# HALOWERK Site Dossiers – Conservation Opportunity Screening (Balanced)

> HALOWERK Site Dossiers – Conservation Opportunity Screening (Balanced) 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 balanced evidence dossier for conservation opportunity screening at a European geographic location, scoring six disclosed measurements with a deterministic balanced 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-opportunity-screening-balanced-75c407bb -d '<json body>'
```

Example prompt: Can you run a conservation opportunity screening dossier for the site at 51.5°N, 9.2°E using a 500-meter radius and tell me the balanced evidence score and what the six measurements show?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, reproducible conservation screening score for a specific European site — particularly when you need balanced (not bias-weighted) evidence across six disclosed metrics. Prefer it over generic GIS queries or manual data aggregation when you want a single structured dossier ready for decision-support workflows. Use the 'balanced' variant when equal weighting across evidence dimensions is appropriate; sibling endpoints serve transport, care-home, recreation, and logistics screening needs.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will be rejected
- radius_m below 50 or above 2000 will fail validation
- Missing or malformed latitude/longitude returns a 400-level error
- Payment failure or insufficient USDC balance blocks the call (x402 protocol)
- No data coverage for very remote or island locations within nominal bounds

## How this service works

Decision-support dossier for conservation opportunity screening using six disclosed measurements and a deterministic balanced evidence score. It is screening evidence, not a permit, valuation or legal determination.

## Output

A structured decision-support dossier containing six disclosed conservation-relevant measurements for the queried location and radius, plus a single deterministic balanced evidence score summarizing overall conservation opportunity. The dossier is explicitly screening evidence and does not constitute a permit, legal determination, or valuation.
