Currency Localisation

The challenge

Most e-commerce sites default to a single currency — usually USD — regardless of where the visitor is browsing from. A visitor in Australia or Japan sees a price that feels unfamiliar, has to do mental arithmetic, and is more likely to abandon before checkout. Adding a manual currency selector adds friction and most visitors simply ignore it.

What you can achieve

• Prices displayed in the visitor’s local currency on first page load
• No country selector or manual currency toggle needed
• Works on any frontend stack — static sites, React, Vue, or plain HTML
• Covers 150+ countries with accurate primary currency data

How it works

VisitorAPI resolves the visitor’s country from their IP address and returns a currencies array — the first entry is the primary currency for that country. The whole call resolves in ~25ms on average, so the currency is available before the user finishes reading the headline.

1. Call the API on page load with your project ID
2. Read data.currencies[0] — the primary currency code, e.g. "AUD" or "JPY"
3. Update your price display using the returned currency code
