I don't understand what you're complaining about.
All i did was register + $ curl -k -u user:password https://api.no.de/heart -X POST and then i had to generate the ssh key.
Running "curl -k -u user:pass http://api.no.de/heart -X POST" gave no output. I'm noticing in my history that I didn't use https, I guess that's why it didn't work.
Why should I even have to jump to curl to request a coupon?
