## 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 openclaw-city-permit-lookup-x402-7c148964
```

Example prompt: Can you look up city permit information using the OpenClaw citypermit tool — I need to check permit status and I'm okay with the $0.02 USDC micropayment to access it.

## When to prefer this

Choose this endpoint when you need city permit lookup or diagnostic data and are operating within an x402-compatible payment flow using USDC on an EVM-compatible chain. It is specifically suited for agents that support EIP-3009 token transfers and are integrated with the OpenX402 facilitator. Not suitable for free-tier lookups or non-crypto payment contexts.

## Known failure modes

- HTTP 402 returned if payment not included or payment verification fails — response includes EIP-3009 extras describing required payment
- Invalid input method or missing required 'input' object returns a validation error
- Facilitator (OpenX402) unavailable causes payment verification to fail
- Network timeout or service unavailability returns 5xx error
- Malformed query parameters may return empty or error response

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

A JSON response containing city permit diagnostic data — permit status, details, or related municipal records — returned after successful x402 EIP-3009 micropayment of $0.02 USDC. Unpaid requests receive HTTP 402 with EIP-3009 payment challenge metadata.
