## 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-budget-enforcer-5d1a733f
```

Example prompt: Before my AI agent sends that wire transfer, run it through GuardRoute's budget enforcer to check if it's within policy and get a route decision — the request is a GET.

## When to prefer this

Choose this endpoint when you need a real-time, pre-execution policy check on AI agent actions, wire transfers, or beneficiary changes — especially when deterministic allow/deny routing with a verifiable policy hash is required. Prefer it over generic rate-limiting or post-hoc audit tools when the goal is to intercept and gate actions before they happen.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or missing required query parameters — returns 400 Bad Request
- Policy not found or misconfigured — may return 404 or an error in the response body
- Network congestion or node unavailability — may cause timeout or 503
- Unsupported HTTP method — only GET/HEAD/POST accepted

## 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 containing: a boolean success flag, a routeDecision field (e.g. ALLOW_DETERMINISTIC or DENY), a policyHash identifying which policy was evaluated, the GuardRoute service name, the network (base), the protocol token contract address, and a link to the nodes portal.
