Practical overview

When it fits

Use it when a Java application needs client interfaces for Huobi Spot API requests or WebSocket update subscriptions, and choose public or private clients according to the data required.

Who it is for

  • Java developers building applications or tools that connect to Huobi Spot API services.
  • Teams maintaining an integration based on an earlier SDK version and assessing the documented v3 migration.

Documented uses

  • Request public market data, including candlestick records, through REST.
  • Submit spot trading actions and access private account-related API functions.
  • Subscribe to market, account, and order updates over WebSocket.
Before you choose

Requirements & limits

The repository is public and declares an Apache-2.0 license. The README specifies Java 8. Public Generic and Market clients do not require an API key; private API clients require one.

  • The SDK separates public and private client categories; private functions require an API key.
  • REST is documented for multiple client categories, while WebSocket support is listed for market and account clients; the SDK overview also describes market, account, and order update subscriptions.
  • The README recommends v3 over v1 and v2 and points to migration instructions for existing integrations.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up a Java client for public market data

Create the documented market client and request recent BTC/USDT candlesticks.

Before you start

  • Java 8
  • The SDK source imported into a Java IDE such as IntelliJ IDEA or Eclipse

Steps

  1. Import the SDK source code into a Java IDE.

  2. Create a MarketClient instance using HuobiOptions.

  3. Build a candlestick request for symbol btcusdt, interval MIN1, and size 10.

  4. Call getCandlestick with the request and read the returned candlestick records.

Expected outcome

The example requests and prints recent one-minute BTC/USDT candlestick data through the public market API.

Guide limitations

  • This recipe covers a public market-data request only; private API access requires an API key.
  • The repository example documents the request pattern, not a verified result or compatibility guarantee.
