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-office-development-land-cover-screening-58b421ef -d '<json body>'
```

Example prompt: Can you run an office development land-cover screening dossier for the site at 51.5074° N, -0.1278° E with a 400-metre radius? I need the six land-cover measurements and the priority evidence score to support a planning decision.

## When to prefer this

Use this endpoint when you need a fast, deterministic, land-cover-based evidence score specifically for office development screening at a known European coordinate. It is purpose-built for office use type — prefer it over the sibling housing, hotel, solar, hospital, or school endpoints when the development intent is office. It is best used early in the site assessment pipeline for rapid triage before commissioning expensive surveys or legal reviews.

## Known failure modes

- Coordinates outside European coverage (latitude 34–72.5°N, longitude −31.5–40.5°E) will return a coverage error
- Radius below 50m or above 2000m will fail schema validation
- Missing latitude or longitude fields will cause a request error
- Payment failure via x402 protocol will prevent dossier generation
- Ambiguous or imprecise coordinates may return scores for an unintended land parcel

## How this service works

Decision-support dossier for office development 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-cover measurements for the specified radius around the coordinate, plus a deterministic land-cover-priority evidence score indicating suitability for office development. Explicitly framed as screening evidence, not a permit, legal determination, or valuation.
