This is Huobi Python SDK, you can import to your python project and use this SDK to query all market data, trading and manage your account.
The SDK supports RESTful API invoking, and concurrently subscribing the market, account and order update from the Websocket connection.
The SDK is compiled by Python 3.7 and above
You can download and open the source code directly in your python project, and then you can follow below steps:
- Create the client instance.
- Call the interfaces provided by client.
# Create generic client instance and get the timestamp
generic_client = GenericClient()
ts = generic_client.get_exchange_timestamp()
print(timestamp)
# Create the market client instance and get the latest btcusdt‘s candlestick
market_client = MarketClient()
list_obj = market_client.get_candlestick("btcusdt", CandlestickInterval.MIN5, 10)
LogInfo.output_list(list_obj)After above section, this SDK should be already download to your local machine, this section introduce this SDK and how to use it correctly.
This is the folder and package structure of SDK source code and the description
- huobi: The core of the SDK
- client: The client that are responsible to access data, this is the external interface layer.
- connection: Responsible to manage the remote server connection
- constant: The constant configuration
- exception: The wrapped exception
- model: The server returned data model
- service: The internal implementation for each client.
- utils:The utility classes, including signature, json parser, logging etc.
- performance: This is for internal performance testing
- tests: This is for internal functional testing
- example: The main package is defined here, it provides the examples how to use client package and response package to access API and read response.
This SDK provides examples that under /example folder, if you want to run the examples to access private data, you need below additional steps:
- Create an API Key first from Huobi official website
- Create privateconfig.py into your huobi folder. The purpose of this file is to prevent submitting SecretKey into repository by accident, so this file is already added in the .gitignore file.
- Assign your API access key and secret key to as below:
p_api_key = "hrf5gdfghe-e74bebd8-2f4a33bc-e7963"
p_secret_key = "fecbaab2-35befe7e-2ea695e8-67e56"If you don't need to access private data, you can ignore the secret key.
Regarding the difference between public data and private data you can find details in Client section below.
In this SDK, the client is the struct to access the Huobi API. In order to isolate the private data with public data, and isolated different kind of data, the client category is designated to match the API category.
All the client is listed in below table. Each client is very small and simple, it is only responsible to operate its related data, you can pick up multiple clients to create your own application based on your business.
| Data Category | Client | Privacy | API Protocol |
|---|---|---|---|
| Generic | GenericClient | Public | Rest |
| Market | MarketClient | Public | Rest, WebSocket |
| Account | AccountClient | Private | Rest, WebSocket v2 |
| Wallet | WalletClient | Private | Rest |
| Order | OrderClient | Private | Rest, WebSocket v2 |
| Margin | MarginClient | Private | Rest |
| ETF | ETFClient | Private | Rest |
There are two types of privacy that is correspondent with privacy of API:
Public client: It invokes public API to get public data (Generic data and Market data), therefore you can create a new instance without applying an API Key.
// Create a GenericClient instance
generic_client = GenericClient()
// Create a MarketClient instance
market_client = MarketClient()Private client: It invokes private API to access private data, you need to follow the API document to apply an API Key first, and pass the API Key to the init function
// Create an AccountClient instance with APIKey
account_client = AccountClient(api_key=g_api_key, secret_key=g_secret_key)
// Create a TradeClient instance with API Key
trade_client = TradeClient(api_key=g_api_key, secret_key=g_secret_key)The API key is used for authentication. If the authentication cannot pass, the invoking of private interface will fail.
There are two protocols of API, Rest and WebSocket
Rest: It invokes Rest API and get once-off response, it has two basic types of method: GET and POST
WebSocket: It establishes WebSocket connection with server and data will be pushed from server actively. There are two types of method for WebSocket client:
- Request method: The method name starts with "Request-", it will receive the once-off data after sending the request.
- Subscription: The method name starts with "Subscribe-", it will receive update after sending the subscription.
In this python SDK, some clients support both Rest and WebSocket protocols, the method name are prefixed and can be easily identified, take TradeClient as an example, the method prefix and their examples are:
- get: get_order, get_matchresult
- post: post_create_order, post_batch_cancel_open_order
- req: req_order_list
- sub: sub_order_update
