moneta

A CL package for querying exchange rates from openexchangerates.org and converting between currencies.

how to make it work

1. clone it on ~/quicklisp/local-projects or wherever your packages live.
2. edit moneta/api-key.lisp adding your api key: (defparameter *exchange-api-id* "lalala")
3. load it with (ql:quickload :moneta)
4. test it with (moneta:convert 1 "BTC" "BRL") or something.

The currency names live, bewilderingly, inside moneta::+currency-names+. They prolly should be keywords instead of strings.
