# HALOWERK Site Dossiers – Conservation Land-Cover Priority Screening

> HALOWERK Site Dossiers – Conservation Land-Cover Priority 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 decision-support dossier for conservation opportunity screening at a European location using six disclosed measurements and a deterministic land-cover-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-land-cover-priority-screening-b88a5c25 -d '<json body>'
```

Example prompt: Can you run a conservation land-cover priority screening dossier for coordinates 51.4°N, 9.8°E with a 500-metre radius? I want to see the evidence score and the six site measurements to decide if this area is worth investigating further for habitat protection.

## When to prefer this

Use this endpoint when you need a fast, deterministic, evidence-based conservation screening score for a specific European location — especially in early-stage site evaluation workflows where you want objective land-cover priority signals before committing to full ecological surveys. Prefer it over generic GIS lookups when you need a structured dossier with multiple measurements in a single call. Not suitable for legal determinations, valuations, or non-European geographies.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5°N, lon -31.5–40.5°E) return a validation error
- radius_m below 50 or above 2000 returns a parameter out-of-range error
- Payment failure (x402) if USDC balance is insufficient or payment header is malformed
- Missing required latitude or longitude fields returns a 400 bad request
- Service unavailable if the underlying land-cover dataset is temporarily inaccessible

## How this service works

Decision-support dossier for conservation opportunity 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 structured decision-support dossier containing six disclosed site measurements and a deterministic land-cover-priority evidence score for the specified European location and radius. The dossier is intended as screening evidence to inform conservation opportunity assessments, not a legal, valuation, or permit determination.
