Components

UAPK Gateway: Evaluate

Checks an action against your policies without executing it. Use as a gate before any tool call in your flow.

Inputs:

• Gateway URL, Org ID, API Key
• UAPK ID, Agent Instance ID, Action Type, Tool
• Parameters (JSON), Counterparty details (optional), Amount (optional)

Outputs: decision (allow/deny/escalate), full evaluation response

UAPK Gateway: Execute

Evaluates the policy and executes the action if allowed. Returns the connector's result alongside the policy decision.

Inputs: Same as Evaluate, plus optional Override Token for re-submitting an approved escalation.

Outputs: Execution result, decision, approval ID (if escalated)

Quickstart

1. Add the UAPK Gateway: Execute component to your flow
2. Connect your agent's action output to its inputs
3. Connect the component's decision output to a Router or Conditional component
4. Route allow → continue, deny → stop/alert, escalate → human approval step
