## 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-care-home-terrain-screening-ead05694 -d '<json body>'
```

Example prompt: Can you run a care-home site screening dossier for coordinates 48.8566° N, 2.3522° E with a 500-meter radius? I need the terrain-priority evidence score and the six site measurements to help decide if this is a viable location for a new care facility.

## When to prefer this

Choose this endpoint when you need a fast, deterministic terrain-priority screening dossier specifically for care-home site evaluation in Europe. It is ideal for early-stage feasibility work where you want objective, disclosed measurements and a reproducible evidence score rather than subjective valuations or legal opinions. Prefer it over general geospatial APIs when the use case is specifically care-home siting and you need a structured, decision-ready output at low cost.

## Known failure modes

- Coordinates outside European coverage (latitude 34–72.5°N, longitude 31.5°W–40.5°E) return an error
- radius_m below 50 or above 2000 returns a validation error
- Missing required latitude or longitude fields causes a 400-level error
- Payment failure via x402 protocol halts the request before processing

## How this service works

Decision-support dossier for care-home 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 site dossier containing six disclosed terrain measurements and a single deterministic terrain-priority evidence score for the queried European location, intended as screening evidence to support care-home site selection decisions. This is not a permit, valuation, or legal determination.
