# HALOWERK Site Dossiers – Conservation Terrain-First Screening

> HALOWERK Site Dossiers – Conservation Terrain-First Screening is a paid API for AI agents from standortdossier.halowerk.com, paid per call via x402, $0.012/call, status unknown (last checked 2026-09-14).

Generates a terrain-priority evidence dossier for conservation opportunity screening at a European location, returning six disclosed measurements and a deterministic terrain-priority 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-site-dossiers-conservation-terrain-first-screening-4c7b7221 -d '<json body>'
```

Example prompt: Can you pull a conservation terrain-priority dossier for the coordinates 51.5074°N, 9.9936°E with a 500-metre radius? I need the six terrain measurements and the deterministic evidence score to decide whether this site in central Germany is worth pursuing for habitat restoration.

## When to prefer this

Choose this endpoint when you need terrain-priority evidence specifically for conservation or habitat screening at a European location and want a deterministic, reproducible score rather than a subjective assessment. It is distinct from the outdoor recreation, transport corridor, care-home, and emergency logistics siblings by its conservation-specific scoring logic. Prefer it over generic GIS tools when you need a packaged, single-call decision-support output with six standardised measurements.

## Known failure modes

- Coordinates outside the European coverage bounds (lat 34–72.5, lon -31.5–40.5) will result in a validation error
- Radius below 50 m or above 2000 m will be rejected
- Missing required latitude or longitude parameters causes a bad request error
- Payment failure via x402 protocol may prevent access to the dossier
- Network timeouts on the remote terrain data pipeline

## How this service works

Decision-support dossier for conservation opportunity 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 intended to inform conservation opportunity decisions — it is explicitly not a permit, legal determination, or property valuation.
