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 halowerk-site-dossiers-school-site-land-cover-screening-5f79011e -d '<json body>'
```

Example prompt: Can you pull a HALOWERK school site dossier for the location at 52.5200° N, 13.4050° E with a 300-metre screening radius and tell me what the land-cover evidence score looks like?

## When to prefer this

Choose this endpoint when you need a fast, deterministic land-cover evidence score specifically for school site screening within Europe. It is ideal for early-stage site shortlisting where quantitative land-cover data (not planning permission or legal status) is required. Prefer it over generic geospatial APIs when you want pre-composed, decision-support dossiers formatted for educational facility siting rather than raw map tiles or zoning lookups.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) return an out-of-coverage error
- radius_m below 50 or above 2000 returns a validation error
- Invalid or missing latitude/longitude returns a parameter error
- Payment failure (x402) results in a 402 response before any data is returned

## How this service works

Decision-support dossier for school site screening using six disclosed measurements and a deterministic land-cover-priority evidence score. It is screening evidence, not a permit, valuation or legal determination.

## Output

Returns a structured site dossier containing six disclosed land-cover measurements and a deterministic land-cover-priority evidence score for the specified European location and radius. The output is framed as screening evidence to support school site decisions, explicitly not a permit, valuation, or legal determination.
