2026 French Stock API: Real-Time Quotes, Historical Data & Financials

In 2026, with the rapid advancement of quantitative trading and robo-advisory solutions, European equity markets—particularly France’s Euronext Paris—have become increasingly important data sources. Blue-chip names such as LVMH, L'Oréal, TotalEnergies, and Airbus are not only core constituents of global portfolios but also critical inputs for cross-market arbitrage and multi-factor models. This article provides a detailed guide on accessing French equity data through the iTick API, covering real-time quotes, historical bars, and fundamental financial metrics, complete with production-ready Python integration examples.

I. Why Professional French Equity Data APIs Are Essential

France hosts Europe’s second-largest equity market by capitalization. Its flagship CAC 40 index attracts significant global institutional and systematic capital. However, obtaining clean, low-latency, and comprehensive French market data presents three major challenges:

  • Fragmented data sources — European exchange formats vary widely and require significant normalization effort
  • Latency sensitivity — Most free/public APIs deliver 15-minute delayed data, unacceptable for latency-aware strategies
  • Limited historical depth — Robust backtesting demands long, high-quality historical series that consumer-grade APIs rarely provide

iTick addresses these pain points by offering unified, institutional-grade coverage of Euronext Paris — from real-time Level 1 quotes to deep fundamental datasets.

II. Why iTick Remains the Leading Choice for French Equity Data in 2026

After evaluating major financial data providers, iTick consistently stands out for developers and quant teams focused on European markets.

III. Python Integration Walkthrough: Accessing French Equity Data

The examples below use the requests, websocket-client, pandas and matplotlib libraries.

      pip install requests websocket-client pandas matplotlib

    

Step 1: Obtain API Token

Register at https://itick.org (≈30 seconds, no credit card required). Retrieve your personal API token from the developer dashboard.

Step 2: Real-Time Quote via REST API

Example: retrieving live quote for LVMH (Euronext Paris ticker: MC)

      import requests
from datetime import datetime

# Replace with your actual token
API_TOKEN = "your_api_token_here"
BASE_URL = "https://api.itick.org"

def get_french_stock_quote(symbol: str):
    """
    Fetch real-time quote for a French-listed equity
    :param symbol: local ticker (e.g. "MC" for LVMH)
    """
    url = f"{BASE_URL}/stock/quote"
    params = {
        "region": "FR",
        "code": symbol
    }
    headers = {
        "accept": "application/json",
        "token": API_TOKEN
    }

    try:
        resp = requests.get(url, params=params, headers=headers, timeout=5)
        resp.raise_for_status()
        result = resp.json()

        if result.get("code") == 0:
            data = result["data"]
            print(f"Name:        {data.get('n', 'N/A')}")
            print(f"Symbol:      {data.get('s', 'N/A')}")
            print(f"Last:        {data.get('ld', 'N/A')} EUR")
            print(f"Open:        {data.get('o', 'N/A')} EUR")
            print(f"High:        {data.get('h', 'N/A')} EUR")
            print(f"Low:         {data.get('l', 'N/A')} EUR")
            print(f"Volume:      {data.get('v', 'N/A')} shares")
            print(f"Change %:    {data.get('chp', 'N/A')}%")

            ts = data.get('t', 0) / 1000
            dt = datetime.fromtimestamp(ts)
            print(f"Timestamp:   {dt.strftime('%Y-%m-%d %H:%M:%S')}")
            return data
        else:
            print(f"API Error: {result.get('msg', 'Unknown')}")
            return None

    except Exception as e:
        print(f"Request failed: {e}")
        return None


# Example usage
quote = get_french_stock_quote("MC")

    

Step 3: Historical OHLCV Bars (Backtesting Foundation)

