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-austria-water-wetland-share-0a8a8414 -d '<json body>'
```

Example prompt: What's the combined permanent water, wetland, and mangrove land-cover share at latitude 47.8 and longitude 13.05 in Austria — I need it for an environmental assessment.

## When to prefer this

Choose this endpoint when you need ESA WorldCover-derived water and wetland land-cover fractions specifically for points within Austria. It is ideal for environmental assessments, flood-risk proxies, habitat analysis, and infrastructure planning where aquatic land-cover share is a required input. It is more cost-efficient than downloading and processing full ESA WorldCover tiles yourself, and it validates coordinates against Austrian boundaries before billing.

## Known failure modes

- Coordinate outside Austrian boundary — rejected before payment with a boundary-validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing input parameters — 400-level error
- Service unavailability or upstream data error — 5xx response

## How this service works

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

## Output

A numeric share (fraction or percentage) representing the combined proportion of ESA WorldCover 2021 pixels classified as permanent water, herbaceous wetland, or mangrove within the neighborhood of the queried coordinate in Austria. Requests outside Austrian boundaries are rejected before billing.
