The API is ready now. Wasn’t easy but @daniel got it to work on the live site today (yay!). I’ll move the documentation with some updates to our API manual now.
How much of the user interface designed by Natalia’s team would these onboarding sites re-use? If they will look and behave quite differently, you can also make your own brief and look for somebody to create the JavaScript application for this. It will still make sense that the same person is then briefed by @hugi later and does the Biennale site as well. But it could speed things up somewhat. I can add the relevant technical parts to that brief, if you decide to go this way.
