What Is the WEEX API?

The WEEX API is a set of programmatic interfaces that allows you to interact with the WEEX exchange’s features directly from your own software or scripts. Think of it as a bridge between your trading ideas and the exchange’s infrastructure. By sending HTTP requests or establishing WebSocket connections, you can retrieve real-time market data, manage your account, place trades, and even subscribe to live updates. The API is designed to be accessible yet powerful, catering to both new users who want to experiment and advanced traders building complex systems. According to the WEEX API documentation, it supports a wide range of endpoints for spot trading, market data, account management, and WebSocket streams, all backed by clear examples and error codes to guide you through the process.

What makes the WEEX API stand out is its focus on reliability and ease of use. For instance, endpoints like checking server time or fetching coin pair information are rate-limited at 20 requests per second, ensuring you can pull data quickly without overwhelming the system. The WebSocket streams, as highlighted in WEEX’s blog, are particularly useful for real-time updates, such as monitoring account changes or market movements. As someone who’s explored various exchange APIs, I find WEEX’s documentation intuitive, with practical examples on the right side of their official docs, making it easier to understand request and response structures.

Why Use the WEEX API?

You might be wondering: why should I bother with the WEEX API when I can trade manually on the platform? The answer lies in automation, efficiency, and opportunity. The API empowers you to execute trades faster, analyze markets in real time, and manage your portfolio without constantly monitoring the exchange’s interface. For example, if you’re a day trader, you can use the API to fetch candlestick data and build a script that alerts you when a price pattern forms. If you’re an investor, you can automate rebalancing your portfolio based on market conditions. The WEEX API’s versatility makes it a game-changer for anyone looking to scale their trading strategy.

Another compelling reason to use the WEEX API is the potential to earn through the WEEX affiliate program. By integrating the API into your trading tools or sharing your referral links, you can attract new users to the platform and earn commissions on their trading fees. As WEEX’s blog notes, their affiliate program is designed to reward active users, and combining API-driven strategies with affiliate marketing can amplify your income. Whether you’re coding a trading bot or creating content about your trading journey, the API gives you the tools to maximize both your trading profits and affiliate earnings.

Practical Use Cases for the WEEX API

Let’s dive into some real-world scenarios where the WEEX API can make a difference. Imagine you’re a trader who wants to stay ahead of market trends. You can use the “Get Ticker By Symbol” endpoint to fetch the latest price data for a specific coin pair, such as BTCUSDT. By analyzing the 24-hour high, low, and closing prices, you can build a script that identifies breakout opportunities. For instance, if Bitcoin’s price crosses its 24-hour high, your script could automatically place a buy order using the “New Order” endpoint. This kind of automation saves you time and ensures you don’t miss critical market movements.

Another use case is portfolio monitoring. As an investor, you might hold multiple assets like BTC, USDT, and EOS. The “Get Assets” endpoint lets you retrieve your available, frozen, and locked balances in real time. You could write a Python script that checks your portfolio daily and sends you an email if your USDT balance falls below a certain threshold, prompting you to deposit more funds. This is especially useful for managing risk and staying organized.

For those interested in high-frequency trading, the WebSocket Market Streams are a goldmine. By subscribing to streams like “spot@private.deals.v3.api,” you can receive live updates on your trades, including price, quantity, and fees. This allows you to build a trading bot that reacts instantly to market changes, such as canceling orders if a price moves against your strategy. The WebSocket’s listenKey system, valid for 60 minutes unless kept alive, ensures secure and continuous data flow, as outlined in the WEEX documentation.

Finally, if you’re a content creator or community leader, you can leverage the API to build tools that attract followers to WEEX through your affiliate link. For example, you could create a public dashboard displaying real-time market data using the “Get The Latest Ticker For All Symbols” endpoint. By sharing this tool and embedding your affiliate link, you encourage others to join WEEX, earning you commissions while providing value to your audience.

Step-by-Step Guide to Using the WEEX API

Getting started with the WEEX API is straightforward, even if you’re new to programming. Below, I’ll walk you through the process, from setting up your account to making your first API call and building a simple trading script. Each step is designed to be actionable, with examples drawn from the official documentation to ensure accuracy.

Step 1: Set Up Your WEEX Account and API Key

Before you can use the WEEX API, you need an account on the WEEX exchange. Visit the WEEX website and sign up, ensuring you complete any required identity verification. Once your account is active, navigate to the API management section in your account settings. Here, you can generate an API key and secret, which are essential for authenticating your requests. The WEEX documentation emphasizes including headers like “ACCESS_KEY,” “ACCESS_SIGN,” and “ACCESS_TIMESTAMP” in your requests, so save your key and secret securely. As a tip, never share your API secret, and consider restricting your key’s permissions to specific actions (e.g., read-only for market data) to enhance security.

