Do you guys have any plan for releasing new API?
Not yet. Once there will be a plan how to handle API usecases we will let you know on our blog.
whats your usecase, if I may ask?
I’m not the topic starter but I can share mine
I want to create a generative-art store with custom user-created designs. For that I need to be able to upload images via API whenever a customer creates their design. As I get it, at the moment the only way to automate this is to hack in by scraping the upload page UI.
