The human decision layer
Human approval infrastructure for AI agents
Let software ask a person, wait safely, and continue with a typed, auditable result.
Ask once. Resume safely.
ActionBox gives agents and production automation a durable way to request approval, collect any missing human input, and resume from a signed response.
Built for real integrations.
Use Source-scoped API keys, typed interactions, webhook delivery, mobile and web inboxes, and an audit trail without building an approval system from scratch.
A clear path from prototype to production.
Start with the free developer tier, connect your first Source, and move to team or high-volume plans when your workflows need more capacity.
