How It Works | MARAAZ

How MARAAZ Currency Converter Works

Transparent, accurate and free. Here is exactly how we source and display exchange rates.

🌐

Live Rate Fetching

Every hour, our system fetches mid-market exchange rates from three independent sources: the European Central Bank (ECB) daily reference rates, the Open Exchange Rates free API, and Frankfurter.app. We prioritize official central bank data.

⚖️

Rate Calculation

We use the mid-market rate — the midpoint between buy and sell rates used by banks and financial institutions. This is the fairest reference rate, the same one used by Google, Reuters and Bloomberg.

🔒

No Markup, No Hidden Fees

We display the pure mid-market rate with no markup added. When you see 1 USD = 0.854 EUR, that is exactly the rate — not inflated to make a profit. We are a free tool, not a money transfer service.

Smart Caching

Rates are cached for 1 hour to ensure fast page loads. If our live data sources are temporarily unavailable, we fall back to our last known rates automatically, so you always see a rate — never an error.

📊

Historical Data

For historical rates, we query the Frankfurter API which serves official ECB data going back to 1999. Cross-rates are calculated via the EUR base to ensure mathematical consistency.

🔄

Auto-Refresh

The converter auto-refreshes rates every 5 minutes if the page stays open, so you always see current data without needing to reload.
