Layer3x is a runtime execution authorization platform for AI agents operating in financial and payment workflows. Before any AI-generated payment executes, it passes through Layer3x. The response is one of three deterministic signals:

​
🟢 GO

Policy validated. Action authorized. Proceed with execution.

​
🔴 NO-GO

Blocked by policy. Reason logged. Webhook fired to your systems.

​
🟡 EXCEPTION

Anomaly detected — hash mismatch or silent timeout. Transaction frozen pending reconciliation.

​
What Layer3x is not

  • Not an IAM tool — IAM grants access to systems. Layer3x governs whether a specific AI-generated action should execute right now.
  • Not a workflow tool — workflow tools orchestrate sequences. Layer3x intercepts at the execution boundary.
  • Not an AI monitoring tool — monitoring observes after the fact. Layer3x blocks before execution.
