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-screening-51395e15 -d '<json body>'
```

Example prompt: Can you run an office development screening dossier for the site at 51.5074° N, -0.1278° E using a 300-metre radius and give me the balanced evidence score and all six measurements?

## When to prefer this

Use this endpoint when you need a fast, deterministic, reproducible screening score for an office development candidate site anywhere in Europe. It is ideal for early-stage site selection, investor briefings, or portfolio screening where you need objective evidence summaries before commissioning expensive surveys. Prefer it over generic GIS queries or planning databases when you want a pre-packaged, balanced multi-factor score specifically calibrated for office land use. Sibling endpoints cover housing, hotel, solar farm, hospital, and school sites — choose this one specifically for office development contexts.

## Known failure modes

- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) return an error
- radius_m outside allowed range (50–2000 m) returns a validation error
- Missing required latitude or longitude fields returns a bad request error
- Payment failure via x402 protocol prevents dossier generation
- Server error if underlying measurement data is unavailable for the requested location

## How this service works

Decision-support dossier for office development 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 land measurements and a single deterministic balanced evidence score indicating office development suitability for the specified European location and radius. This is screening evidence only — not a planning permit, legal determination, or property valuation.
