DEPENDENCIES HTTP::Request LWP::UserAgent MIME::Base64 Digest::SHA EXAMPLES get current XLTC market price in EUR use Finance::Bank::Kraken; use JSON; my $kraken = new Finance::Bank::Kraken; my $res = $kraken->call(Public, 'Ticker', ['pair=XLTCZEUR,XXBTZEUR']); printf "1 XLTC is %f EUR\n", from_json($res)->{'result'}->{'XLTCZEUR'}->{'c'}[0] unless $res =~ /^5/; get XLTC account balance use Finance::Bank::Kraken; use JSON; my $kraken = new Finance::Bank::Kraken; $kraken->key("mysupersecretkey"); $kraken->secret("mysupersecretsecret"); my $res = $kraken->call(Private, 'Balance'); printf "balance: %f XLTC\n", from_json($res)->{'result'}->{'XLTC'} unless $res =~ /^5/; Q&A Why does "call" return a 404? Probably you misspelled the method. Please check the API documentation and keep in mind the methods are case sensitive. Why does "call" return a 500? Maybe there's a problem with the ssl chain of trust. Either install Mozilla::CA or set (one of) the following environment variables "PERL_LWP_SSL_CA_FILE", "HTTPS_CA_FILE", "PERL_LWP_SSL_CA_PATH", "HTTPS_CA_DIR". See LWP::UserAgent for details.
