# HALOWERK Telecom Mast Terrain Screening Dossier

> HALOWERK Telecom Mast 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 deterministic terrain-priority evidence dossier for evaluating a location's suitability for telecom mast placement, based on six disclosed terrain 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-telecom-mast-terrain-screening-dossier-3f38a8af -d '<json body>'
```

Example prompt: Run a terrain screening dossier for a potential telecom mast site at 51.5074°N, 0.1278°W using a 500-meter radius and give me the terrain-priority evidence score and all six measurements.

## When to prefer this

Choose this endpoint when you need fast, deterministic terrain-priority evidence for a specific European coordinate to support early-stage telecom mast site screening. It is ideal for filtering candidate locations before committing to detailed surveys, permit applications, or costly field assessments. Prefer this over general geospatial APIs when you specifically need the six-measurement terrain dossier format with a single evidence score tailored to telecom infrastructure siting.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will be rejected
- Radius below 50m or above 2000m will be rejected
- Missing required latitude or longitude parameters returns a validation error
- Payment failure via x402 protocol prevents dossier generation
- Locations in data-sparse terrain may return lower-confidence measurements

## How this service works

Decision-support dossier for telecom mast terrain 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 decision-support dossier containing six disclosed terrain measurements and a single deterministic terrain-priority evidence score for the queried location and radius. The output is screening evidence only — not a permit, valuation, or legal determination — intended to support early-stage site selection decisions for telecom mast placement.
