## 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 agentutility-building-permits-api-0fffa2ee -d '<json body>'
```

Example prompt: Can you pull up all the issued building permits in NYC for me? I need the permit IDs and their current status.

## When to prefer this

Use this endpoint when an agent needs to programmatically retrieve building permit records for a specific city, especially in automated workflows requiring pay-per-call access with USDC settlement. Prefer this over manual government portals when building real estate research tools, compliance checkers, or construction monitoring agents.

## Known failure modes

- City not found or unsupported — may return empty permits array
- Malformed request body — returns error indicating missing required fields
- Payment failure via x402 — 402 response if USDC payment not included or insufficient
- Rate limiting — too many requests in a short window
- Upstream municipal data unavailable — partial or empty results

## How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

## Output

Returns a JSON object containing the queried city, a list of permits (each with a permit_id and status such as 'issued'), and a count of permits returned.
