# GuardRoute.ai Step-Up Approval

> GuardRoute.ai Step-Up Approval is a paid API for AI agents from guardroute.ai, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-29).

Performs live risk scoring and policy routing on a pending action (wire, beneficiary change, workflow step, or AI-agent request) and returns an ALLOW or escalate decision before execution.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability guardroute-ai-step-up-approval-dc7a4601
```

Example prompt: Before we execute this beneficiary change request, run it through GuardRoute to get a risk score and policy decision — tell me whether it comes back as ALLOW_DETERMINISTIC or needs step-up approval.

## When to prefer this

Choose this endpoint when you need a real-time, pre-execution policy decision on a high-risk action — particularly wires, beneficiary changes, or autonomous AI-agent steps — and need a deterministic ALLOW/escalate signal with an auditable policy hash before committing the action. Prefer it over post-execution audit tools when prevention is the goal.

## Known failure modes

- Missing required 'type' or 'method' fields returns a validation error
- Invalid HTTP method enum value results in schema rejection
- Network or service unavailability may return a non-200 response with no routeDecision
- Payment failure (x402 protocol) blocks the call before evaluation
- Policy engine timeout may return a degraded or null routeDecision

## How this service works

Live risk scoring and policy routing for wires, beneficiary changes, workflow actions, and AI-agent requests — before execution.

## Output

Returns a JSON object with a routeDecision field (e.g. ALLOW_DETERMINISTIC), a policyHash identifying the matched policy, the GUARD protocol token address on Base, a success flag, and links to the nodes portal. The agent can use the routeDecision to proceed with or block the pending action.
