Currency Converter API: Live & Historical Exchange Rates

Hosted on ApyHub

What it does

The Currency Converter API returns the exchange rate between two currencies, such as USD to EUR or USD to INR. By default it returns today's rate. Add a date to get the rate for any past day.

Use it for pricing pages, checkout, invoices, and financial reporting. Multiply the returned rate by your amount to convert it. Need several currencies at once? The Multiple Currencies API returns many rates in one call. For the full list of supported currency codes, use the Currencies Dictionary API.

You can start on ApyHub's free tier with no card required.
