# AgentRXI Solar Potential

> AgentRXI Solar Potential is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-15).

Returns rooftop solar potential for any address or coordinates, including yearly/monthly PVWatts output, sun hours, capacity factor, estimated savings, install cost, and payback period.

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 agentrxi-solar-potential-79b5198c
```

Example prompt: What's the solar potential for 742 Evergreen Terrace, Springfield, IL? Assume a 6kW system, electricity at $0.14 per kWh, and $3.00 per watt install cost — give me yearly output, estimated savings, and payback period.

## When to prefer this

Use this endpoint when you need solar energy production estimates, financial ROI analysis (savings, install cost, payback), or sun-hours data for a specific US address or coordinate pair. It wraps NREL PVWatts directly with financial overlays so you don't need to chain a separate geocoding + PVWatts call. Prefer it over generic energy APIs when the user specifically asks about rooftop solar viability, monthly output profiles, or payback analysis.

## Known failure modes

- Address not geocodable — returns error if 'near' param cannot be resolved to coordinates
- Coordinates outside NREL coverage area (non-US locations may have limited or no data)
- Missing required input type/method fields cause schema validation errors
- Extreme or unrealistic system parameters (e.g. system_kw of 0) may produce unexpected results
- Payment not completed — x402 payment required before response is returned

## How this service works

Solar potential for any address or coordinates: yearly and monthly output of a rooftop system (NREL PVWatts), sun hours, capacity factor, plus estimated yearly savings, install cost and simple payback years.

## Output

Returns yearly and monthly energy output in kWh (from NREL PVWatts), peak sun hours, capacity factor, estimated annual electricity savings in dollars, total system install cost, and simple payback period in years — all computed for the specified location and system parameters.
