We collect exchange rate data from multiple central banks & commercial sources and then use our own algorithm to blend these different datasets. This process reduces the impact of an incorrect outlying conversion rate supplied by one source. We only support a currency code in ExchangeRate-API if we have at least 3 data sources for that currency.
Our exchange rates are classed as indicative midpoint rates. These are accurate enough for tasks like price estimations in an e-commerce store or stats on a dashboard. In an e-commerce example - our estimation would differ slightly from the final rate a user will actually be charged at when making a payment.
We do not supply buy/sell spread data and so our rates are unsuitable for forex trading or processing cross currency settlements.
You can read more details on our Data information page.
Updated data is available on the hour, every hour for users on paid plans. Our free exchange rate data is updated once every 24 hours. Each currency rate API response served shows a datestamp and the unix time of the most recent data update.
We collect public reference data from a number of central banks and commercial sources around the world. An example would be the reference rates released by the European Central Bank each day.
Each HTTPS GET request you send to our currency converter API endpoints is counted towards the quota your plan allows. You'll receive notification when you've used 75% and then 100% of your quota. You can also see your usage in your dashboard. We softcap at 100% so you'll have a little extra room in the event you reach your plan limit.

What can I say... keep up the good work! The exchange rate API is dead simple and your service has been extremely reliable since day one (really amazing considering it's a free service). We're using it on our ecommerce sites, really helpful for international customers. A+ so far.

We cannot develop our service without ExchangeRate-API. We are metasearch for accommodations and we need to show prices in each currency. It is easy to connect to the API, response speed is fantastic and the price is reasonable. I definitely recommend it.

I use ExchangeRate-API on our Tasmanian Mountain Pepper shop for international customers to get approximate costs. Your free ‘once a day’ update is essential to help make our site look and feel professional.
