## 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 vealth-lbc-living-building-challenge-property-scanner-954701da -d '<json body>'
```

Example prompt: Can you run an LBC petal scan on 123 Main St, Portland OR — the building is 2400 sqft, has an occupancy of 8 people, and we have a $50000 renovation budget?

## When to prefer this

Choose this endpoint when you need a structured, multi-dimensional sustainability scorecard for a specific property using the Living Building Challenge petal framework, especially when you have concrete building parameters (sqft, occupancy, budget) and want quantified scores across all seven LBC categories. Prefer this over generic green-building APIs when you specifically need LBC petal methodology.

## Known failure modes

- Missing or unrecognizable address returns an error or low-confidence scorecard
- Non-numeric sqft or budget values cause schema validation failure
- Occupancy of zero or negative number may produce unexpected scoring behavior
- Address outside supported geographic coverage may return null or default petal values
- Payment failure via x402 prevents the scan from being executed
