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-terrain-priority-screening-6c084e98 -d '<json body>'
```

Example prompt: Can you run a terrain-priority office development screening dossier for the site at latitude 51.505, longitude -0.09 in London, using a 300-metre radius? I need the six terrain measurements and the evidence score to evaluate whether this location is suitable for an office building.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, terrain-first evidence score specifically for office development screening at a European location. It is distinct from the housing, hotel, solar, hospital, and school variants on the same platform — use this one when the intended land use is commercial office development. Prefer it over general geospatial APIs when you need a pre-packaged, development-type-specific dossier rather than raw terrain data.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will return a validation error
- Radius below 50m or above 2000m will be rejected
- Missing latitude or longitude fields will produce a schema validation error
- Payment failure via x402 protocol will prevent dossier generation
- Ambiguous or invalid coordinate formats may result in an error response

## How this service works

Decision-support dossier for office development 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 decision-support dossier containing six disclosed terrain measurements and a single deterministic terrain-priority evidence score for the submitted European coordinates and radius. The output is screening evidence intended to inform office development site evaluation — it is not a permit, property valuation, or legal determination.
