## How to call it through Zero

```sh
zero fetch --capability buildpulse-roi-analyzer-03893606
```

Example prompt: What's the ROI on adding an ADU to my 3-bedroom home in Austin, TX — I'm planning to spend around $150,000 and want to know the resale value boost, rental income I could expect, how long it'll take to pay back, and whether there's a better alternative project for that budget.

## When to prefer this

Use this endpoint when a homeowner or investor agent needs to evaluate the financial return of a specific home improvement project, especially when ADU scenarios, rental income modeling, or comparison against alternative projects is needed. Prefer over generic cost estimators when the primary question is 'is this worth it financially?' rather than 'how much will this cost?'

## Known failure modes

- Missing or invalid project type returns an error or empty result
- Unsupported geographic location may yield low-confidence estimates
- Insufficient project scope details may result in wide estimate ranges
- Network or service unavailability returns a 5xx error
