unified margin trade account abbreviation is UM account.
Unified margin account mode abbreviation is UM mode.

Wallet functions under UM mode

REST trading functions under UM mode

Subscription channel under UM mode

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}

Price logic:
* market order: price must be empty string
* limit order: price must be a valid num string

Quantity logic:
limit order and sell-market order use "qty" field to specific order size, unit is base_currency (like BTC)
buy-market order use "quote_qty" field to specific order size, unit is quote_currency (like USDT), it's actually a target trading amount

* buy-market order: quote_qty must be non-empty, qty must be empty. take BTC-USDT as example, quote_qty should be USDT amount.
* limit order or sell-market order: qty must be non-empty, quote_qty must be empty
* In order query, quote_qty is only valid for buy-market orders
* For buy-market order, order query returns filled_qty in base currency(there is no filled_quote_qty), executed amount is avg_price * filled_qty, the amount maybe less then requested quote_qty as market order is executed in ioc style.

Market order time in force should be ioc

Fee currency:
Fee currency is trade result currency,
if you buy BTC-USDT, fee currency is BTC,
if you sell BTC-USDT, fee currency is USDT,

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
pairs string[] List of currency pairs
interval string [raw, 100ms, fixed100ms] default value is raw
token string Authentication token for private channel

interval parameter:

Response

Name Type Description
code integer 0 means success, !=0 means failure
message string Error message, return when failed
subscription string[] Subscription list, return when successful

    }
}

To connect private websocket channels, user needs to first call GET /spot/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, it's not cached in server, can not be reused, user needs to acquire new token if reconnect. (Thus token of user A can not be reused by user B even when the token is compromised)

For websocket connection, user only need to do authentication in first private channel subscription, subsequent private subscription do not need authenticate(and subsequent token will be discarded, so different users can not share private websocket connections)

Parameters

None

Response

Name Type Description
token string private channel authentication token

Heartbeat

Standard protocol

According to RFC 6455, Websocket protocol uses PING/PONG to indicate that the connection is kept 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。

Custom PING/PONG

Since some clients cannot support sending control frames, payload-based PING/PONG is provided in addition to the standard protocol. Refer to "Websocket RPC - PING" for details.

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.
