NAME

Finance::Currency::Convert::WebserviceX - Lightweight currency conversion using WebserviceX.NET

CONTENTS

SYNOPSIS



    use Finance::Currency::Convert::WebserviceX;
    my $cc = Finance::Currency::Convert::WebserviceX->new;
    my $result = $cc->convert(1.95, USD, JPY);



DESCRIPTION

This is a lightweight module to do currency conversion using the Currency Converter web service at http://www.webservicex.net/.

The motivation for this module was many fold. First, Finance::Currency::Convert with Finance::Quote was a little too bulky for my needs, esp the need to download or maintain conversion tables. Finance::Currency::Convert::Yahoo seemed to be based on screen scraping. Way to fragile for my taste. Finance::Currency::Convert::XE has usage restrictions from XE.com. [No offense intended to any of the authors above]

CONSTRUCTOR

You know the routine. new is your friend.



    use Finance::Currency::Convert::WebserviceX;
    my $cc = Finance::Currency::Convert::WebserviceX->new;



METHODS

convert($value, CW$from, CW$to)

Converts a number value from one currency to another and returns the result.



    my $result = $cc->convert(1.95, USD, JPY);



If an error occurs, no value is given, or the from/to aren’t 3 letter currency codes, convert returns undef.

For now, you can access the request response after calling C>convert>:



    my $response = $self->{response};



This returns a HTTP::Response object that can be used to inspect any remote web service errors. $self->response{’request’} is reset at the beginning of every call to convert and returns undef otherwise.
value The number or price to be converted.
from The three letter ISO currency code for the currency amount specified in value. See Locale::Currency for the available currency codes.
to The three letter ISO currency code for the currency you want the value to be converted to. See Locale::Currency for the available currency codes.

    cache

Gets the reference to the cache hash.
