## 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-agent-wallet-receipt-gate-policy-3c26fa90
```

Example prompt: What's the receipt gate policy for the x402 route — specifically the required network and max receipt age of 300 seconds — so I can verify the pay-to address, replay rules, and gate checks before proceeding with the downstream action?

## When to prefer this

Use this endpoint when an AI agent needs to inspect or enforce the x402 payment receipt validation policy for a specific route before executing or gating a downstream action. Prefer this over hardcoding payment parameters when the policy (network, replay rules, pay-to address) may vary by route or change over time.

## Known failure modes

- Invalid or unsupported requiredNetwork value returns a 400 error
- maxAgeSeconds out of acceptable range returns a validation error
- Malformed request body returns a 422 unprocessable entity
- Service unavailable returns a 503 with no policy data
- Payment of 0.002 USDC not received results in 402 Payment Required before policy is returned

## How this service works

A buyer-side control console for signature risk, EIP-712 review, transaction decoding, ERC20 allowance risk, Permit/Permit2 approvals, transaction simulation summaries, spend guard policy, receipt gate enforcement, and private-key boundaries.

## Output

A policy object specifying the required blockchain network, required HTTP headers, pay-to address, maximum receipt age (replay window), and gate check rules that must be satisfied for downstream x402-protected actions to proceed.
