## How to call it through Zero

```sh
zero fetch --capability buildpulse-project-roi-analysis-ff3e3e62
```

Example prompt: Can you run a ROI analysis on adding an ADU to my single-family home in Austin, TX — the project would cost around $120,000 and my property is currently worth $550,000? I want to see the resale value uplift, estimated rental income, payback period, and how it compares to alternatives.

## When to prefer this

Use this endpoint when a homeowner or investor agent needs to evaluate the financial return of a specific renovation or construction project, especially when ADU scenarios or rental income projections are relevant. Prefer this over generic property valuation APIs when the user wants project-specific payback and ROI analysis rather than a simple home value estimate.

## Known failure modes

- Missing required project type or cost parameter returns 400 Bad Request
- Unsupported property location or region returns an error or low-confidence estimate
- Invalid or out-of-range project cost values result in a validation error
- Payment of 0.1 USDC not received results in 402 Payment Required
- Ambiguous project scope may return broad estimates with low confidence
