Tips

To reduce bandwidth you can limit the number of output currencies to a specific set of your choice on most API endpoints. To do so, simply append the Fixer API's symbols parameter to your API request and set it to one or more comma-separated currency codes.


curl --request GET 'https://api.apilayer.com/currency_data/live?base=USD&symbols=EUR,GBP' \
--header 'apikey: YOUR API KEY'

It is also possible to convert currencies using historical exchange rate data. To do this, please also use the API's date parameter and set it to your preferred date. (format YYYY-MM-DD)


curl --request GET 'https://api.apilayer.com/currency_data/convert?base=USD&symbols=EUR,GBP,JPY&amount=5&date=2018-01-01' \
--header 'apikey: YOUR API KEY'
