## 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-belgium-water-wetland-share-d1e8f89c -d '<json body>'
```

Example prompt: What is the combined water, wetland, and mangrove land-cover share for the coordinate 51.0543° N, 3.7174° E in Belgium?

## When to prefer this

Use this endpoint when you need a precise, point-level hydric land-cover fraction (water + wetland + mangrove) for a specific location in Belgium, especially for environmental screening, flood risk, or land-use analysis workflows that require ESA WorldCover-derived statistics. It is preferable over general GIS APIs when you need a low-latency, pay-per-call lookup without setting up your own raster analysis pipeline.

## Known failure modes

- Coordinate outside Belgium boundary: rejected before payment with a validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation error
- Malformed JSON body or missing required fields: 400 Bad Request
- Payment failure via x402 protocol: 402 Payment Required

## How this service works

Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Belgium; 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 centred on the requested Belgian coordinate. Coordinates outside Belgium's Natural Earth boundary are rejected before billing.
