## 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-solar-panel-savings-payback-calculator-9e34ad1a
```

Example prompt: Can you run a solar feasibility analysis for my home in Austin, Texas — I use about 1,200 kWh per month and I'm considering a 10kW system? Include the payback period, annual savings, and how much I'd get from the IRA 30% tax credit.

## When to prefer this

Use this endpoint when a user wants a residential solar investment analysis — specifically payback period, IRA tax credit savings, and production estimates — rather than general grid carbon data, community solar programs, or EV charging costs. Prefer over generic solar calculators when IRA 30% tax credit breakdown and per-state accuracy are needed.

## Known failure modes

- Missing or invalid state/location input returns 400 error
- System size out of feasible residential range may return validation error
- Unsupported region or insufficient solar irradiance data may return partial or null production estimate
- Rate limit exceeded returns 429
- Payment not processed (x402) blocks the response
