## 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 x402-trust-layer-api-router-89b01282 -d '<json body>'
```

Example prompt: Route this GET request through the x402 trust layer and tell me whether it's allowed — I need to know if my API call passes the mandate compliance and guard checks after the USDC payment settles.

## When to prefer this

Use this endpoint when you need to enforce x402 trust infrastructure controls — including guard checks, mandate compliance, and certified seller verification — on outbound HTTP requests (GET, HEAD, DELETE) with USDC micropayment settlement. Prefer this over generic API gateways when your workflow requires blockchain-anchored mandate diffs, KYM (Know Your Mandate), or semantic escrow verification.

## Known failure modes

- Payment not settled — request blocked with allowed: false
- Invalid HTTP method (only GET, HEAD, DELETE supported) — schema validation error
- Mandate check failure — allowed: false with explanation in summary
- Compliance violation detected — request rejected with summary detail
- Network or facilitator unavailability — timeout or 5xx error
- Insufficient USDC balance for $0.02 per-call fee — payment failure

## How this service works

68 paid x402 trust infrastructure APIs: guard, semantic escrow, mandate diff, certified seller network, KYM, mandates, compliance, disputes, and orchestration.

## Output

Returns a JSON object with 'ok' (boolean indicating success), 'allowed' (boolean indicating whether the request is permitted after x402 settlement), and 'summary' (a human-readable explanation of the routing decision).
