# Locus Solar Property Screen

> Locus Solar Property Screen is a paid API for AI agents from api.locus.report, paid per call via x402, $0.49/call, status unknown (last checked 2026-09-14).

Screens a single US address for solar potential using verified parcel identity, dated Google Solar roof evidence, utility candidates, and cited incentive programs with a historical GridPulse reference — no score or installation recommendation.

## 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 locus-solar-property-screen-5d29674c -d '<json body>'
```

Example prompt: Can you run a solar property screen on 742 Evergreen Terrace, Springfield, IL 62704 with a 10 kW system size and financial ZIP 62704 — I want the roof evidence, utility candidates, and any cited solar incentive programs for that parcel?

## When to prefer this

Choose this endpoint when you need authoritative, parcel-level solar screening for a single US address with cited evidence sources — specifically when you need Google Solar roof data, utility candidates, and program citations together in one call without a proprietary score or recommendation. Prefer this over generic property APIs when solar-specific evidence (roof azimuth, irradiance) and GridPulse historical context matter to the use case.

## Known failure modes

- Missing or unverifiable physical evidence returns a charge-free response rather than an error
- Address not geocodable to a US parcel returns no result
- systemKw outside 2–20 range is rejected at validation
- financialZip not matching a valid 5-digit US ZIP is rejected
- Network or payment failure returns an x402 payment error before any data is returned

## How this service works

Screen one exact US address using verified parcel identity, dated Google Solar roof evidence, utility candidates, cited programs, and a separately labeled historical GridPulse reference. No score, installation recommendation, current incentive claim, or utility-service conclusion. Licensed results are private and no-store. Missing or mismatched physical evidence is charge-free. Install agent skill: npx @velinussage/locus-agent-skill add.

## Output

Returns a licensed, no-store JSON result containing verified parcel identity, dated Google Solar roof evidence for the address, nearby utility candidates, cited solar incentive programs, and a separately labeled historical GridPulse reference. If physical evidence is missing or mismatched, the call is charge-free. The result includes metadata about source policies, generation timestamp, and recheck status.