Example: downloading daily bars for TotalEnergies (TTE)

      import requests
import pandas as pd
import matplotlib.pyplot as plt

def get_french_stock_kline(symbol: str, ktype: int = 8, limit: int = 100):
    """
    Fetch historical bars
    ktype: 1=1min, 2=5min, ..., 8=daily, 9=weekly, 10=monthly
    """
    url = f"{BASE_URL}/stock/kline"
    params = {
        "region": "FR",
        "code": symbol,
        "kType": str(ktype),
        "limit": str(limit)
    }
    headers = {"accept": "application/json", "token": API_TOKEN}

    try:
        resp = requests.get(url, params=params, headers=headers)
        result = resp.json()

        if result.get("code") == 0:
            bars = result.get("data", [])
            if not bars:
                print("No data returned")
                return None

            df = pd.DataFrame(bars)
            df['datetime'] = pd.to_datetime(df['t'], unit='ms')
            df.set_index('datetime', inplace=True)

            df.rename(columns={
                'o': 'open', 'h': 'high', 'l': 'low',
                'c': 'close', 'v': 'volume'
            }, inplace=True)

            for col in ['open','high','low','close','volume']:
                df[col] = pd.to_numeric(df[col], errors='coerce')

            print(f"Retrieved {len(df)} bars")
            print(df[['open','high','low','close','volume']].head())

            # Quick visualization
            df['close'].plot(figsize=(12,6), title=f"{symbol} Closing Price")
            plt.grid(True)
            plt.show()

            return df
        else:
            print(f"API Error: {result.get('msg')}")
            return None

    except Exception as e:
        print(f"Exception: {e}")
        return None


# Download last 100 daily bars of TotalEnergies
df_total = get_french_stock_kline("TTE", ktype=8, limit=100)

    

Step 4: Fundamental / Financial Metrics

      def get_french_stock_fundamentals(symbol: str):
    url = f"{BASE_URL}/stock/info"
    params = {"region": "FR", "code": symbol, "type": "stock"}
    headers = {"accept": "application/json", "token": API_TOKEN}

    try:
        resp = requests.get(url, params=params, headers=headers)
        result = resp.json()

        if result.get("code") == 0:
            items = result.get("data", [])
            print(f"Financials for {symbol}")
            for item in items[:3]:   # show most recent 3 periods
                print(f"Market Cap: {item.get('mcb')}")
                print(f"Shares Out: {item.get('tso')}")
                print(f"P/E Ratio:  {item.get('pet')}")
                print("-" * 40)
            return items
        else:
            print(f"API Error: {result.get('msg')}")
            return None

    except Exception as e:
        print(f"Exception: {e}")
        return None


# Example: L'Oréal fundamentals
fundamentals_or = get_french_stock_fundamentals("OR")

    

Step 5: Low-Latency Real-Time Streaming via WebSocket

      import websocket
import json
import threading
import time

WS_URL = "wss://api.itick.org/stock"
API_TOKEN = "your_api_token_here"

def on_message(ws, message):
    data = json.loads(message)
    if "data" in data:
        payload = data["data"]
        symbol = payload.get("s")
        msg_type = payload.get("type")

        if msg_type == "quote":
            print(f"[{symbol}] Last: {payload.get('ld')} EUR | Chg: {payload.get('chp')}%")
        elif msg_type == "depth":
            bids = payload.get("b", [])[:3]
            asks = payload.get("a", [])[:3]
            print(f"[{symbol}] Bid: {bids} | Ask: {asks}")

def on_open(ws):
    print("WebSocket connected")
    sub = {
        "ac": "subscribe",
        "params": "MC$FR,OR$FR",      # LVMH + L'Oréal
        "types": "quote,depth"
    }
    ws.send(json.dumps(sub))
    print(f"Subscribed to: {sub['params']}")

def on_error(ws, error):
    print(f"WS Error: {error}")

def on_close(ws, code, reason):
    print(f"WS Closed: {reason}")

def heartbeat(ws):
    while True:
        time.sleep(30)
        ws.send(json.dumps({
            "ac": "ping",
            "params": str(int(time.time() * 1000))
        }))
        print("Heartbeat sent")

# Initialize & run
ws = websocket.WebSocketApp(
    WS_URL,
    header={"token": API_TOKEN},
    on_open=on_open,
    on_message=on_message,
    on_error=on_error,
    on_close=on_close
)

threading.Thread(target=heartbeat, args=(ws,), daemon=True).start()
ws.run_forever()
