time banking, alternative currencies

[Andreas Krueger]

Hey django!

This is slightly off-topic, sorry. My 2nd option isn't, so I try here.

I was asked by a friend how to create a platform where therapists can
exchange goods&services.

My first idea was to plug into an existing time banking / time dollar
/ minuto service, and let them handle the exchange. I am hoping to
find such a system, which has already implemented an API access. Do
you know of any? If not:

My second best option is a django module for time banking /
alternative currency systems.

Thanks!
Andreas

P.S.: With API, I mean something like this:
https://bittrex.com/api/v1.1/public/getmarketsummary?market=btc-drk
https://bittrex.com/Home/Api

And secondly, if there is any end-user texts involved, it should
support German language.

Every idea, hint, url is welcome. Thanks a lot!
