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 vealth-sdg-7-solar-credit-issuance-63f0d9aa -d '<json body>'
```

Example prompt: Issue SDG 7 solar credits for my site called 'Rooftop Solar Array - Building A' in Austin, Texas — it's a 12.5 kW rooftop system and I need the NREL-baseline avoided CO₂ credit calculation.

## When to prefer this

Use this endpoint when you need to programmatically issue SDG 7 solar energy carbon credits backed by NREL solar irradiance baselines and the Regen Builder Lab methodology, particularly for CDP-settled credit workflows. Prefer this over generic carbon calculators when you need formal credit issuance (not just estimation) tied to a specific rooftop solar installation with a named site and kilowatt capacity.

## Known failure modes

- Invalid or unrecognized site location causes baseline lookup failure
- rooftopKw value of zero or negative triggers validation error
- Missing required fields (siteName, rooftopKw, siteLocation) returns 400 bad request
- Payment not settled via CDP/x402 returns 402 Payment Required
- Location outside NREL coverage area returns insufficient baseline data error
- Methodology document unavailable returns 503 service error

## How this service works

sdg-7-solar (CDP-settled mirror) — SDG 7 solar credit issuance — NREL baseline + avoided CO₂ + Regen Builder Lab methodology document

## Output

Returns a solar carbon credit issuance record including the quantity of avoided CO₂ calculated via NREL baseline, credit metadata aligned with SDG 7 goals, and a reference to the Regen Builder Lab methodology document used for the computation.
