# HALOWERK Land Dossiers – Hospital Site Terrain Screening

> HALOWERK Land Dossiers – Hospital Site Terrain Screening is a paid API for AI agents from landdossier.halowerk.com, paid per call via x402, $0.012/call, status unknown (last checked 2026-09-15).

Generates a terrain-priority decision-support dossier for screening potential hospital development sites in Europe, scoring six disclosed terrain measurements into a deterministic evidence score.

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-land-dossiers-hospital-site-terrain-screening-13566688 -d '<json body>'
```

Example prompt: Can you run a hospital site terrain screening dossier for coordinates 51.5074° N, -0.1278° E using a 500-meter radius and give me the terrain-priority evidence score and all six measurements?

## When to prefer this

Choose this endpoint when you need a rapid, deterministic terrain evidence score specifically for hospital or healthcare facility site screening within European geographic coverage. It is purpose-built for healthcare land use (vs. the sibling endpoints for housing, hotels, solar, or offices) and provides six terrain-specific measurements tailored to hospital siting criteria. Prefer it over generic geospatial or land registry APIs when you need a pre-packaged, reproducible terrain evidence score for early-stage decision support without requiring full environmental or planning assessments.

## Known failure modes

- Coordinates outside European coverage (latitude 34–72.5°N, longitude -31.5–40.5°E) will be rejected
- Radius below 50m or above 2000m will be rejected
- Missing latitude or longitude returns a validation error
- Payment failure via x402 protocol results in 402 response and no dossier returned
- Malformed numeric inputs return schema validation errors

## How this service works

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

## Output

A structured decision-support dossier containing six disclosed terrain measurements and a single deterministic terrain-priority evidence score for the queried location and radius. The dossier is screening evidence only — it does not constitute a permit, property valuation, or legal determination regarding hospital development suitability.
