# HALOWERK Central Land – Slovenia Water & Wetland Share

> HALOWERK Central Land – Slovenia Water & Wetland Share is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Returns the combined share of permanent water, herbaceous wetland, and mangrove land-cover classes at a given coordinate within Slovenia, derived from ESA WorldCover 2021 data.

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-central-land-slovenia-water-wetland-share-9250d5cb -d '<json body>'
```

Example prompt: What's the combined share of permanent water, herbaceous wetland, and mangrove cover at latitude 46.05, longitude 14.50 in Slovenia?

## When to prefer this

Choose this endpoint when you need a fast, per-point lookup of water and wetland land-cover fraction specifically within Slovenia, charged per call at low cost ($0.003 USDC). Prefer it over full raster downloads or GIS pipeline processing when you only need a scalar share value for a single coordinate without managing satellite imagery yourself.

## Known failure modes

- Coordinate outside Slovenia's Natural Earth boundary — request rejected before payment with a validation error
- Latitude or longitude outside published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed JSON body or missing required fields — HTTP 400 error
- Service unavailability or upstream data source error — HTTP 5xx response
- Edge coordinates near Slovenia's border may be ambiguously rejected depending on boundary resolution

## How this service works

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

## Output

A numeric fraction (share between 0 and 1, or percentage) representing the combined proportion of ESA WorldCover 2021 pixels classified as permanent water, herbaceous wetland, or mangrove within the analysis area around the given coordinate. Coordinates outside Slovenia's Natural Earth boundary are rejected before any computation or payment.
