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 gridpulse-home-carbon-footprint-emissions-analyzer-bb0de0dc
```

Example prompt: What's my home's carbon footprint from electricity? I'm in ZIP code 94110 and used about 650 kWh last month — give me the EPA eGRID emissions number and a roadmap for cutting my emissions.

## When to prefer this

Choose this endpoint when a homeowner or climate agent needs to quantify residential electricity emissions using authoritative EPA eGRID regional factors rather than generic national averages, and especially when a personalized reduction roadmap is needed alongside the raw emissions figure.

## Known failure modes

- Invalid or unrecognized ZIP code / region returns an error — no eGRID subregion can be matched
- Missing required kWh usage input causes a 400-level error
- ZIP code spans multiple eGRID subregions causing ambiguous result
- Payment of $0.05 USDC not completed triggers 402 Payment Required
- Extremely high or zero kWh values may produce implausible results

## How this service works

Home carbon footprint calculator — household electricity emissions via EPA eGRID factors by state, with a reduction roadmap. For homeowner and climate agents.

## Output

Returns the home's electricity carbon emissions in lbs CO2e based on the applicable EPA eGRID subregion emissions factor, a breakdown of how those emissions are calculated, equivalent comparisons (e.g. miles driven), and a prioritized reduction roadmap with actionable steps the homeowner can take to lower their carbon footprint.
