Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 homepulse-home-energy-efficiency-analyzer-67892095
```

Example prompt: What energy efficiency upgrades should I prioritize for my 2,000 sq ft 1985 ranch house in Denver — show me what qualifies for the IRA 30% tax credit and rank everything by how fast it pays back?

## When to prefer this

Use this endpoint when a homeowner or energy agent needs to evaluate and prioritize home energy efficiency investments with IRA federal tax credit calculations already factored in. Ideal for generating a ranked action plan rather than a single point estimate. Prefer over generic home improvement ROI endpoints when the specific focus is energy efficiency, utility cost reduction, and federal incentive optimization.

## Known failure modes

- Missing or invalid home address returns error — location required for climate-zone-specific calculations
- Unsupported home characteristics or missing square footage may produce less accurate recommendations
- Service unavailable (503) if underlying energy data sources are down
- Payment failure via x402 protocol if USDC balance insufficient (0.1 USDC required per call)
- IRA credit rules may be outdated if legislation changes after last update

## How this service works

Home energy efficiency upgrades ranked by payback period: heat pump, insulation, windows, and more, with IRA 30% federal tax credits applied. For homeowner and energy agents. Returns cost estimates, annual energy-bill savings, and climate-zone guidance by home type, ZIP, age, and square footage.

## Output

A ranked list of home energy efficiency improvements ordered by payback period, each annotated with estimated upfront cost, annual savings, IRA 30% tax credit amount applied, net cost after credit, and payback period in years — giving homeowners a prioritized action plan for energy investment.
