About Zatanna
Summary
Zatanna converts software portal workflows into stable, callable APIs for AI agents. By observing the real network traffic behind a portal, it reconstructs the underlying request flow, auth, and session handling, then exposes a single clean endpoint. It replaces fragile browser automation and headless-Chrome bots that teams would otherwise build and babysit to let agents interact with software that has no public API.
