Curious if there will be a public API for adding cards to a collection?

I have built a robot to sort/id cards. Currently, it just adds to a DB. I would love it if it were able to add directly to deckbox.
Here's a video of the first gen for just card ID only: https://www.youtube.com/watch?v=44O8lgamP5o

My second iteration, in progress actually sorts cards into boxes by user criteria (color, set, value range, whatever).

Considering writing a phone app to scan, as well. Would love to link both to Deckbox.

This would be awesome!

I doubt, however, that a public API would be on the horizon anytime soon. What I'd recommend in the meantime is for your app to have the option to export a Deckbox-compatible CSV file.
