Andon — Trust Gate for AI Agents – Deterministic pre-execution control for AI actions and payments

Summary: Andon is a pre-execution trust gate that evaluates AI agent actions such as API calls, URL access, and payments, returning Approve, Block, or Human Review decisions within ~200ms. It provides a deterministic rules engine with an auditable evidence chain to ensure traceability and risk management before execution.

What it does

Andon intercepts AI agent actions before execution, applying deterministic rules to approve, block, or flag them for human review. Each decision includes verifiable evidence without exposing source or output data.

Who it's for

It is designed for workflows involving agentic payments, procurement, tool use, and operations automation where preventing errors before execution is critical.

Why it matters

Andon addresses the lack of a reliable, auditable gate that stops high-risk AI actions before they occur, reducing costly post-mortem failures.
