## 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 buildpulse-project-comparison-2aa0e467
```

Example prompt: I have a $40,000 budget — can you compare a kitchen remodel, a master bathroom addition, and a finished basement side by side so I can see which one has the best ROI, shortest timeline, and lowest complexity?

## When to prefer this

Use this endpoint when a user needs to choose between two or more renovation or construction projects and wants a structured, multi-dimensional comparison (cost, ROI, timeline, complexity) rather than a single project estimate. Prefer this over the single project cost estimate endpoint when decision-making between options is the goal.

## Known failure modes

- Missing or invalid budget parameter returns an error
- Unrecognized project types may return no comparison data
- Budget too low for any of the requested projects may return warnings or null estimates
- More than supported number of projects in one comparison may return a 400 error

## How this service works

BuildPulse — home construction and renovation intelligence: project cost estimates, contractor vetting, permit requirements, material pricing, ROI projections, and inspection checklists. Global coverage — jurisdiction-aware permits, codes, and costs (US and Canada deepest; UK/AU equivalents handled).

## Output

A side-by-side comparison table of the requested renovation projects showing estimated cost, ROI, timeline, and complexity rating for each, helping the user make an informed decision within their budget.
