Is it possible to get ticker of bitcoin.de using an api? I did not found anything in the site. They have an api? It is for my Android App Bitcoin Paranoid.
You could just parse the website. For example to get the current euro and us dollar prices:

curl -s https://www.bitcoin.de/de | sed -n '/EUR/s%.*[^0-9]\([0-9]\+\)\(,\)\([0-9]\+\).*%\1.\3%p'

curl -s https://www.bitcoin.de/de | sed -n '/USD/s%.*[^0-9]\([0-9]\+\)\(,\)\([0-9]\+\).*%\1.\3%p'