Step 2: Understand the API Endpoints

The WEEX API is organized into several categories: Spot Market Data, Spot Account, Spot Trade, and WebSocket Streams. Start by exploring the Spot Market Data endpoints, as they’re beginner-friendly and don’t require authentication for public data. For example, the “Check Server Time” endpoint (GET /api/spot/v1/public/time) returns the server’s current timestamp, which is useful for syncing your requests. The response looks like this:

{
  "code": "00000",
  "msg": "success",
  "requestTime": 1622097118135,
  "data": 1622097118134
}

Another great starting point is the “Get All Coin Pairs Information” endpoint (GET /api/spot/v1/public/products), which lists all trading pairs, their minimum and maximum trade amounts, and fee rates. This helps you understand what assets you can trade programmatically. As you progress, explore authenticated endpoints like “Get Assets” or “New Order,” which require your API key and signature.

Step 3: Make Your First API Call

To make your first API call, you’ll need a tool like Postman or a programming language like Python. Let’s use Python with the requests library to fetch all coin pairs. First, install the library by running pip install requests. Then, use the following code:

import requests

url = "https://api.weex.com/api/spot/v1/public/products"
response = requests.get(url)
data = response.json()

if data["code"] == "00000":
    print("Success! Available trading pairs:")
    for pair in data["data"]:
        print(f"{pair['symbolName']}: Min Trade {pair['minTradeAmount']}, Max Trade {pair['maxTradeAmount']}")
else:
    print(f"Error: {data['msg']}")

This script sends a GET request to the coin pairs endpoint and prints each pair’s details. The WEEX API’s rate limit of 20 requests per second ensures you can run this frequently without issues. If you encounter errors like “Invalid ACCESS_KEY” (code 40006), double-check your headers or consult the “Common Error Codes” section in the documentation.

Step 4: Authenticate Requests for Trading

To place trades or check your account, you need to authenticate your requests. This involves creating a signature using your API secret and including it in the request headers. Here’s an example of placing a limit order using the “New Order” endpoint (POST /api/spot/v1/trade/orders):

import requests
import hmac
import hashlib
import time

api_key = "your_api_key"
api_secret = "your_api_secret"
url = "https://api.weex.com/api/spot/v1/trade/orders"
timestamp = str(int(time.time() * 1000))

# Create signature
params = {"symbol": "BTCUSDT_SPBL", "side": "buy", "orderType": "limit", "price": "35000", "quantity": "0.001"}
query_string = "&".join([f"{k}={v}" for k, v in params.items()])
sign_string = f"{timestamp}{query_string}"
signature = hmac.new(api_secret.encode(), sign_string.encode(), hashlib.sha256).hexdigest()

# Send request
headers = {
    "ACCESS_KEY": api_key,
    "ACCESS_SIGN": signature,
    "ACCESS_TIMESTAMP": timestamp,
    "Content-Type": "application/json"
}
response = requests.post(url, json=params, headers=headers)
data = response.json()

print(data)

This script places a buy order for 0.001 BTC at $35,000. The response includes an orderId, which you can use to track the order’s status. Always test with small amounts to avoid costly mistakes, and monitor the “Spot Error Codes” (e.g., 40912 for batch order limits) to troubleshoot issues.

Step 5: Explore WebSocket Streams

For real-time data, set up a WebSocket connection using a library like websocket-client in Python. The WebSocket base URL is wss://wbs.weex.com/ws. First, create a listenKey using the “Create a ListenKey” endpoint (POST /api/v3/userDataStream). Then, subscribe to streams like “spot@private.account.v3.api” to monitor account updates. Here’s a sample:

import websocket
import json

listen_key = "your_listen_key"
ws_url = f"wss://wbs.weex.com/ws?listenKey={listen_key}"

def on_message(ws, message):
    data = json.loads(message)
    print(f"Account Update: {data}")

def on_open(ws):
    subscription = {
        "method": "SUBSCRIPTION",
        "params": ["spot@private.account.v3.api"]
    }
    ws.send(json.dumps(subscription))

ws = websocket.WebSocketApp(ws_url, on_message=on_message, on_open=on_open)
ws.run_forever()

This script prints account balance changes in real time. Keep your listenKey alive by sending a PUT request every 30 minutes, as recommended in the documentation.

Step 6: Leverage the Affiliate Program

To boost your earnings, join the WEEX affiliate program. After signing up, you’ll receive a unique referral link. Share this link alongside tools or content you create with the API. For example, you could build a Telegram bot that shares market updates using the “Get Ticker By Symbol” endpoint and includes your affiliate link in the bot’s messages. As new users sign up and trade, you earn commissions. WEEX’s blog highlights how affiliates can benefit from the platform’s growing user base, making this a smart way to monetize your API projects.

Tips for Success with the WEEX API

As you dive deeper, keep a few best practices in mind. Always test your scripts in a sandbox environment or with small trades to avoid errors. Monitor rate limits to prevent “Request is too frequent” errors (HTTP 429). Regularly check the WEEX API documentation for updates, as it’s continuously improved. If you hit roadblocks, the “Common Error Codes” and “Spot Error Codes” sections are lifesavers. Finally, engage with the WEEX community or support team for help—their blog and GitHub repository (WEEX API docs) are excellent resources.
