This was pretty simple and easy.  Just used requests and a simple class to provide API access.

You'll notice, however, it's not just a list of orders.  There's also this meta part, which has some miscellaneous that I didn't find docs on or uses for.

In each order though, there is a ton of data.  Even data for features Tindie doesn't support yet - like preordering.  Interesting!!! I certainly hope they support that soon.

Anyway, if you are interested in more I highly suggest playing with the API.  There doesn't seem to be much docs on this, but it certainly works.
