# HALOWERK Site Dossiers – Outdoor Recreation Terrain Screening

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

Generates a deterministic terrain-priority evidence dossier for outdoor recreation land screening using six disclosed measurements at a given European coordinate and radius.

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-outdoor-recreation-terrain-screening-1ff30f85 -d '<json body>'
```

Example prompt: Can you run a terrain screening dossier for outdoor recreation on the coordinates 48.2092° N, 16.3728° E with a 500-meter radius? I need the six terrain measurements and the terrain-priority evidence score.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, terrain-focused evidence score specifically for outdoor recreation land screening in Europe. It is distinct from the conservation, transport corridor, care-home, and emergency logistics dossier variants on the same platform. Use it when you require a reproducible, six-measurement terrain dossier for site screening decisions rather than full planning, legal, or valuation assessments.

## Known failure modes

- Coordinates outside European coverage bounds (latitude 34–72.5°N, longitude -31.5–40.5°E) will return an error
- radius_m below 50 or above 2000 will be rejected as out of range
- Invalid or missing latitude/longitude fields return a validation error
- Payment failure via x402 protocol results in a 402 response before dossier generation
- Internal computation errors may return a 5xx response for edge-case terrain geometries

## How this service works

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

## Output

Returns a decision-support dossier containing six disclosed terrain measurements and a deterministic terrain-priority evidence score for outdoor recreation land screening at the requested European location and radius. The dossier is screening evidence only and does not constitute a permit, valuation, or legal determination.
