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-housing-land-cover-priority-screening-75f3c5ff -d '<json body>'
```

Example prompt: Can you run a housing land screening dossier for coordinates 52.3676° N, 4.9041° E with a 500-metre radius and give me the land-cover-priority evidence score?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, evidence-based land-cover screening score specifically for housing development at a European location. It is purpose-built for housing use (vs sibling endpoints for solar, office, hotel, school, or hospital), uses a transparent six-measurement methodology, and is priced per call for lightweight pre-acquisition or feasibility workflows where a full planning report is not yet warranted.

## Known failure modes

- Coordinates outside the European coverage window (lat 34–72.5, lon -31.5–40.5) return a coverage error
- radius_m outside 50–2000 metre bounds returns a validation error
- Missing latitude or longitude returns a 400 bad request
- Service unavailability or payment failure returns a 402 or 5xx error

## How this service works

Decision-support dossier for housing land 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 land measurements and a deterministic land-cover-priority evidence score for the housing use case at the requested European location and radius. This is screening evidence only — not a permit, valuation, or legal determination.
