Build on the Threadbox REST API

The widget covers most teams, but some need the agent inside their own product, mobile app or internal tool. The REST API exposes everything the widget does.

Stream replies token by token, receive tool-call events as actions run, manage knowledge sources programmatically and react to conversations, leads and escalations through signed webhooks.
