Using fixerapi

To access a tibble with the name and currency symbol (a three letter code) for all currencies available through the API, use fixer_symbols().

There are five currency exchange query types, which calls endpoints. They are:

With the exception of fixer_convert(), which is limited to two currencies, all functions give an option for a base currency that is indexed to 1 and other currencies are compared to – the default is the Euro – and to limit the currencies it is compared with, using the symbols parameter, which takes a character vector of currency symbols. If no symbols are specified, all available currencies are returned.

today_symbols <- fixer_latest(base = "EUR", 
                              symbols = c("JPY", "GBP", "USD", "CAD", "CHF"))


#> A tibble: 5 x 2
#>   name    value
#>   <chr>   <dbl>
#> 1 JPY   131.   
#> 2 GBP     0.873
#> 3 USD     1.23 
#> 4 CAD     1.57 
#> 5 CHF     1.18
