# HALOWERK Transport Corridor Terrain Screening Dossier

> HALOWERK Transport Corridor Terrain Screening Dossier 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 balanced-evidence decision-support dossier for transport corridor terrain suitability, scoring a European location using six disclosed measurements within a configurable 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-transport-corridor-terrain-screening-dossier-27e2a14a -d '<json body>'
```

Example prompt: Can you run a transport corridor terrain screening dossier for the location at 51.5074° N, -0.1278° E using a 500-metre radius and give me the balanced evidence score?

## When to prefer this

Choose this endpoint when you need rapid, cost-effective terrain screening evidence for transport corridor planning at a specific European location, especially in early-stage feasibility studies where a deterministic balanced score across six measurements is sufficient before commissioning expensive surveys. It is purpose-built for transport corridor use cases, distinguishing it from sibling endpoints covering conservation, recreation, care-home, or emergency logistics screening.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) return a validation error
- Radius below 50m or above 2000m is rejected
- Missing required latitude or longitude fields cause a 422 validation error
- Payment failure via x402 protocol blocks the response
- Location in a data-sparse region may yield incomplete measurement coverage

## How this service works

Decision-support dossier for transport corridor terrain screening using six disclosed measurements and a deterministic balanced 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 balanced evidence score indicating transport corridor suitability for the specified European location and radius. The dossier is screening evidence only and does not constitute a permit, valuation, or legal determination.
