The FlowRepository admin email (flowrepository-admin@isac-net.org) has not been working since December 13th 2018 and is still not working. From January 3rd 2019 the website will now link directly to the admin, Justin, through his email of justinmeskas@gmail.com. If you had sent a support ticket or any other means to connect to the admins of FlowRepository between those two dates, those emails did not go through. Please forward any emails to him, or re-create any issues through the website. Sorry for any inconvenience and thank you for your patience and understanding.

Is there an interface (API) that I could use to talk to FlowRepository programatically?

Yes, there is. It is currently possible to use it to get read only access to public data, and we continue to development and extend it. Please see our Resources for Developers for further details, and please let us know that you will be using it so that we can help.
