Typebot currently offers 2 APIs: Builder and Chat
The Builder API is about what you can edit on https://app.typebot.io (i.e. create typebots, insert blocks etc, get results...). It is currently under active development and new endpoints will be added incrementally.
You should not use it in production. This API is experimental at the moment and will be heavily modified with time.
The Chat API allows you to execute (chat) with a typebot.
