# HALOWERK Site Dossiers – Transport Corridor Land-Cover Screening

> HALOWERK Site Dossiers – Transport Corridor Land-Cover 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).

Returns a deterministic land-cover-priority evidence score and six terrain measurements for a given European location, screening suitability for transport corridor planning.

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-transport-corridor-land-cover-screening-76118c36 -d '<json body>'
```

Example prompt: Can you run a HALOWERK transport corridor land-cover screening for the location at 48.137° N, 11.576° E with a 500-meter radius and tell me the evidence score and terrain measurements?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, land-cover-focused terrain screening score for a transport corridor site within Europe. It is purpose-built for transport infrastructure siting (roads, rail, logistics corridors) as opposed to conservation, recreation, or care-home screening endpoints on the same platform. Prefer it over generic GIS APIs when you need a pre-packaged evidence dossier with a single composite score rather than raw raster data.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) return an out-of-coverage error
- Radius below 50m or above 2000m returns a validation error
- Malformed or missing required fields (latitude, longitude) return a 400-level error
- Payment failure via x402 protocol results in an authorization error before processing

## How this service works

Decision-support dossier for transport corridor 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 terrain measurements and a deterministic land-cover-priority evidence score for the specified European location and radius. The result is screening evidence only — not a permit, legal determination, or valuation.
