'symbol' is not recognized

[aalapd]

I am trying to filter currencies by symbol as shown in your documentation:

However, it does not work and returns an error: 'symbols' is not recognized as an internal or external command, operable program or batch file.:

curl -s https://api.frankfurter.dev/v1/1999-01-04?base=USD&symbols=EUR
