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-land-dossiers-wind-farm-terrain-screening-97f0037d -d '<json body>'
```

Example prompt: Run a HALOWERK wind farm terrain dossier for the coordinates 55.3°N, 8.7°E with a 500-metre radius and give me the terrain-priority evidence score and the six terrain measurements.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, cost-effective terrain evidence score for wind farm site screening in Europe — particularly during early-stage shortlisting before commissioning expensive physical surveys. It is purpose-built for wind farm terrain assessment and produces a comparable, reproducible score, making it well-suited for multi-site portfolio screening or automated pipelines. Prefer alternatives if you need solar, housing, or other development-type dossiers (covered by sibling endpoints), or if you require planning permission guidance, legal determinations, or valuations.

## Known failure modes

- Coordinates outside European coverage bounds (latitude 34–72.5°N, longitude -31.5–40.5°E) return a validation error
- radius_m below 50 or above 2000 returns an out-of-range error
- Malformed or missing latitude/longitude fields return a 400 bad request
- Payment failure via x402 protocol returns a 402 payment required response
- Service unavailability returns a 503 or timeout error

## How this service works

Decision-support dossier for wind farm 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 a deterministic terrain-priority evidence score and six disclosed terrain measurements for the specified coordinate and radius. The result is screening evidence only — it is not a permit, valuation, or legal determination regarding wind farm development suitability.
