# GuardRoute.ai Route Simulation

> GuardRoute.ai Route Simulation is a paid API for AI agents from guardroute.ai, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-30).

Simulates pre-execution risk scoring and policy routing decisions for financial transactions, beneficiary changes, and AI-agent actions before they are executed.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-route-simulation-f61ce8ef
```

Example prompt: Before we actually send this wire, can you run it through GuardRoute to simulate the routing decision and get a risk score — specifically for a POST HTTP request with the beneficiary change parameters?

## When to prefer this

Choose this endpoint when you need a deterministic, auditable pre-execution gate for financial transactions, beneficiary changes, or AI-agent actions — particularly when compliance, fraud prevention, or policy enforcement requires a logged routing decision before any irreversible action is taken. It is especially valuable when your workflow involves AI agents taking autonomous financial actions that need a human-policy backstop.

## Known failure modes

- Invalid or missing 'type' or 'method' fields in input object return schema validation errors
- Unsupported HTTP method values outside GET/HEAD/POST cause rejection
- Payment not received or insufficient USDC balance causes 402 Payment Required
- Network connectivity issues to Base blockchain may delay policy hash resolution
- Malformed query parameters or headers may result in incomplete risk assessment

## 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 route decision (e.g. ALLOW_DETERMINISTIC), a policy hash for audit trail, the GuardRoute protocol token address on Base network, a link to the nodes portal, and a success flag — enabling the caller to decide whether to proceed with the underlying action.
