Bot Integration with HTX (Huobi) API

MEXC API Bot Integration

MEXC — an exchange with one of the widest listings of altcoins. REST API v3 is modeled after Binance API — those who have worked with Binance will figure it out quickly. Key feature: MEXC often lists tokens before other exchanges, creating opportunities for listing sniper bots.

Connection via CCXT

import ccxt
import asyncio

exchange = ccxt.mexc({
    'apiKey': API_KEY,
    'secret': API_SECRET,
    'enableRateLimit': True,
})

async def get_balance():
    balance = await exchange.fetch_balance()
    return {k: v for k, v in balance['total'].items() if v > 0}

async def place_order(symbol: str, side: str, amount: float, price: float = None):
    order_type = 'market' if price is None else 'limit'
    return await exchange.create_order(symbol, order_type, side, amount, price)

MEXC REST API Directly

For specific functions, use MEXC direct API:

import hmac, hashlib, time, requests

class MEXCClient:
    BASE_URL = 'https://api.mexc.com'
    
    def __init__(self, api_key: str, secret: str):
        self.api_key = api_key
        self.secret = secret
    
    def _sign(self, params: dict) -> str:
        query = '&'.join(f"{k}={v}" for k, v in sorted(params.items()))
        return hmac.new(self.secret.encode(), query.encode(), hashlib.sha256).hexdigest()
    
    def get_ticker(self, symbol: str) -> dict:
        r = requests.get(f"{self.BASE_URL}/api/v3/ticker/bookTicker", 
                         params={'symbol': symbol})
        return r.json()
    
    def place_order(self, symbol: str, side: str, order_type: str, 
                     quantity: float, price: float = None) -> dict:
        params = {
            'symbol': symbol,
            'side': side.upper(),
            'type': order_type.upper(),
            'quantity': quantity,
            'timestamp': int(time.time() * 1000),
        }
        if price:
            params['price'] = price
        
        params['signature'] = self._sign(params)
        
        r = requests.post(f"{self.BASE_URL}/api/v3/order",
                          headers={'X-MEXC-APIKEY': self.api_key},
                          params=params)
        return r.json()

Listing Sniper Strategy

MEXC often announces listings in advance. The bot monitors announcements and prepares to buy in the first second:

class ListingSniper:
    async def monitor_new_listings(self):
        """Check for new pairs every 30 seconds"""
        known_symbols = set(await self.get_all_symbols())
        
        while True:
            current_symbols = set(await self.get_all_symbols())
            new_symbols = current_symbols - known_symbols
            
            for symbol in new_symbols:
                print(f"New listing detected: {symbol}")
                await self.prepare_buy_order(symbol)
            
            known_symbols = current_symbols
            await asyncio.sleep(30)
    
    async def prepare_buy_order(self, symbol: str):
        """Quick buy when new listing detected"""
        try:
            order = await self.exchange.create_order(
                symbol, 'market', 'buy', 
                self.buy_amount_usdt,
                params={'quoteOrderQty': self.buy_amount_usdt}  # buy for X USDT
            )
            print(f"Bought {symbol}: {order}")
        except Exception as e:
            print(f"Failed to buy {symbol}: {e}")

Rate Limits

MEXC limits: 500 requests per second for API, 20 per second for trading operations. When exceeded — 429 response with Retry-After header.

# CCXT built-in rate limiter
exchange.enableRateLimit = True
exchange.rateLimit = 50  # ms between requests

MEXC bot integration: 1–2 weeks. MEXC is compatible with most Binance API code — migration usually takes 1–2 days.
