Ethereum API: Getting Latest Trade Prices, Bids, and Asks on Huobi.com

As a cryptocurrency investor or enthusiast, having access to real-time data is crucial for making informed trading decisions. Huobi.com, one of the largest and most reputable cryptocurrency exchanges, provides an API (Application Programming Interface) that allows developers to retrieve various market data feeds. In this article, we’ll explore how to use the Huobi.com API to get the latest trade prices, bids, and asks.

Prerequisites

Before you start, make sure you have:

• An account on Huobi.com.

• A registered developer account (not necessary for public APIs).

• Familiarity with the Python programming language or your preferred API client library.

API Overview

Huobi.com’s API provides access to various data feeds, including market data, order books, and other relevant information. The main endpoints we’ll focus on are:

• GET /api/v5/market/price

• GET /api/v5/market/bids

• GET /api/v5/market/asks

Step-by-Step Instructions

1. Register an Application on Huobi.com

Go to the [Huobi.com Developer Portal]( and register as a developer. You’ll need to provide your email address, username, and password.

2. Obtain Your API Key

After registering, navigate to the [API Keys page]( and create an account or log in if you already have one. This will generate your API key.

3. Choose Your Endpoint

Select the endpoint that suits your needs:

• GET /api/v5/market/price for last trading price.

• GET /api/v5/market/bids and GET /api/v5/market/asks for order book data (bids and asks).

4. Set the API Request Options

Use the following request options to customize your API call:

• method: GET

• params: price, bids, or asks

• headers: Define any additional headers required by the API.

Example: GET /api/v5/market/price?symbol=eth&limit=10

5. Send the Request

Use your preferred API client library (e.g., Python’s requests module) to send a GET request to the specified endpoint and API key.

Python Example

import requests


def get_huobi_api_data(api_key, symbol):

    headers = {'Authorization': f'Bearer {api_key}'}

    params = {

        'symbol': symbol,

        'limit': 10

    }

    

    response = requests.get(f' params=params, headers=headers)

    

    if response.status_code == 200:

        data = response.json()

        return data['data']

    else:

        print(f'Error: {response.status_code}')

        return None


api_key = 'your_api_key_here'

symbol = 'eth'


data = get_huobi_api_data(api_key, symbol)

print(data)

6. Parse and Process the Data

Once you receive the data, parse it according to your needs. For example:

• Convert the last trading price from seconds since epoch to USD.

• Extract bids and asks for a given pair.

Bids and Asks Data

To access bids and asks, use the same endpoint but replace price with bids or asks. You can also filter by symbol using the API key and parameter.

Example:

“`python

def get_huobi_bids_api_data(api_key, symbol):

headers = {‘Authorization’: f’Bearer {api_key}’}

params = {

‘symbol’: symbol,

‘limit’: 10

}

response = requests.get(f’ params=params, headers=headers)

if response.status_code == 200:

data = response.json()

return data[‘data’]

else:

print(f’Error: {response.
