We collect exchange rates from multiple central banks and 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 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.
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 converter API response served shows the epoch time of the most recent data update.
We collect public reference data from a number of central banks around the world. An example would be the reference rates released by the European Central Bank each day.
Each GET request you send to our conversion API endpoints is counted towards the quota your plan allows. You'll receive notification when you've used 75% and 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.
