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-hotel-land-cover-screening-9b66bb75 -d '<json body>'
```

Example prompt: Can you run a hotel land cover screening dossier for the site at latitude 48.8566, longitude 2.3522, using a 500-metre radius — I need the evidence score and measurements to support our pre-feasibility review?

## When to prefer this

Use this endpoint when you need a fast, deterministic, quantitative land-cover screening score for a European hotel development candidate, specifically using land-cover as the primary evidence axis. Prefer it over generic mapping or GIS APIs when you need a structured dossier with six standardised measurements and a priority score ready for decision support. Choose the hotel variant (this endpoint) over sibling endpoints for housing, office, solar or hospital when the end use is hospitality/hotel development.

## Known failure modes

- Coordinates outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) return a validation error
- Radius below 50 m or above 2000 m returns a parameter validation error
- Missing required latitude or longitude fields return a 422 or 400 error
- Network or service unavailability returns a 5xx response
- Payment not settled (x402 protocol) results in a 402 Payment Required response

## How this service works

Decision-support dossier for hotel 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 decision-support dossier containing six disclosed land-cover measurements and a deterministic land-cover-priority evidence score for the specified location and radius. The output is screening evidence only — not a permit, valuation, or legal determination.
