How to Build a Live FX-Pairs Widget with Python and PHP

If you're working on a finance-related project or fintech application, adding a live FX-pairs widget can be a great way to deliver real-time value to your users. In this post, we'll walk through how to create one using Python (for backend data fetching) and PHP (for simple frontend display).

This kind of setup is especially useful if you're building dashboards, tools for trading de acciones, or just want to enhance your personal finance platform with live currency information — all without relying on heavy third-party widgets.

What You’ll Learn

Fetch live forex quotes (EURUSD, GBPUSD, USDJPY) using Python and a REST API

Save data to JSON and deliver it to your PHP‑based widget

Render an interactive list of FX rates with bid/ask values

Apply simple styling for a clean frontend

Optional enhancements: Chart.js live graphs, flag icons, user‑selectable pairs

Quick Code Walkthrough

Python: Fetch live data and save as JSON

import requests, json

API_KEY = 'YOUR_API_KEY'
pairs = ['EURUSD', 'GBPUSD', 'USDJPY']
url = f"https://marketdata.tradermade.com/api/v1/live?currency_pair={','.join(pairs)}&api_key={API_KEY}"

response = requests.get(url)
data = response.json()['quotes']

with open('fx.json', 'w') as f:
json.dump(data, f)

PHP: Read JSON and render HTML list

$data = json_decode(file_get_contents('fx.json'), true);

echo "

";
foreach ($data as $item) {
echo "
• " . $item['currency_pair'] . ": " . $item['bid'] . " / " . $item['ask'] . "
";
}
echo "

";

CSS: Basic widget styling

ul {
background: #f9f9f9;
padding: 10px;
width: 300px;
border-radius: 8px;
}

li {
margin: 6px 0;
font-size: 14px;
}
