@continue.dev I recently followed the Discord Invite, but (even after going through the initial 4-step flow) I am not able to post anywhere. Any way to fix this?

@obsidian.md I would like to update my vault with documents, which I create via python scripts. Does obisidan sync have something like a public API, where I can remotely manage the content of my vault? (without being bound to do it on a specific computer - which works today via iCloud as well).
