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-atlantic-land-netherlands-water-wetland-share-2ec74721 -d '<json body>'
```

Example prompt: What fraction of the land around latitude 52.37, longitude 4.89 in the Netherlands is classified as permanent water, herbaceous wetland, or mangrove?

## When to prefer this

Choose this endpoint when you need a precise, pre-computed water and wetland land-cover fraction for a specific point within the Netherlands, sourced from satellite-derived land classification (aligned with ESA WorldCover-style datasets). It is ideal for environmental due diligence, ecological assessments, flood-risk screening, or land suitability analyses where aquatic land-cover share is a key input. Prefer it over generic geospatial APIs when you specifically need the combined permanent-water + wetland + mangrove class share and want automatic boundary validation for the Netherlands.

## Known failure modes

- Coordinate outside Netherlands boundary: request rejected with a validation error before payment
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Missing required latitude or longitude parameter: 400-style error
- Network timeout or upstream data unavailability: transient 5xx error

## How this service works

Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Netherlands; results outside it are rejected before payment.

## Output

A numeric fraction (0–1 or percentage) representing the combined share of ESA land-cover pixels classified as permanent water, herbaceous wetland, and mangrove within the analysis grid around the provided Netherlands coordinate. The coordinate is validated against the Netherlands Natural Earth boundary; requests outside it are rejected before any charge is applied.
