# HALOWERK Land Dossiers – Hospital Site Screening

> HALOWERK Land Dossiers – Hospital Site 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 land-cover-priority evidence dossier for screening potential hospital sites within European coverage, returning six measurements and 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-screening-ab3d2d1d -d '<json body>'
```

Example prompt: Can you run a hospital site screening dossier for the coordinates 48.8566° N, 2.3522° E using a 500-metre radius and give me the land-cover evidence score?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, land-cover-based evidence score specifically for hospital site screening within Europe. It is optimised for early-stage site triage where a standardised six-metric dossier is sufficient before commissioning full surveys. Prefer sibling endpoints for other use cases such as housing, hotels, solar farms, schools, or offices.

## Known failure modes

- Coordinates outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) will result in a validation error
- radius_m below 50 or above 2000 will be rejected
- Missing required latitude or longitude fields cause a 400-level error
- Payment failure or insufficient USDC balance will block the request under x402 protocol

## How this service works

Decision-support dossier for hospital 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 decision-support dossier containing six disclosed land-cover measurements and a deterministic land-cover-priority evidence score for the specified location and radius. The dossier is intended as screening evidence only — not a permit, legal determination, or property valuation.
