Understand the framework. Find the right boundary. Build the next conversation.
Conceptual guides and illustrative examples. Stable API and SDK references will follow as they are published.

Quickstart
Understand the 4VF building blocks and assemble a first voice agent configuration.
Read the quickstart
Start by describing one conversation and its intended outcome. Choose the information your agent needs, the actions it may take and the point at which it should bring in a person.
Shape the agent. Write a system prompt, an opening message and clear boundaries.
Connect context and actions. Define knowledge sources and scoped tool inputs.
Trace the path. Model conditions, the voice response and a human handoff. Test the experience before connecting a channel.
This is a conceptual quickstart. Public account registration is not yet open.
Visual routing, conditions, actions, branching and handoff concepts.
Read the guide
A workflow makes the next action explicit. Begin with a trigger, interpret input, then use conditions to route toward knowledge, a tool, a response or a person.
The public canvas lets you inspect a sample flow and download its example configuration. It does not publish or execute a production workflow.
Event-driven integration concepts and payload-handling guidance.
Read the guide
Design your receiving application around explicit event types and structured payloads. Consider validation, duplicate events and how your application records processing outcomes.
Delivery behavior and verification mechanisms depend on the published production contract. The current developer example illustrates handling only.
Illustrative implementation patterns clearly separated from final API guarantees.
Read the guide
Explore an appointment assistant: identify the caller’s preferred day, request availability through a calendar tool, confirm the choice and return a voice response.
Keep sample data separate from production records. The site’s interactive examples run locally and do not access a microphone, place calls or execute external tools.
Architecture-focused guidance for common voice system patterns.
Read the guide
Begin an architecture review with transport, intelligence and execution boundaries. Identify which system owns the data and which component can change it.
Follow one conversation end to end: input, context, decision, action, response and observability. Make failure and human handoff paths explicit.
