# HALOWERK Land Dossiers – Wind Farm Terrain Screening

> HALOWERK Land Dossiers – Wind Farm 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).

Returns a land-cover-priority evidence dossier for wind farm site screening at a given European coordinate, based on six disclosed 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-wind-farm-terrain-screening-2559ce7b -d '<json body>'
```

Example prompt: Can you run a wind farm land cover screening dossier for the site at latitude 53.4, longitude -1.8 using a 500-metre radius? I want the land-cover-priority evidence score to help decide if it's worth taking further.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, evidence-based land cover screening score specifically for wind farm siting within Europe. It is particularly suited for early-stage site selection, portfolio screening across multiple coordinates, or pre-feasibility due diligence where a consistent scoring methodology matters. Prefer it over generic GIS APIs when you need a packaged dossier output with disclosed measurements rather than raw geodata.

## Known failure modes

- Coordinates outside European coverage (latitude 34–72.5, longitude -31.5–40.5) return a validation error
- Radius below 50m or above 2000m is rejected with a schema validation error
- Missing latitude or longitude results in a bad request response
- Payment failure via x402 protocol returns a 402 status before processing
- Network timeout if the terrain computation takes longer than expected

## How this service works

Decision-support dossier for wind farm terrain 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

A decision-support dossier containing six disclosed land-cover measurements and a deterministic land-cover-priority evidence score for the specified European location and radius. The dossier is screening evidence only and does not constitute a permit, legal determination, or valuation.
