We're working on our public billing API over at BillTo (https://bill.to). Our beta product currently allows you to integrate Stripe to bill customers within seconds, and we'll be opening up the API before Q2 for anyone to automate their billing with our backend.

Would love to chat and see how we can help with your specific use case.

None in the pipeline as of yet... But what's your usecase? I might be inspired enough to start something?
